Linus Torvalds c913fc4146 ARM: SoC: late DT updates for v4.9
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

Fabian Frederick bd721ea73e treewide: replace obsolete _refok by __ref
There was only one use of __initdata_refok and __exit_refok

__init_refok was used 46 times against 82 for __ref.

Those definitions are obsolete since commit 312b1485fb ("Introduce new
section reference annotations tags: __ref, __refdata, __refconst")

This patch removes the following compatibility definitions and replaces
them treewide.

/* compatibility defines */
#define __init_refok     __ref
#define __initdata_refok __refdata
#define __exit_refok     __ref

I can also provide separate patches if necessary.
(One patch per tree and check in 1 month or 2 to remove old definitions)

A new Kconfig option is added, CONFIG_INTEGRATOR_AP_TIMER and is selected

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Masahiro Yamada e324654294 ARM: use "depends on" for SoC configs instead of "if" after prompt
Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

    config ARCH_FOO
            bool "Foo SoCs" if ARCH_MULTI_V7

and

    config ARCH_FOO
            bool "Foo SoCs"
            depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7.  So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns.  This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing.  (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
 the discussion that followed, but I can see value in being consistent
 and in making the lines shorter]

the SP804 timers and uses the same for initialising the timers to
known(off) state, thereby removing the dependency on the header
asm/hardware/arm_timer.h

This change is in prepartion to move sp804 timer support out of arch/arm
so that it can be used on ARM64 platforms.

Rob Herring 61dc485b90 ARM: integrator: Convert PCI to use generic config accessors
Convert the integrator PCI driver to use the generic config access
functions.

This changes accesses from __raw_readX/__raw_writeX to readX/writeX
variants.  The spinlock is removed because it is unnecessary.  The config
read and write functions are already protected with a spinlock and no
access can occur during the .pre_init function.

Linus Walleij f956a785a2 soc: move SoC driver for the ARM Integrator
This creates a new SoC bus driver for the ARM Integrator
family core modules to register the SoC bus and provide
sysfs info for the core module. We delete the corresponding
code from the Integrator machine and select this driver to
get a clean result.

Using the augmented reset driver for the Versatile family,
we can move the reset handling for the Integrator out of the
machine. We add a "syscon" attribute to the core module, and
access the syscon registers using this handle. We need to
select SYSCON, POWER, POWER_RESET and POWER_RESET_VERSATILE
in order for the restart functionality to always be
available on all systems (it should not be optional).

Liviu Dudau 0b0b0893d4 of/pci: Fix the conversion of IO ranges into IO resources
The ranges property for a host bridge controller in DT describes the
mapping between the PCI bus address and the CPU physical address.  The
resources framework however expects that the IO resources start at a pseudo
"port" address 0 (zero) and have a maximum size of IO_SPACE_LIMIT.  The
conversion from PCI ranges to resources failed to take that into account,
returning a CPU physical address instead of a port number.

Also fix all the drivers that depend on the old behaviour by fetching the
CPU physical address based on the port number where it is being needed.

Linus Torvalds b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

Linus Walleij 11c32d7b62 video: move Versatile CLCD helpers
This moves the Versatile-specific helper code and panel database
down into the drivers/video folder next to the CLCD driver
itself, preserving the config symbol but also moving the header
to platform data.

This is necessary to rid the Integrator of this final <plat/*>
inclusion dependency and get us one less user of the
plat-versatile folder.

Linus Walleij e6dc195c1c ARM: integrator: get rid of <mach/memory.h>
The Integrator has a custom <mach/memory.h> header defining the
BUS_OFFSET for *_to_bus and bus_to_* operations as offset from
0x80000000.

This switches the Integrator over to using the mechanism
introduced for the Keystone to provide the same offset using
the device tree, deletes <mach/memory.h> and augments the
Integrator device tree to provide the bus offset.

Linus Walleij 11f9323a48 ARM: integrator: fix OF-related regression
Commit 07e461cd7e
"of: Ensure unique names without sacrificing determinism"
caused a boot failure regression on the Integrator machines.

The problem is probably caused by fiddling too much with
the device tree population in the OF init function, such
as passing the SoC bus device as parent when populating
the device tree.

This patch fixes the problem by:

- Avoiding to explicitly look up the tree root
- Look up devices needed before device population from
  the match only, passing NULL as root
- Passing NULL as root and parent when calling
  of_platform_populate()

After this the Integrators boot again. Tested on
Integrator/AP and Integrator/CP.

Linus Walleij e1318391fd ARM: integrator: fix section mismatch problem
This addresses a section mismatch problem in the IM-PD1
driver in the Integrator/AP.

The IM-PD1 contains a VIC interrupt controller and therefore
the driver calls vic_init_cascaded() which is marked __init as
irqchips are simply not hot-pluggable and specifically the VIC
is assumed to initiate only on boot.

However the module driver model of the Integrator LM bus
assumes that logic tile drivers can be probed at runtime. This
is not really the case for IM-PD1: these tiles are detected at
boot and they cannot be plugged into a running system. Before
this patch it is of course possible to modprobe them later.

By first forcing the IM-PD1 to bool we make sure this driver
gets compiled into the kernel, and we know it will be probed
only at boot time when the tiles are detected, so we can tag
its probe function __init_refok as we know it won't be called
after boot now, and the section mismatch problem goes away.

As a side effect, sysfs binding from userspace becomes
impossible, so we tag the driver to suppress the bind/unbind
sysfs attributes.

Merge tag 'fixes-non-critical-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC non-critical bug fixes from Arnd Bergmann:
 "Lots of isolated bug fixes that were not found to be important enough
  to be submitted before the merge window or backported into stable
  kernels.

  The vast majority of these came out of Arnd's randconfig testing and
  just prevents running into build-time bugs in configurations that we
  do not care about in practice"

Arnd Bergmann 152c55553e ARM: integrator: only select pl01x if TTY is enabled
Building the integrator platform without TTY support currently
results in a build failure because we always turn on the
pl010 or pl011 drivers. Changing this to a conditional 'select'
statement enables us to build more random configurations, although
it should have little impact for practical configurations.

Linus Walleij a79528e9d8 ARM: integrator: register sched_clock directly
The detour through plat-versatile/sched-clock.c is hard to migrate
to multiplatform set-up and it's very little code being duplicated
so let's just inline the sched_clock registration and cut one more
dependency to plat-versatile.

This also makes this sched_clock implementation compulsory.

Olof Johansson 11d73c56b9 This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
 387798b (ARM: initial multiplatform support).)
 
 To make this work some code out of arch/arm needed to be adapted. The
 respective changes got acks by their maintainers to be taken via armsoc
 (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
 
 Compared to the previous pull request there was another patch added that
 fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
 squash this fix into the original commit to save him from the need to
 reverify the series.

Linus Walleij 29525484cd ARM: integrator: select GPIO block
The Integrator/AP can be used with a logic module called
IM-PD1, which contains a few AMBA PrimeCell devices, one of which
is the PL061 GPIO controller. As the lines from this GPIO
controller are looped back to devices on the board itself and
provides resources back to it, we need to always have GPIO
and the PL061 driver available for other devices to work.
