Jonathan Brassow be83651f00 DM RAID: Add message/status support for changing sync action
DM RAID:  Add message/status support for changing sync action

This patch adds a message interface to dm-raid to allow the user to more
finely control the sync actions being performed by the MD driver.  This
gives the user the ability to initiate "check" and "repair" (i.e. scrubbing).
Two additional fields have been appended to the status output to provide more
information about the type of sync action occurring and the results of those
actions, specifically: <sync_action> and <mismatch_cnt>.  These new fields
will always be populated.  This is essentially the device-mapper way of doing
what MD controls through the 'sync_action' sysfs file and shows through the
'mismatch_cnt' sysfs file.

Daniel Lezcano 4c637b2175 cpuidle: make a single register function for all
The usual scheme to initialize a cpuidle driver on a SMP is:

	cpuidle_register_driver(drv);
	for_each_possible_cpu(cpu) {
		device = &per_cpu(cpuidle_dev, cpu);
		cpuidle_register_device(device);
	}

This code is duplicated in each cpuidle driver.

On UP systems, it is done this way:

	cpuidle_register_driver(drv);
	device = &per_cpu(cpuidle_dev, cpu);
	cpuidle_register_device(device);

On UP, the macro 'for_each_cpu' does one iteration:

#define for_each_cpu(cpu, mask)                 \
        for ((cpu) = 0; (cpu) < 1; (cpu)++, (void)mask)

Hence, the initialization loop is the same for UP than SMP.

Beside, we saw different bugs / mis-initialization / return code unchecked in
the different drivers, the code is duplicated including bugs. After fixing all
these ones, it appears the initialization pattern is the same for everyone.

Please note, some drivers are doing dev->state_count = drv->state_count. This is
not necessary because it is done by the cpuidle_enable_device function in the
cpuidle framework. This is true, until you have the same states for all your
devices. Otherwise, the 'low level' API should be used instead with the specific
initialization for the driver.

Let's add a wrapper function doing this initialization with a cpumask parameter
for the coupled idle states and use it for all the drivers.

That will save a lot of LOC, consolidate the code, and the modifications in the
future could be done in a single place. Another benefit is the consolidation of
the cpuidle_device variable which is now in the cpuidle framework and no longer
spread accross the different arch specific drivers.

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.

An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.

Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.

Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.

Thanks to Stephen Rothwell and Antonio Quartulli for help with several
of these merge resolutions.

Linus Torvalds 830ac8524f Merge branch 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull kdump fixes from Peter Anvin:
 "The kexec/kdump people have found several problems with the support
  for loading over 4 GiB that was introduced in this merge cycle.  This
  is partly due to a number of design problems inherent in the way the
  various pieces of kdump fit together (it is pretty horrifically manual
  in many places.)

  After a *lot* of iterations this is the patchset that was agreed upon,
  but of course it is now very late in the cycle.  However, because it
  changes both the syntax and semantics of the crashkernel option, it
  would be desirable to avoid a stable release with the broken
  interfaces."

I'm not happy with the timing, since originally the plan was to release
the final 3.9 tomorrow.  But apparently I'm doing an -rc8 instead...

Arnd Bergmann f54ae513d3 Merge branch 'spear/dwdma' into late/cleanup
This is a series originally prepared for inclusion in 3.9, which did
not work out because of dependencies on the dmaengine driver. All the
changes for the dmaengine code are merged in 3.9 now, so we can finally
do the switchover and remove the now unnecessary dma definitions for
spear13xx from the platform code.

The dma platform_data actually made up the majority of the spear13xx
platform code overall, so moving that into device tree files makes the
code substantially smaller.

* spear/dwdma:
  ata: arasan: remove the need for platform_data
  ARM: SPEAr13xx: Pass generic DW DMAC platform data from DT
  serial: pl011: use generic DMA slave configuration if possible
  spi: pl022: use generic DMA slave configuration if possible

Arnd Bergmann e34d3865ee ata: arasan: remove the need for platform_data
This adds a complete DT binding for the arasan device driver. There is
currently only one user, which is the spear13xx platform, so we don't
actually have to parse all the properties until another user comes in,
but this does use the generic DMA binding to find the DMA channel.

The patch is untested so far and is part of a series to convert
the spear platform over to use the generic DMA binding, so it
should stay with the rest of the series.

Frederic Weisbecker d1e43fa5f8 nohz: Ensure full dynticks CPUs are RCU nocbs
We need full dynticks CPU to also be RCU nocb so
that we don't have to keep the tick to handle RCU
callbacks.

Make sure the range passed to nohz_full= boot
parameter is a subset of rcu_nocbs=

The CPUs that fail to meet this requirement will be
excluded from the nohz_full range. This is checked
early in boot time, before any CPU has the opportunity
to stop its tick.

