Stratos Karafotis fdb56c45a2 mfd: db8500-prcmu: Use cpufreq_for_each_entry macro for iteration
The cpufreq core now supports the cpufreq_for_each_entry macro helper
for iteration over the cpufreq_frequency_table, so use it.

It should have no functional changes.

Tony Lindgren a613b739b8 mfd: twl-core: Fix idle mode signaling for omaps when booted with device tree
I noticed a regression where the omap sys_clkreq signal will never
trigger for omap3 when booted with device tree while it triggers
when booted in legacy mode. This means voltage scaling does not
do anything when booted with device tree.

Turns out the reason is we fail to initialize the SmartReflex
enable bit in twl4030 with the following error:

twl: not initialized

And that happens because we are wrongly tinkering with the twl4030
registers in arch/arm/mach-omap2/omap_twl.c before the driver is
initialized. Looking at the the SmartReflex bit enable code in
omap_twl.c, we need to always set it.

So let's fix the issue by always enabling the twl4030 SmartReflex
bit in the drivers/mfd/twl-core.c probe, and drop the related
code in omap_twl.c.

Note that we still have some twl4030 tinkering left in omap_twl.c
for the twl6030 case, but that's a different patch.

Krzysztof Kozlowski 4706a5253b extcon: max14577: Add support for MAX77836
Add support for MAX77836 chipset to the max14577 extcon driver. The
MAX77836 MUIC has additional interrupts (VIDRM, ADC1K) so IRQ handling
is split up into two functions: max14577_parse_irq() and
max77836_parse_irq().

Krzysztof Kozlowski aee2a57c74 mfd: max77836: Add MAX77836 support to max14577 driver
Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.

The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.

The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.

Since we have two regmap_irq_chip, use shared interrupts on MAX77836.

This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.

This patch continues the preparation for adding support for MAX77836
device to existing max14577 driver.

Add enum for types of devices supported by this driver. The device type

Linus Torvalds f83ccb9358 ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support
 for new SoCs, boards and devices without changing kernel source. The plan
 is still to move the devicetree files out of the kernel tree and reduce
 the amount of churn going on here, but we keep finding reasons to delay
 doing that.
 
 Changes are really all over the place, with little sticking out particularly.
 We have contributions from a total of 116 people in this branch.
 
 Unfortunately, the size of this branch also causes a significant number
 of conflicts at the moment, typically when subsystem maintainers merge
 patches that change the driver at the same time as the dts files. In
 most cases this could be avoided because the dts changes are supposed
 to be compatible in both ways, and we are asking everyone to send ARM
 dts changes through our tree only.

Linus Torvalds 3786075b5e regulator: Updates for v3.15
This release has lots and lots of small cleanups and fixes in the
 regulator subsystem, mainly cleaning up some bad patterns that got
 duplicated in DT code, but otherwise very little of note outside
 of the scope of the relevant drivers:
 
  - Support for configuration of the initial state for gpio regulators
    with multi-voltage support.
  - Support for calling regulator_set_voltage() on fixed regulators.
  - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung S2MPA01 &
    S2MPS11/4, some PWM controlled regulators found on some ST boards and
    TI TPS65218.

Guenter Roeck 204747c970 mfd: kempld-core: Fix potential hang-up during boot
On PXT and COMe-cPC2 boards it is observed that the hardware
mutex is acquired but not being released during initialization.
This can result in a hang-up during boot if the driver is built
into the kernel.

Releasing the mutex twice if it was acquired fixes the problem.
Subsequent request/release cycles work as expected, so the fix is
only needed during initialization.

