6fd7f2bbd4 mfd / platform: cros_ec: Move device sysfs attributes to its own driver
The entire way how cros debugfs attibutes are created is broken.
cros_ec_sysfs should be its own driver and its attributes should be
associated with the sysfs driver not the mfd driver.

The patch also adds the sysfs documentation.

6377cfa3b8 mfd: stmpe: Preparations for STMPE ADC driver
This prepares the MFD for the STMPE ADC driver. This commit introduces
devicetree settings that are used by the ADC and adds an init function.
Common ADC settings that are shared with the touchscreen driver can now
reside in the overlying MFD.

628f3dfe4c mfd: at91-usart: Add platform dependency
It doesn't make sense to present option MFD_AT91_USART by default if
not building an AT91 kernel, as the drivers which depend on it are
not available.

eef0594aee mfd: sec-core: Allow building as module
The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module.  The dependent clock,
regulator and RTC drivers already can be built as a module.

Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.

This also add required module authors to sec-irq.c file based on recent
main contributors.

others (LPC) living in drivers/platform. The transport drivers are more
platform specific. So, move the I2C and SPI transport drivers to the

The driver is based on the original work by Intel, found at:
  https://github.com/01org/ProductionKernelQuilts

This is a minimal version for adding the basic resources.  Currently,
only ACPI PMIC opregion and the external power-button are used.

intel_soc_pmic_config_cht_crc based on this.

This fixes the Bay Trail specific ACPI OpRegion code causing problems
on Cherry Trail devices. Specifically this was causing the external
microsd slot on a Dell Venue 8 5855 (Cherry Trail version) to not work
and the eMMC to become unreliable and throw lots of errors.

The PMIC provides ACPI OpRegions which must be available for other

Somehow its Kconfig option ended up being a tristate though, this fixes

aaac4a2ead mfd: axp20x-i2c: Document that this must be builtin on x86
On x86 the AXP288 PMIC provides an ACPI OpRegion handler, which must be
available before other drivers using it are loaded, which can only be
ensured if the MFD, OpRegion and i2c-bus drivers are built-in.

Since the AXP20x MFD code is used on non x86 too we cannot simply change
this into a bool, I've tried some Kconfig magic with if x86 but I could
not get this working correctly, so this commit just documents that this
should be built-in on x86, which fixes errors like these during boot:

de85d79f4a mfd: Add Cherry Trail Whiskey Cove PMIC driver
Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non
upstreamed CHT Whiskey Cove PMIC patches.

This is a somewhat minimal version which adds irqchip support and cells
for: ACPI PMIC opregion support, the i2c-controller driving the external
charger irc and the pwrsrc/extcon block.

Further cells can be added in the future if/when drivers are upstreamed
for them.

[The above patch caused a build error on some archetectures]

From: Arnd Bergmann <arnd@arndb.de>

I ran into a build error on ARM with a platform that has a non-standard
clk implementation:

drivers/clk/clk.o: In function `clk_disable':
clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here

The problem is a device driver that uses 'select COMMON_CLK', which is
generally a bad idea: selecting a subsystem should only be done from
a platform, otherwise we run into circular dependencies. The same driver
also selects 'GPIOLIB' and 'I2C', which has a similar effect.

This turns all three into 'depends on', as it should be.

Finally, we can limit the build to x86, unless we are compile testing.

The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be
available before other drivers using it are loaded, which is why
INTEL_SOC_PMIC is a bool.

Just having the driver is not enough, the driver for the i2c-bus must
also be built in, to ensure this, this patch adds a select for it.

This fixes errors like these during boot:

While at it this patch also changes the human readable name of the Kconfig
option to make clear the INTEL_SOC_PMIC option selects support for the
Intel Crystal Cove PMIC and documents why this is a bool.

b5238b4185 mfd: intel_soc_pmic: Fix a mess with compilation units
Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.

Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.

Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.

(*) It looks like the configuration was never tested with
    INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

656211b1df mfd: Add support for DA9061
MFD support for DA9061 is provided as part of the DA9062 device driver.

The registers header file adds two new chip variant IDs defined in DA9061
and DA9062 hardware. The core header file adds new software enumerations
for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
for distinguishing between DA9061/62 devices in software.

The core source code adds a new .compatible of_device_id entry. This is
extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
.data entry now holds a reference to the enumerated device type.

A new regmap_irq_chip model is added for DA9061 and this supports the new
list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
new sub system components for DA9061. Support is added for a new DA9061
regmap_config which lists the correct readable, writable and volatile
ranges for this chip.

The probe function uses the device tree compatible string to switch on the
da9062_compatible_types and configure the correct mfd cells, irq chip and
regmap config.

Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

TI LMU (Lighting Management Unit) driver supports lighting devices below.

  LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697.

LMU devices have common features.
  - I2C interface for accessing device registers
  - Hardware enable pin control
  - Backlight brightness control
  - Notifier for hardware fault monitoring
  - Regulators for LCD display bias

It contains fault monitor, backlight, LED and regulator driver.

LMU fault monitor
-----------------
  LM3633 and LM3697 provide hardware monitoring feature.
  It enables open or short circuit detection.
  After monitoring is done, each device should be re-initialized.
  Notifier is used for this case.
  Separate patch for 'ti-lmu-fault-monitor' will be sent later.

Backlight
---------
  It's handled by TI LMU backlight consolidated driver and
  chip dependent data. Separate patchset will be sent later.

LED indicator
-------------
  LM3633 has 6 indicator LEDs. Programmable dimming pattern is also
  supported. Separate patch for 'leds-lm3633' will be sent later.

Regulator
---------
  LM3631 has 5 regulators for the display bias.
  LM3632 supports 3 regulators. One consolidated driver enables it.
  The lm363x regulator driver is already upstreamed.