Frederic Weisbecker 0453b435df nohz: Force boot CPU outside full dynticks range
The timekeeping job must be able to run early on boot
because there may be some pre-SMP (and thus pre-initcalls )
components that rely on it. The IO-APIC is one such users
as it tests the timer health by watching jiffies progression.

Given that it happens before we know the initial online
set, we can't rely on it to select a timekeeper. We need
one before SMP time otherwise we simply crash on boot.

To fix this and keep things simple for now, force the boot CPU
outside of the full dynticks range in any case and do this early
on kernel parameter parsing time.

We might want a trickier solution later, expecially for aSMP
architectures that need to assign housekeeping tasks to arbitrary
low power CPUs.

But it's still first pass KISS time for now.

Michael Neuling 517b731477 powerpc/ptrace: Add DAWR debug feature info for userspace
This adds new debug feature information so that the DAWR can be
identified by userspace tools like GDB.

Unfortunately the DAWR doesn't sit nicely into the current description
that ptrace provides to userspace via struct ppc_debug_info.  It doesn't
allow for specifying that only some ranges are possible or even the end
alignment constraints (DAWR only allows 512 byte wide ranges which can't
cross a 512 byte boundary).

After talking to Edjunior Machado (GDB ppc developer), it was decided
this was the best approach.  Just mark it as debug feature DAWR and
tools like GDB can internally decide the constraints.

Yinghai Lu c729de8fce x86, kdump: Set crashkernel_low automatically
Chao said that kdump does does work well on his system on 3.8
without extra parameter, even iommu does not work with kdump.
And now have to append crashkernel_low=Y in first kernel to make
kdump work.

We have now modified crashkernel=X to allocate memory beyong 4G (if
available) and do not allocate low range for crashkernel if the user
does not specify that with crashkernel_low=Y.  This causes regression
if iommu is not enabled.  Without iommu, swiotlb needs to be setup in
first 4G and there is no low memory available to second kernel.

Set crashkernel_low automatically if the user does not specify that.

For system that does support IOMMU with kdump properly, user could
specify crashkernel_low=0 to save that 72M low ram.

-v3: add swiotlb_size() according to Konrad.
-v4: add comments what 8M is for according to hpa.
     also update more crashkernel_low= in kernel-parameters.txt
-v5: update changelog according to Vivek.
-v6: Change description about swiotlb referring according to HATAYAMA.

Doug Anderson b81dfaa01f i2c: mux: Add i2c-arb-gpio-challenge 'mux' driver
The i2c-arb-gpio-challenge driver implements an I2C arbitration scheme
where masters need to claim the bus with a GPIO before they can start
a transaction.  This should generally only be used when standard I2C
multimaster isn't appropriate for some reason (errata/bugs).

This driver is based on code that Simon Glass added to the i2c-s3c2410
driver in the Chrome OS kernel 3.4 tree.  The current incarnation as a
mux driver is as suggested by Grant Likely.  See
<https://patchwork.kernel.org/patch/1877311/> for some history.

Frederic Weisbecker c5bfece2d6 nohz: Switch from "extended nohz" to "full nohz" based naming
"Extended nohz" was used as a naming base for the full dynticks
API and Kconfig symbols. It reflects the fact the system tries
to stop the tick in more places than just idle.

But that "extended" name is a bit opaque and vague. Rename it to
"full" makes it clearer what the system tries to do under this
config: try to shutdown the tick anytime it can. The various
constraints that prevent that to happen shouldn't be considered
as fundamental properties of this feature but rather technical
issues that may be solved in the future.

A bunch of changes here, the most interesting one subsystem wise being
 Morimoto-san's work to create snd_soc_component which doesn't do much
 for now but will be pretty important going forwards:
 
  - Add a new component object type which will form the basis of moving
    to a more generic handling of SoC and off-SoC components, contributed
    by Kuninori Morimoto.
  - A fairly large set of cleanups for the dmaengine integration from
    Lars-Peter Clausen, starting to move towards being able to have a
    generic driver based on the library.
  - Performance optimisations to DAPM from Ryo Tsutsui.
  - Support for mixer control sharing in DAPM from Stephen Warren.
  - Multiplatform ARM cleanups from Arnd Bergmann.
  - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

 - Add a new component object type which will form the basis of moving
   to a more generic handling of SoC and off-SoC components, contributed
   by Kuninori Morimoto.
 - A fairly large set of cleanups for the dmaengine integration from
   Lars-Peter Clausen, starting to move towards being able to have a
   generic driver based on the library.
 - Performance optimisations to DAPM from Ryo Tsutsui.
 - Support for mixer control sharing in DAPM from Stephen Warren.
 - Multiplatform ARM cleanups from Arnd Bergmann.
 - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

Bastian Hecht e6a9081055 Input: st1232 - add reset pin handling
We add the possibility to hand over a GPIO number for the reset pin.
This way we can remove existing board code that takes care of it and
group this information properly in the platform data or in the device
tree configuration.