Fixes: 4aab3fadad ("mfd: tps65910: Move interrupt implementation code to mfd file")

tps65910_irq_init() sets 'tps65910->chip_irq' before calling
regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in
memory allocation of regmap_irq_chip_data members then:

1. The 'tps65910->chip_irq' will still hold some value
2. 'tps65910->irq_data' will be pointing to already freed memory
   (because regmap_add_irq_chip() will free it on error)

This results in invalid memory access during driver remove because the
tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

Peter Tyser eb71d4dec4 mfd: lpc_ich: Add support for iTCO v3
Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
register layouts for the iTCO than the current v1 and v2 iTCO.
Differences from previous iTCO versions include:
- The ACPI space is enabled in the "ACPI base address" register instead
  of the "ACPI control register"

- The "no reboot" functionality is set in the "Power Management
  Configuration" register instead of the "General Control and Status"
  (GCS) register or PCI configuration space.

- The "ACPI Control Register" is not present on v3.  The "Power
  Management Configuration Base Address" register resides at the same
  address is Avoton/Bay Trail.

To differentiate these newer chipsets create a new v3 iTCO version and
update the MFD driver to support them.

driver that uses it right now (pm8921) so that it's always compiled when
needed. In the future we can rename pm8921-core.c to something
more generic.

Linus Walleij f864c46aae mfd: dbx500/abx500: root out hardcoded IRQ assignments
The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.

Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

Charles Keepax 1c18d2ca10 mfd: arizona: Use new regmap features for manual register patch
On the wm5102 the register patches are applied manually, rather than by
the regmap core. This application is wrapped in calls to
regcache_cache_bypass. However, this is dangerous as other threads may
be accessing the hardware at the same time as the pm_runtime operations
and if they do so during the period whilst cache_bypass is enabled those
writes will miss the cache when they shouldn't.

Apply the register patch using the new regmap_multi_reg_write_bypassed
function to avoid this problem. Also remove the call to
regcache_cache_bypass from the hardware patch application as it is
unneeded there and creates a similar window for writes to miss the
cache.

Add support for non-blocking request, pre_req() runs dma_map_sg() and
post_req() runs dma_unmap_sg(). This patch can increase card read/write
speed, especially for high speed card and slow CPU(for some embedded

Users can get a great benefit from this patch. if CPU frequency is 800MHz,
SDR104 or DDR50 card read/write speed may increase more than 15%.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.

It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

Stephen Warren a7c42b2545 mfd: Always assign of_node in mfd_add_device()
mfd_add_device() assigns .of_node in the device objects it creates only
if the mfd_cell for the device has the .of_compatible field set and the
DT node for the top-level MFD device contains a child whose compatible
property matches the cell's .of_compatible field.

This leaves .of_node unset in many cases. When this happens, entries in
the DT /aliases property which refer to the top-level MFD DT node will
never match the MFD child devices, hence causing the requested alias not
to be honored.

Solve this by setting each MFD child device's .of_node equal to the top-
level MFD device's .of_node field in the cases where it would otherwise
remain unset.

The first use-case for this will be aliases for the TPS6586x's RTC
device.

Milo Kim 470eca47bd mfd: Add LP3943 MFD driver
LP3943 has 16 output pins which can be used as GPIO expander and PWM generator.

* Regmap I2C interface for R/W LP3943 registers

* Atomic operations for output pin assignment
  The driver should check whether requested pin is available or not.
  If the pin is already used, pin request returns as a failure.
  A driver data, 'pin_used' is checked when gpio_request() and
  pwm_request() are called. If the pin is available, then pin_used is set.
  And it is cleared when gpio_free() and pwm_free().

* Device tree support
  Compatible strings for GPIO and PWM driver.
  LP3943 platform data is PWM related, so parsing the device tree is
  implemented in the PWM driver.

Add PM suspend/resume ops to the sec MFD core driver and make it a wake
up source. This allows proper waking from suspend to RAM and also fixes
broken interrupts after resuming:
[   42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5

Interrupts stop working after first resume initiated by them (e.g. by
RTC Alarm interrupt) because interrupt registers were not cleared properly.

