Add resource managed API devm_mfd_add_devices() for the mfd_add_devices().

This helps in reducing code in error path as it is not required
to call mfd_remove_devices() explicitly to remove all child-devices.
In some cases, it also helps not to implement .remove() callback
which get called during driver unbind.

The X-Powers AXP809 is a new PMIC that is paired with Allwinner's A80
SoC, along with a slave AXP806 PMIC.

This PMIC is quite similar to the earlier AXP223, though the interrupts
and regulator have changed a bit.

This patch adds support for the interrupts and power button of the PMIC.

1a46712aa9 This is the bulk of GPIO changes for kernel v4.6:
Core changes:
 
 - The gpio_chip is now a *real device*. Until now the gpio chips
   were just piggybacking the parent device or (gasp) floating in
   space outside of the device model. We now finally make GPIO chips
   devices. The gpio_chip will create a gpio_device which contains
   a struct device, and this gpio_device struct is kept private.
   Anything that needs to be kept private from the rest of the kernel
   will gradually be moved over to the gpio_device.
 
 - As a result of making the gpio_device a real device, we have added
   resource management, so devm_gpiochip_add_data() will cut down on
   overhead and reduce code lines. A huge slew of patches convert
   almost all drivers in the subsystem to use this.
 
 - Building on making the GPIO a real device, we add the first step
   of a new userspace ABI: the GPIO character device. We take small
   steps here, so we first add a pure *information* ABI and the tool
   "lsgpio" that will list all GPIO devices on the system and all
   lines on these devices. We can now discover GPIOs properly from
   userspace. We still have not come up with a way to actually *use*
   GPIOs from userspace.
 
 - To encourage people to use the character device for the future,
   we have it always-enabled when using GPIO. The old sysfs ABI is
   still opt-in (and can be used in parallel), but is marked as
   deprecated. We will keep it around for the foreseeable future,
   but it will not be extended to cover ever more use cases.
 
 Cleanup:
 
 - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
   includes. This dates back to when GPIO was an opt-in feature and
   no shared library even existed: just a header file with proper
   prototypes was provided and all semantics were up to the arch to
   implement. These patches make the GPIO chip even more a proper
   device and cleans out leftovers of the old in-kernel API here
   and there. Still some cruft is left but it's very little now.
 
 - There is still some clamping of return values for .get() going
   on, but we now return sane values in the vast majority of drivers
   and the errorpath is sanitized. Some patches for powerpc, blackfin
   and unicore still drop in.
 
 - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
   implementations to use gpiochip_add_data() and cut down on code
   lines.
 
 - MPC8xxx is converted to use the generic GPIO helpers.
 
 - ATH79 is converted to use the generic GPIO helpers.
 
 New drivers:
 
 - WinSystems WS16C48
 
 - Acces 104-DIO-48E
 
 - F81866 (a F7188x variant)
 
 - Qoric (a MPC8xxx variant)
 
 - TS-4800
 
 - SPI serializers (pisosr): simple 74xx shift registers connected
   to SPI to obtain a dirt-cheap output-only GPIO expander.
 
 - Texas Instruments TPIC2810
 
 - Texas Instruments TPS65218
 
 - Texas Instruments TPS65912
 
 - X-Gene (ARM64) standby GPIO controller

     have it always-enabled when using GPIO.  The old sysfs ABI is still
     opt-in (and can be used in parallel), but is marked as deprecated.

     We will keep it around for the foreseeable future, but it will not
     be extended to cover ever more use cases.

  Cleanup:

   - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
     includes.

     This dates back to when GPIO was an opt-in feature and no shared
     library even existed: just a header file with proper prototypes was
     provided and all semantics were up to the arch to implement.  These
     patches make the GPIO chip even more a proper device and cleans out
     leftovers of the old in-kernel API here and there.

     Still some cruft is left but it's very little now.

   - There is still some clamping of return values for .get() going on,
     but we now return sane values in the vast majority of drivers and
     the errorpath is sanitized.  Some patches for powerpc, blackfin and
     unicore still drop in.

   - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
     implementations to use gpiochip_add_data() and cut down on code
     lines.

   - MPC8xxx is converted to use the generic GPIO helpers.

   - ATH79 is converted to use the generic GPIO helpers.

  New drivers:

   - WinSystems WS16C48

   - Acces 104-DIO-48E

   - F81866 (a F7188x variant)

   - Qoric (a MPC8xxx variant)

   - TS-4800

   - SPI serializers (pisosr): simple 74xx shift registers connected to
     SPI to obtain a dirt-cheap output-only GPIO expander.

0343b2f4e4 mfd: intel-lpss: Pass I2C configuration via properties on BXT
I2C host controller need to be configured properly in order to meet I2C
timings specified in the I2C protocol specification. Some Intel Broxton
based machines do not have this information in the ACPI namespace (or the
boot firmware does not support ACPI at all) so we use build-in device
properties instead.

dcdf11739d mfd: ipaq-micro: Use __maybe_unused to hide pm functions
The ipaq-micro driver uses SET_SYSTEM_SLEEP_PM_OPS() to
remove the reference to its resume function, but does
not use an #ifdef around the definition, so we get
a build warning:

drivers/mfd/ipaq-micro.c:379:12: error: 'micro_resume' defined but not used [-Werror=unused-function]

This adds a __maybe_unused annotation so the compiler knows
it can silently drop it instead of warning.

The max77686 MFD driver supports both the Maxim 77686 and Maxim 77802
PMICs but only the OF device table contains entries for both devices.

The max77802 entry is missing in the I2C device ID table which isn't
a problem currently since the driver only supports DT but it will be
needed if the driver is changed to be built as a module since the I2C
core always reports a I2C modalias uevent so auto-load will not work.

7f8ada1a84 mfd: max77686: Export OF module alias information
When the device is registered via OF, the OF table is used to match the
driver instead of the I2C device ID table but the entries in the latter
are used as aliasses to load the module if the driver was not built-in.

This is because the I2C core always reports an I2C module alias instead
of an OF one but that could change so it is better to always export it.

name with an entry on the .id_table if provided and fallbacks to match with
the driver's name if a table is not provided.

Using a platform device ID to match is more explicit, allows the driver to
support more than one device and also the MODULE_DEVICE_TABLE macro can be

0e5df61d26 mfd: da9063: Fix missing volatile registers in the core regmap_range volatile lists
Add an updated set of registers listed in the core regmap_range volatile
ranges defined for the DA9063.

These new registers contain bits that cannot be considered under the full
control of software. Under various conditions the hardware will set and/or
automatically clear bit(s) contained in these registers.

When using a cached version of regmap, the volatility of these registers must
be identified otherwise the regmap operations may not ensure the registers
are explicitly altered.

As well as updating the list of volatile registers, this change will fix a
corner case discovered in the DA9063 ONKEY which is used by the DA9063 core.

In the ONKEY case, the CONTROL_B register is now listed as volatile in the
regmap_range because it contains the bit field NONKEY_LOCK. This bit can be
altered by hardware, in which case regmap must be notified of its ability
to be manpiulated outside of software control.