Andy Shevchenko 1b2e98bc1e dma: acpi-dma: introduce ACPI DMA helpers
There is a new generic API to get a DMA channel for a slave device (commit
9a6cecc8 "dmaengine: add helper function to request a slave DMA channel"). In
similar fashion to the DT case (commit aa3da644 "of: Add generic device tree
DMA helpers") we introduce helpers to the DMAC drivers which are enumerated by
ACPI.

The proposed extension provides the following API calls:
	acpi_dma_controller_register(), devm_acpi_dma_controller_register()
	acpi_dma_controller_free(), devm_acpi_dma_controller_free()
	acpi_dma_simple_xlate()
	acpi_dma_request_slave_chan_by_index()
	acpi_dma_request_slave_chan_by_name()

The first two should be used, for example, at probe() and remove() of the
corresponding DMAC driver. At the register stage the DMAC driver supplies a
custom xlate() function to translate a struct dma_spec into struct dma_chan.

Accordingly to the ACPI Fixed DMA resource specification the only two pieces of
information the slave device has are the channel id and the request line (slave
id). Those two are represented by struct dma_spec. The
acpi_dma_request_slave_chan_by_index() provides access to the specifix FixedDMA
resource by its index. Whereas dma_request_slave_channel() takes a string
parameter to identify the DMA resources required by the slave device. To make a
slave device driver work with both DeviceTree and ACPI enumeration a simple
convention is established: "tx" corresponds to the index 0 and "rx" to the
index 1. In case of robust configuration the slave device driver unfortunately
needs to call acpi_dma_request_slave_chan_by_index() directly.

Additionally the patch provides "managed" version of the register/free pair
i.e. devm_acpi_dma_controller_register() and devm_acpi_dma_controller_free().
Usually, the driver uses only devm_acpi_dma_controller_register().

Andy Shevchenko 95019c8c5a dmatest: gather test results in the linked list
The patch provides a storage for the test results in the linked list. The
gathered data could be used after test is done.

The new file 'results' represents gathered data of the in progress test. The
messages collected are printed to the kernel log as well.

Example of output:
	% cat /sys/kernel/debug/dmatest/results
	dma0chan0-copy0: #1: No errors with src_off=0x7bf dst_off=0x8ad len=0x3fea (0)

The message format is unified across the different types of errors. A number in
the parens represents additional information, e.g. error code, error counter,
or status.

Note that the buffer comparison is done in the old way, i.e. data is not
collected and just printed out.

Andy Shevchenko 851b7e16a0 dmatest: run test via debugfs
Instead of doing
	modprobe dmatest ...
	modprobe -r dmatest
we allow user to run tests interactively.

The dmatest could be built as module or inside kernel. Let's consider those
cases.

1. When dmatest is built as a module...

After mounting debugfs and loading the module, the /sys/kernel/debug/dmatest
folder with nodes will be created. They are the same as module parameters with
addition of the 'run' node that controls run and stop phases of the test.

Note that in this case test will not run on load automatically.

Example of usage:
	% echo dma0chan0 > /sys/kernel/debug/dmatest/channel
	% echo 2000 > /sys/kernel/debug/dmatest/timeout
	% echo 1 > /sys/kernel/debug/dmatest/iterations
	% echo 1 > /sys/kernel/debug/dmatest/run

After a while you will start to get messages about current status or error like
in the original code.

Note that running a new test will stop any in progress test.

2. When built-in in the kernel...

The module parameters that is supplied to the kernel command line will be used
for the first performed test. After user gets a control, the test could be
interrupted or re-run with same or different parameters. For the details see
the above section "1. When dmatest is built as a module..."

In both cases the module parameters are used as initial values for the test case.
You always could check them at run-time by running
	% grep -H . /sys/module/dmatest/parameters/*

Because the generic thermal layer can not work without
thermal governors, and it must load the thermal governors

Linus Torvalds 90f340e22c SCSI fixes on 20130412
This is a set of ten bug fixes (and two consisting of copyright year update
 and version number change) pretty much all of which involve either a crash or
 a hang except the removal of the random sleep from the qla2xxx driver (which
 is a coding error so bad, we want it gone before anyone has a chance to copy
 it).

Sebastian Hesselbarth 9abd5f0555 clk: add si5351 i2c common clock driver
This patch adds a common clock driver for Silicon Labs Si5351a/b/c
i2c programmable clock generators. Currently, the driver does not
support VXCO feature of si5351b. Passing platform_data or DT bindings
selectively allows to overwrite stored Si5351 configuration which is
very helpful for clock generators with empty eeprom configuration.
Corresponding device tree binding documentation is also added.