When device is woken up from suspend by RTC Alarm, an interrupt occurs
before resuming I2C bus controller. The interrupt is handled by
regmap_irq_thread which tries to read RTC registers. This read fails
(I2C is still suspended) and RTC Alarm interrupt is disabled.

Disable the S5M8767 interrupts during suspend (disable_irq()) and enable
them during resume so the device will be still woken up but the interrupt
won't happen before resuming I2C bus.

the register need to be monitored. With the twl_set_regcache_bypass() the
client driver can switch regcache bypass on and off when it is needed so

Sebastian Andrzej Siewior 7ca6740cd1 mfd: input: iio: ti_amm335x: Rework TSC/ADC synchronization
The ADC driver always programs all possible ADC values and discards
them except for the value IIO asked for. On the am335x-evm the driver
programs four values and it takes 500us to gather them. Reducing the number
of conversations down to the (required) one also reduces the busy loop down
to 125us.

This leads to another error, namely the FIFOCOUNT register is sometimes
(like one out of 10 attempts) not updated in time leading to EBUSY.
The next read has the FIFOCOUNT register updated.
Checking for the ADCSTAT register for being idle isn't a good choice either.
The problem is that if TSC is used at the same time, the HW completes the
conversation for ADC *and* before the driver noticed it, the HW begins to
perform a TSC conversation and so the driver never seen the HW idle. The
next time we would have two values in the FIFO but since the driver reads
everything we always see the current one.
So instead of polling for the IDLE bit in ADCStatus register, we should
check the FIFOCOUNT register. It should be one instead of zero because we
request one value.

This change in turn leads to another error. Sometimes if TSC & ADC are
used together the TSC starts generating interrupts even if nobody
actually touched the touchscreen. The interrupts seem valid because TSC's
FIFO is filled with values for each channel of the TSC. This condition stops
after a few ADC reads but will occur again. Not good.

On top of this (even without the changes I just mentioned) there is a ADC
& TSC lockup condition which was reported to me by Jeff Lance including the
following test case:
A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw"
and a mug on touch screen. With this setup, the hardware will lockup after
something between 20 minutes and it could take up to a couple of hours.
During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means
STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is
idle and busy at the same time which is an invalid condition.

For all this reasons I decided to rework this TSC/ADC part and add a
handshake / synchronization here:
First the ADC signals that it needs the HW and writes a 0 mask into the
SE register. The HW (if active) will complete the current conversation
and become idle. The TSC driver will gather the values from the FIFO
(woken up by an interrupt) and won't "enable" another conversation.
Instead it will wake up the ADC driver which is already waiting. The ADC
driver will start "its" conversation and once it is done, it will
enable the TSC steps so the TSC will work again.

After this rework I haven't observed the lockup so far. Plus the busy
loop has been reduced from 500us to 125us.

The continues-read mode remains unchanged.

Sebastian Andrzej Siewior 7e170c6e4f mfd: ti_am335x_tscadc: Don't read back REG_SE
The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.

The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap

Remove sec_reg* helpers as they are not used anymore. These helpers were
error-prone as they mixed u8 with unsigned int and they changed order of

Also the helpers didn't give any way of useful abstraction as they just
called corresponding regmap function.

Krzysztof Kozlowski 3e1e4a5f3a mfd/rtc: s5m: fix register updating by adding regmap for RTC
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.

On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC.  This could be observed in various hangs,
e.g.  in infinite loop during waiting for UDR field change.

On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Linus Torvalds db0b2d0116 For the 3.13 merge window we have a couple of new drivers for the AMS
AS3722 PMIC and for STMicroelectronics STw481x PMIC.
 
 Although this is a smaller update than usual, we also have:
 
 - Device tree support for the max77693 driver.
 
 - linux/of.h inclusion for all DT compatible MFD drivers, to avoid build
   breakage in the future.
 
 - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver.
 
 - A small arizona update for new wm5110 DSP registers and a few fixes.
 
 - A small palmas update as well, including an of_device table addition
   and a few minor fixes.
 
