Peter Ujfalusi 11e38e11af mfd: twl6040: Select i2c fast mode as default with regmap patch
All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's
defaults to normal mode (100KHz). So far twl6040 has no problem with i2c
communication in this configuration it is safer to select fast i2c mode.

Peter Ujfalusi 02d02728ea mfd: twl6040: Clear the interrupt ID register before requesting IRQ
If for some reason the boot loader enabled the audpwron GPIO we will have
pending IRQs to be handled. This seams to break twl6040 for some reason
leading to non working i2c communication (i2c timeouts). Clearing the INTID
register after we requested the audpwron GPIO (and set it to low) will
ensure that the chip will operate normally in this case as well.

Charles Keepax d137be00ee mfd: core: Don't use devres functions before device is added
The supply aliases for the MFD devices were being added using devres but
the device hasn't been added at this point and as such we can't use
devres.

The MFD already has a function that removes devices this patch uses the
non-devres versions of the supply alias functions and adds an unregister
in mfd_remove_devices_fn.

Krzysztof Kozlowski e349c910e2 mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsets
The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.

The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.

Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

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 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.

symbols: MAX14577_REG_INVALID and max14577_irq_source.

Doug Anderson c42ba72ec3 mfd: tps65090: Stop caching most registers
Nearly all of the registers in tps65090 combine control bits and
status bits.  Turn off caching of all registers except the select few
that can be cached.

In order to avoid adding more duplicate #defines, we also move some
register offset definitions to the mfd driver (and resolve
inconsistent names).

Doug Anderson 7d811771c9 mfd: tps65090: Don't tell child devices we have an IRQ if we don't
If we weren't given an interrupt we shouldn't tell child devices (like
the tps65090 charger) that they have an interrupt.  This is needed so
that we can support polling mode in the tps65090 charger driver.

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.

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.

Krzysztof Kozlowski 5a78401623 mfd: sec-core: Fix uninitialized 'regmap_rtc' on S2MPA01
Initialize the 'regmap_rtc' on S2MPA01 to some sane value. Sane at least
for S5M87X chipsets, not S2MPS/S2MPA but it won't be used because
rtc-s5m driver does not support S2MPA01.

This fixes following error:
drivers/mfd/sec-core.c:342:45: warning: ‘regmap_rtc’ may be used uninitialized in this function [-Wuninitialized]

Krzysztof Kozlowski 742766aac5 mfd: tps65910: Fix regmap_irq_chip_data leak on mfd_add_devices fail
The tps65910_i2c_probe() allocates regmap_irq_chip in
tps65910_irq_init() but it does not clean this up in case of
mfd_add_devices() failure.

Krzysztof Kozlowski 483e2dfdbc mfd: tps65910: Fix possible invalid pointer dereference on regmap_add_irq_chip fail
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.