Peter Huewe c61c86dd6e tpm: Add support for new Infineon I2C TPM (SLB 9645 TT 1.2 I2C)
This driver adds support for Infineon's new SLB 9645 TT 1.2 I2C TPMs,
which supports clockstretching, combined reads and a bus speed of
up to 400khz. The device also has a new device id.

The driver works now also fine with device trees, so you can
instantiate your device by adding:
 +       tpm {
 +               compatible = "infineon,slb9645tt";
 +               reg = <0x20>;
 +       };
 for SLB 9645 devices or

 +       tpm {
 +               compatible = "infineon,slb9635tt";
 +               reg = <0x20>;
 +       };
 for SLB 9635 devices

to your device tree.
tpm_i2c_infineon is also retained as a compatible id as a fallback to
slb9635 protocol.

The driver was tested on Beaglebone.

Stephen Warren 4e11f848c6 dt: describe base reset signal binding
This binding is intended to represent the hardware reset signals present
internally in most IC (SoC, FPGA, ...) designs.
It consists of a binding for a reset controller device (provider), and a
pair of properties, "resets" and "reset-names", to link a device node
(consumer) to its reset controller via phandle, similarly to the clock
and interrupt bindings.

The reset controller has all information necessary to reset the consumer
device. That could be provided via device tree, or it could be implemented
in hardware.
The aim is to enable device drivers to request a framework API to issue a
reset simply by providing their struct device pointer as the most common
case.

Instead of open-coding ACPI GPIO resource lookup in each driver, we provide
a helper function analogous to Device Tree version that allows drivers to
specify which GPIO resource they are interested (using an index to the GPIO
resources). The function then finds out the correct resource, translates
the ACPI GPIO number to the corresponding Linux GPIO number and returns
that.

Commit 18a3870 (ACPI / PM: Expose lists of device power resources
to user space) exposed the lists of ACPI power resources associated
with power states of ACPI devices, but it didn't expose the lists
of ACPI wakeup power resources, which also is necessary to get the
full picture of dependencies between ACPI devices and power
resources.

For this reason, for every ACPI device node having a list of ACPI
wakeup power resources associated with it, expose that list to user
space in analogy with commit 18a3870.

This consolidates the two copies and updates the documentation a

Lars Poeschel 97ddb1c88b gpio: mcp23s08: convert driver to DT
This converts the mcp23s08 driver to be able to be used with
device tree.

There is a "spi-present-mask" device tree property, that allows to
use multiple of this spi chips on the same chipselect.

v4:
- removed the ability to specify the pullup from device tree
- updated binding doc

v3:
- removed mcp,chips device tree property in favour of a
    mcp,spi-present-mask and a flag for the pullup of every gpio
- seperated the match table. Now there is one for i2c and one for spi
- do the of reading stuff on stack of the probe function - no devm
    any more

v2:
- squashed booth patches together
- fixed build warning, when CONFIG_OF is not defined
- use of_match_ptr macro for of_match_table

Jon Hunter a2797beadf gpio/omap: force restore if context loss is not detectable
When booting with device-tree the function pointer for detecting context
loss is not populated. Ideally, the pm_runtime framework should be
enhanced to allow a means for reporting context/state loss and we could
avoid populating such function pointers altogether. In the interim until
a generic non-device specific solution is in place, force a restore of
the gpio bank when enabling the gpio controller.

Adds a new device-tree property for the OMAP GPIO controller to indicate
if the GPIO controller is located in a power-domain that never loses
power and hence will always maintain its logic state.

Amit Daniel Kachhap 49d7b5bfb7 cpufreq: exynos: Add cpufreq driver for exynos5440
This patch adds dvfs support for exynos5440 SOC. This soc has 4 cores and
they scale at same frequency. The nature of exynos5440 clock controller is
different from previous exynos controllers so not using the common exynos
cpufreq framework. The major difference being interrupt notification for
frequency change. Also, OPP library is used for device tree parsing to get
different parameters like frequency, voltage etc. Since the opp library sorts
the frequency table in ascending order so they are again re-arranged in
descending order. This will have one-to-one mapping with the clock controller
state management logic.

with feedback on how the workload may respond to frequency change --
memory-bound workloads will not benefit from higher frequency, where
as compute-bound workloads will. This patch enables this "frequency

frequency change decisions by hooking into the powersave bias.