 - Two small mfd-core changes, one including a memory leak fix for when
   mfd_add_device() fails.
 
 - Our usual round of minor cleanups and janitorial fixes.

Pull MFD updates from Samuel Ortiz:
 "For the 3.13 merge window we have a couple of new drivers for the AMS
  AS3722 PMIC and for STMicroelectronics STw481x PMIC.

  Although this is a smaller update than usual, we also have:

   - Device tree support for the max77693 driver

   - linux/of.h inclusion for all DT compatible MFD drivers, to avoid
     build breakage in the future

   - Support for Intel Wildcat Point-LP PCH through the lpc_ich driver

   - A small arizona update for new wm5110 DSP registers and a few fixes

   - A small palmas update as well, including an of_device table
     addition and a few minor fixes

   - Two small mfd-core changes, one including a memory leak fix for
     when mfd_add_device() fails

   - Our usual round of minor cleanups and janitorial fixes"

There are no too intrusive changes in this update batch.  The biggest
 LOC is found in the new DICE driver, and other small changes are
 scattered over the whole sound subtree (which is a common pattern).
 
 Below are highlights:
 
 - ALSA core:
   * Memory allocation support with genpool
   * Fix blocking in drain ioctl of compress_offload
 
 - HD-audio:
   * Improved AMD HDMI supports
   * Intel HDMI detection improvements
   * thinkpad_acpi mute-key integration
   * New PCI ID, New ALC255,285,293 codecs, CX20952
 
 - USB-audio:
   * New buffer size management
   * Clean up endpoint handling codes
 
 - ASoC:
   * Further work on the dmaengine helpers, including support for
     configuring the parameters for DMA by reading the capabilities of
     the DMA controller which removes some guesswork and magic numbers
     from drivers.
   * A refresh of the documentation.
   * Conversions of many drivers to direct regmap API usage in order to
     allow the ASoC level register I/O code to be removed, this will
     hopefully be completed by v3.14.
   * Support for using async register I/O in DAPM, reducing the time
     taken to implement power transitions on systems that support it.

Linus Torvalds c6d65bf246 regulator: Updates for v3.13
Lots of driver updates here plus some nice new core features, the main
 one being the first:
 
  - Enable support for providing a dummy regulator when we know that one
    must exist for the device to be functional.  This makes it much
    easier to add regulator support to drivers since we don't require
    that the machine integration for all systems using the device be
    updated to provide regulators.
  - Substantial reduction in the amount of busy waiting done while
    waiting for enables to complete.
  - Allow MFDs to distribute regulator supplies to child devices so we
    don't have to expose the internal structure of MFDs outside of the
    driver.
  - Managed registeration for regulators.

Geert Uytterhoeven 0b208e41ac mfd: Fix memory leak in mfd_add_devices()
If the first call to mfd_add_device() fails, no child devices have been
registered to the parent yet, and thus mfd_remove_devices() won't find
anything to remove nor free.
Hence the previously allocated array of atomic_t objects will leak.

Free the array instead of calling mfd_remove_devices() on failure during
the first loop iteration to fix this.

Geert Uytterhoeven 03e361b25e mfd: Stop setting refcounting pointers in original mfd_cell arrays
Commit 1e29af62f2 ("mfd: Add refcounting
support to mfd_cells") had to drop the "const" keyword on the "cell"
parameter of mfd_add_devices(), as it added the refcounting pointers
to the objects of the passed mfd_cell array itself.

However, the mfd core code operates on copies of the mfd_cell objects,
so there's no need to modify the originally passed objects.

Hence, move the setting of the refcounting pointers from mfd_add_devices()
to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made.
mfd_clone_cell() can just pass (a copy of) the original usage_count
pointer.

This allows to make the "cell" parameter of mfd_add_devices() "const"
again, and avoids future race conditions when registering multiple
instances of the same device in parallel.