Lukas Czerner 27dd438542 ext4: introduce reserved space
Currently in ENOSPC condition when writing into unwritten space, or
punching a hole, we might need to split the extent and grow extent tree.
However since we can not allocate any new metadata blocks we'll have to
zero out unwritten part of extent or punched out part of extent, or in
the worst case return ENOSPC even though use actually does not allocate
any space.

Also in delalloc path we do reserve metadata and data blocks for the
time we're going to write out, however metadata block reservation is
very tricky especially since we expect that logical connectivity implies
physical connectivity, however that might not be the case and hence we
might end up allocating more metadata blocks than previously reserved.
So in future, metadata reservation checks should be removed since we can
not assure that we do not under reserve.

And this is where reserved space comes into the picture. When mounting
the file system we slice off a little bit of the file system space (2%
or 4096 clusters, whichever is smaller) which can be then used for the
cases mentioned above to prevent costly zeroout, or unexpected ENOSPC.

The number of reserved clusters can be set via sysfs, however it can
never be bigger than number of free clusters in the file system.

Note that this patch fixes the failure of xfstest 274 as expected.

Merge tag 'tegra-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/dt2

From Stephen Warren <swarren@wwwdotorg.org>:

ARM: tegra: device tree changes

This branch contains the majority of the device tree changes for Tegra.
Highlights include:

* Many changes for Tegra114, and the Dalmore board, to enable pinctrl,
  SDHCI/MMC, PWM, DMA, I2C, KBC, SPI, battery, regulators.
* Adding or enabling suspend wakeup sources on many boards, and adding
  suspend timing parameters, to support the system suspend patches.
* Adding clocks to the audio-related nodes, so that in 3.11, the audio
  driver can pull these clocks from device tree rather than hard-coding
  clock names.
* Some small DT fixes/cleanup.

This branch is based on the previous clk pull request.

Arnd Bergmann 2b07910131 ARM: tegra: clock driver development
This branch contains most fixes and enhancements to the Tegra common
 clock driver. The main new feature is a driver for Tegra114, which
 coupled with later device tree changes enables many devices on that
 chip, such as MMC, I2C, etc.
 
 This branch depends on a patch in:
 
 git://git.linaro.org/people/mturquette/linux.git clk-for-3.10
 
 Mike has stated that this branch is stable, and is aware of this
 dependency and merge.
 
 Mike's branch is based on v3.9-rc3, which includes a USB change which
 causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
 this branch pulls in v3.9-rc4 to ensure bisectability as much as
 possible.
 
 This branch is based on v3.9-rc4, followed by a merge of previous Tegra
 "soc" pull request, followed by a merge of clk-for-3.10.

The imx6dl is a derivative of imx6q with very limited difference.  These
two SoCs are so compatible that they can be handled as one platform in
software.  That said, we will not have target SOC_IMX6DL but just
reusing SOC_IMX6Q.   That's why the pinctrl-imx6dl driver is added here
with symbol PINCTRL_IMX6Q controlling the build of it.

Shawn Guo e16415313c pinctrl: imx: move hard-coding data into device tree
Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function.  Every time a new imx SoC support is
added, we need to add such a big mount of data.  With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.

With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.

The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.

As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

Samuel Ortiz e46980a10a mei: bus: Add device enabling and disabling API
It should be left to the drivers to enable and disable the device on the
MEI bus when e.g getting probed.
For drivers to be able to safely call the enable and disable hooks, the
mei_cl_ops must be set before it's probed and thus this should happen
before registering the device on the MEI bus. Hence the mei_cl_add_device()
prototype change.

Javier Martinez Canillas 5dad5ec540 Documentation: dt: gpio-omap: Move interrupt-controller from #interrupt-cells description
The binding documentation for the OMAP GPIO controller has the
"#interrupt-cells" property listed before "#interrupt-controller"
property but its description after.
This is confusing so we move "#interrupt-cells" after the
"interrupt-controller" property so is followed by its description.

While being there, change the properties order to be consistent with
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
and Documentation/devicetree/bindings/gpio/gpio.txt.

According with these docs, the order of the properties for a gpio-omap
device node should be:

    gpio-controller;
    #gpio-cells = <2>;
    interrupt-controller;
    #interrupt-cells = <2>;

Maxime Ripard bc34b5f27c ARM: sunxi: Rework the restart code
The Allwinner sun6i (A31) has a slightly different watchdog, that
doesn't allow to use the already existing restart code.

Rework a bit the restart code to allow to plug in more easily different
restart handlers depending on the device tree.

In the past, we were also meaning sunxi as a generic name covering all
Allwinner SoCs. This won't be true anymore with the A31 (sun6i) that
differs pretty much from sun4i and sun5i, and we will end up having
sunxi, for sun4i and sun5i, and sun6i, which is neither consistent nor
convenient. So, while we're at it, also change sunxi to sun4i.

It was ok at the time of the support of only the A10 and A13 that
looks pretty much the same, but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

Dr. Tilmann Bubeck 393d1d1d76 ext4: implementation of a new ioctl called EXT4_IOC_SWAP_BOOT
Add a new ioctl, EXT4_IOC_SWAP_BOOT which swaps i_blocks and
associated attributes (like i_blocks, i_size, i_flags, ...) from the
specified inode with inode EXT4_BOOT_LOADER_INO (#5). This is
typically used to store a boot loader in a secure part of the
filesystem, where it can't be changed by a normal user by accident.
The data blocks of the previous boot loader will be associated with
the given inode.

This usercode program is a simple example of the usage:

int main(int argc, char *argv[])
{
  int fd;
  int err;

  if ( argc != 2 ) {
    printf("usage: ext4-swap-boot-inode FILE-TO-SWAP\n");
    exit(1);
  }

  fd = open(argv[1], O_WRONLY);
  if ( fd < 0 ) {
    perror("open");
    exit(1);
  }

  err = ioctl(fd, EXT4_IOC_SWAP_BOOT);
  if ( err < 0 ) {
    perror("ioctl");
    exit(1);
  }

  close(fd);
  exit(0);
}

Tomasz Figa 7366b92a77 ARM: Add interface for registering and calling firmware-specific operations
Some boards are running with secure firmware running in TrustZone secure
world, which changes the way some things have to be initialized.

This patch adds an interface for platforms to specify available firmware
operations and call them.

A wrapper macro, call_firmware_op(), checks if the operation is provided
and calls it if so, otherwise returns -ENOSYS to allow fallback to
legacy operation..

By default no operations are provided.

Example of use:

In code using firmware ops:

  __raw_writel(virt_to_phys(exynos4_secondary_startup),
               CPU1_BOOT_REG);

  /* Call Exynos specific smc call */
  if (call_firmware_op(cpu_boot, cpu) == -ENOSYS)
          cpu_boot_legacy(...); /* Try legacy way */

  gic_raise_softirq(cpumask_of(cpu), 1);

In board-/platform-specific code:

  static int platformX_do_idle(void)
  {
          /* tell platformX firmware to enter idle */
          return 0;
  }

  static int platformX_cpu_boot(int i)

This branch is based on zynq/clksrc/cleanup parts because
there are some dependencies on moving timer to generic location.

I could based it on standard Linux tagged version but you will get
several conflicts you will have to resolve.
If you are OK to resolving these problems, please let me know
I will create another branch with core-smp changes which are not based
on zynq/clksrc/cleanup branch.

This patch adds device tree node for the SYSREG registers block
found in Samsung S5P/Exynos SoC series. The SYSREG module
generates control signals for the ARM CPU and various IP blocks
and buses. SYSREG block registers are exposed through APB bus
interface. A sysreg device tree node is to be associated with
mfd syscon driver and all SYSREG clients should use regmap
interface it provides. It allows to eliminate any possible races
and conflicts should different drivers attempt to concurrently

Werner Almesberger 56aa091d60 ieee802154/nl-mac.c: make some MLME operations optional
Check for NULL before calling the following operations from "struct
ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req,
and scan_req.

This fixes a current oops where those functions are called but not
implemented. It also updates the documentation to clarify that they
are now optional by design. If a call to an unimplemented function
is attempted, the kernel returns EOPNOTSUPP via netlink.

The following operations are still required: get_phy, get_pan_id,
get_short_addr, and get_dsn.

Note that the places where this patch changes the initialization
of "ret" should not affect the rest of the code since "ret" was
always set (again) before returning its value.

Antony Pavlov 5b83df2b46 kbuild: fix ld-option function
The kbuild's ld-option function is broken because
the command
  $(CC) /dev/null -c -o "$$TMPO"
does not create object file!

I have used a relatively old mips gcc 3.4.6 cross-compiler
and a relatively new gcc 4.7.2 to check this fact
but the results are the same.

EXAMPLE:
  $ rm /tmp/1.o
  $ mips-linux-gcc /dev/null -c -o /tmp/1.o
  mips-linux-gcc: /dev/null: linker input file unused because linking not done
  $ ls -la /tmp/1.o
  ls: cannot access /tmp/1.o: No such file or directory

We can easily fix the problem by adding
the '-x c' compiler option.

EXAMPLE:
  $ rm /tmp/1.o
  $ mips-linux-gcc -x c /dev/null -c -o /tmp/1.o
  $ ls -la /tmp/1.o
  -rw-r--r-- 1 antony antony 778 Apr  2 20:40 /tmp/1.o

Instead of using a custom binding for retrieving the GPIO that activates the
LCD from devicetree, use a standard regulator.

This approach has the advantage to be more generic.

For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.

Lars-Peter Clausen 51c2a4871c hwmon: (adt7410) Add support for the adt7310/adt7320
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.

The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.

- APB DMA based transfer for larger transfer i.e. more than FIFO depth.
- Clock gating through runtime PM callbacks.

special cases.

The GRLIB core operates in cpu mode. The number of bits per word might be
limited. There might be native chipselects selected via a slave select
register. These differences to the FSL type cores, if present, are indicated by
a capabilities register. Other register and function differences exists but are

Greg Kroah-Hartman 64dc9e2e73 usb: patches for v3.10 merge window
Here is the big Gadget & PHY pull request. Many of us have
 been really busy lately getting multiple drivers to a better
 position.
 
 Since this pull request is so large, I will divide it in sections
 so it's easier to grasp what's included.
 
 - cleanups:
 	. UDC drivers no longer touch gadget->dev, that's now udc-core
 		responsibility
 	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
 	. UDC drivers no longer initialize DMA-related fields from gadget's
 		device structure
 	. UDC drivers don't touch gadget.dev.driver directly
 	. UDC drivers don't assign gadget.dev.release directly
 	. Removal of some unused DMA_ADDR_INVALID
 	. Introduction of CONFIG_USB_PHY
 	. All phy drivers have been moved to drivers/usb/phy and renamed to
 		a common naming scheme
 	. Fix PHY layer so it never returns a NULL pointer, also fix all
 		callers to avoid using IS_ERR_OR_NULL()
 	. Sparse fixes all over the place
 	. drivers/usb/otg/ has been deleted
 	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
 		usage
 
 - new features:
 	. UDC core now provides a generic way for tracking and reporting
 		UDC's state (not attached, resuming, suspended, addressed,
 		default, etc)
 	. twl4030-usb learned that it shouldn't be enabled during init
 	. Full DT support for DWC3 has been implemented
 	. ab8500-usb learned about pinctrl framework
 	. nop PHY learned about DeviceTree and regulators
 	. DWC3 learned about suspend/resume
 	. DWC3 can now be compiled in host-only and gadget-only (as well as
 		DRD) configurations
 	. UVC now enables streaming endpoint based on negotiated speed
 	. isp1301 now implements the PHY API properly
 	. configfs-based interface for gadget drivers which will lead to
 		the removal of all code which just combines functions together
 		to build functional gadget drivers.
 	. f_serial and f_obex were converted to new configfs interface while
 		maintaining old interface around.
 
 - non-critical fixes:
 	. UVC gadget driver got fixes for Endpoint usage and stream calculation
 	. ab8500-usb fixed unbalanced clock and regulator API usage
 	. twl4030-usb got a fix for when OMAP3 is booted with cable connected
 	. fusb300_udc got a fix for DMA usage
 	. UVC got fixes for two assertions of the USB Video Class Compliance
 		specification revision 1.1
 	. build warning issues caused by recent addition of __must_check to
 		regulator API
 
 These are all changes which deserve a mention, all other changes are related
 to these one or minor spelling fixes and other similar tasks.

Merge tag 'usb-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

Felipe writes:

usb: patches for v3.10 merge window

Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.

Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.

- cleanups:
	. UDC drivers no longer touch gadget->dev, that's now udc-core
		responsibility
	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
	. UDC drivers no longer initialize DMA-related fields from gadget's
		device structure
	. UDC drivers don't touch gadget.dev.driver directly
	. UDC drivers don't assign gadget.dev.release directly
	. Removal of some unused DMA_ADDR_INVALID
	. Introduction of CONFIG_USB_PHY
	. All phy drivers have been moved to drivers/usb/phy and renamed to
		a common naming scheme
	. Fix PHY layer so it never returns a NULL pointer, also fix all
		callers to avoid using IS_ERR_OR_NULL()
	. Sparse fixes all over the place
	. drivers/usb/otg/ has been deleted
	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
		usage

- new features:
	. UDC core now provides a generic way for tracking and reporting
		UDC's state (not attached, resuming, suspended, addressed,
		default, etc)
	. twl4030-usb learned that it shouldn't be enabled during init
	. Full DT support for DWC3 has been implemented
	. ab8500-usb learned about pinctrl framework
	. nop PHY learned about DeviceTree and regulators
	. DWC3 learned about suspend/resume
	. DWC3 can now be compiled in host-only and gadget-only (as well as
		DRD) configurations
	. UVC now enables streaming endpoint based on negotiated speed
	. isp1301 now implements the PHY API properly
	. configfs-based interface for gadget drivers which will lead to
		the removal of all code which just combines functions together
		to build functional gadget drivers.
	. f_serial and f_obex were converted to new configfs interface while
		maintaining old interface around.

- non-critical fixes:
	. UVC gadget driver got fixes for Endpoint usage and stream calculation
	. ab8500-usb fixed unbalanced clock and regulator API usage
	. twl4030-usb got a fix for when OMAP3 is booted with cable connected
	. fusb300_udc got a fix for DMA usage
	. UVC got fixes for two assertions of the USB Video Class Compliance
		specification revision 1.1
	. build warning issues caused by recent addition of __must_check to
		regulator API

These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

The 'camera' DT node needs to have sclk_cam0/1 and pxl_async0/1 clocks
specified, while 'fimc' nodes should have only "fimc" and "sclk_fimc".
"mux" and "parent" are leftovers from early versions of patches adding
DT support, when the IP bus clock parent clock was being set by the
driver. A better solution is needed to have e.g. clocks driver setting
all required parent clocks, before clock consumers start using the
clocks. Currently this binding doesn't describe parent clocks setup,
it needs to be specified and handled somewhere else.

Takashi Iwai 8fc24426f1 Revert "ALSA: hda - Allow power_save_controller option override DCAPS"
This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

Tony Prisk 7ab0a48420 video: fb: vt8500: Convert framebuffer drivers to standardized binding
Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.

This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.

There are two side-effects of making this conversion:

1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.

2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.

I have also taken the opportunity to alphabetise the includes of each
driver to avoid double-ups.

Jon Hunter 32cde0b514 ARM: OMAP2+: Convert ONENAND to retrieve GPMC settings from DT
When booting with device-tree, retrieve GPMC settings for ONENAND from
the device-tree blob. This will allow us to remove all static settings
stored in the gpmc-nand.c in the future once the migration to
device-tree is complete.

The user must now specify the ONENAND device width in the device-tree
binding so that the GPMC can be programmed correctly. Therefore, update
the device-tree binding documentation for ONENAND devices connected to
the GPMC to reflect this.

Please note that this does not include GPMC timings for ONENAND. The
timings are being calculated at runtime.

There is some legacy code that only enables read wait monitoring for
non-OMAP3 devices. There are no known OMAP3 device issues that prevent
this feature being enabled and so when booting with device-tree use the
wait-monitoring settings described in the device-tree blob.

Jon Hunter d36b4cd46d ARM: OMAP2+: Add additional GPMC timing parameters
Some of the GPMC timings parameters are currently missing from the GPMC
device-tree binding. Add these parameters to the binding documentation
as well as code to read them. Also add either "-ps" or "-ns" suffix to
the GPMC timing properties to indicate whether the timing is in
picoseconds or nanoseconds.

The existing code in gpmc_read_timings_dt() is checking the value of
of_property_read_u32() and only is successful storing the value read
in the gpmc_timings structure. Checking the return value in this case
is not necessary and we can simply read the value, if present, and
store directly in the gpmc_timings structure. Therefore, simplify the
code by removing these checks.

The comment in the gpmc_read_timings_dt() function, "only for OMAP3430"
is also incorrect as it is applicable to all OMAP3+ devices. So correct
this too.

Frederic Weisbecker 3451d0243c nohz: Rename CONFIG_NO_HZ to CONFIG_NO_HZ_COMMON
We are planning to convert the dynticks Kconfig options layout
into a choice menu. The user must be able to easily pick
any of the following implementations: constant periodic tick,
idle dynticks, full dynticks.

As this implies a mutual exclusion, the two dynticks implementions
need to converge on the selection of a common Kconfig option in order
to ease the sharing of a common infrastructure.

It would thus seem pretty natural to reuse CONFIG_NO_HZ to
that end. It already implements all the idle dynticks code
and the full dynticks depends on all that code for now.
So ideally the choice menu would propose CONFIG_NO_HZ_IDLE and
CONFIG_NO_HZ_EXTENDED then both would select CONFIG_NO_HZ.

On the other hand we want to stay backward compatible: if
CONFIG_NO_HZ is set in an older config file, we want to
enable CONFIG_NO_HZ_IDLE by default.

But we can't afford both at the same time or we run into
a circular dependency:

1) CONFIG_NO_HZ_IDLE and CONFIG_NO_HZ_EXTENDED both select
   CONFIG_NO_HZ
2) If CONFIG_NO_HZ is set, we default to CONFIG_NO_HZ_IDLE

We might be able to support that from Kconfig/Kbuild but it
may not be wise to introduce such a confusing behaviour.

So to solve this, create a new CONFIG_NO_HZ_COMMON option
which gathers the common code between idle and full dynticks
(that common code for now is simply the idle dynticks code)
and select it from their referring Kconfig.

Then we'll later create CONFIG_NO_HZ_IDLE and map CONFIG_NO_HZ
to it for backward compatibility.
