Balaji T K e8deb28ca8 mfd: Add support for twl6030 irq framework
This patch adds support for phoenix interrupt framework. New iInterrupt
status register A, B, C are introduced in Phoenix and are cleared on write.
Due to the differences in interrupt handling with respect to TWL4030,
twl6030-irq.c is created for TWL6030 PMIC

Mark Brown 0125350382 mfd: Force I2C to be built in when building WM831x
This works around issues with allmodconfig where it won't propagate the
dependency from the WM831x core back to the I2C and MFD cores.  When
doing allmodconfig this causes WM831x to be omitted and ensures that in
normal builds the dependencies get shaken out.

Peter Ujfalusi 0b83ddebc6 MFD: twl4030: add twl4030_codec MFD as a new child to the core
New MFD child to twl4030 MFD device.

Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.

This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.

The platform specific configuration data is passed along to the
child drivers (audio, vibra).

queueing/abstraction.

This chip is used on a lot of Motorola phones, it was manufactured by TI

David Brownell 0931a4c6db mfd: dm355evm msp430 driver
Basic MFD framework for the MSP430 microcontroller firmware used
on the dm355evm board:

 - Provides an interface for other drivers: register read/write
   utilities, and register declarations.

 - Directly exports:
     * Many signals through the GPIO framework
         + LEDs
         + SW6 through gpio sysfs
	 + NTSC/nPAL jumper through gpio sysfs
	 + ... more could be added later, e.g. MMC signals
     * Child devices:
	+ LEDs, via leds-gpio child (and default triggers)
	+ RTC, via rtc-dm355evm child device
	+ Buttons and IR control, via dm355evm_keys

 - Supports power-off system call.  Use the reset button to power
   the board back up; the power supply LED will be on, but the
   MSP430 waits to re-activate the regulators.

 - On probe() this:
     * Announces firmware revision
     * Turns off the banked LEDs
     * Exports the resources noted above
     * Hooks the power-off support
     * Muxes tvp5146 -or- imager for video input

Unless the new tvp514x driver (tracked for mainline) is configured,
this assumes that some custom imager driver handles video-in.

This completely ignores the registers reporting the output voltages
on the various power supplies.  Someone could add a hwmon interface
if that seems useful.

David Brownell a603a7fa87 mfd: TWL4030 core driver
This patch adds the core of the TWL4030 driver, which supports
chips including the TPS65950.  These chips are multi-function; see

  http://focus.ti.com/docs/prod/folders/print/tps65950.html

Public specs are in the works.  For now, the block diagram on
the second page of the datasheet is fairly informative.

There are some known issues with this core code.  Most notably,
the IRQ dispatching needs simplification (to use more of genirq),
generalization (integrating support for secondary IRQ dispatch
as well as primary, and removing the build dependency on OMAP),
and then probably updating to leverage threaded IRQ support
(expected to arrive in mainline "soon").

Once the core is in mainline, drivers for other parts of this
chip can follow its lead and start swimming upstream too.

Marek Vašut d9105c2b01 [ARM] 5184/1: Split ucb1400_ts into core and touchscreen
This patch splits ucb1400_ts into ucb1400_ts and ucb1400_core.
Since this chip supports more features than only touchscreen,
it was necessary to prepare it for feature addition. The
previous functionality is preserved by applying this patch.

Samuel Ortiz 1c2c30acc5 mfd: have TMIO drivers and subdevices depend on ARM
The TMIO chips are only found (and thus tested) on ARM machines.
Moreover, we don't want the TMIO cells to be built if one of the TMIO
driver is not selected (which indirectly make the TMIO cells drivers
depend on ARM as well).

Ian Molton cbdfb42639 mfd: driver for the TC6387XB TMIO controller.
This patch adds support for the TC6387XB. Unlike other TMIO devices this one
has only one subdevice and no interrupt mux, however using the MFD framework
allows it to share the TMIO MMC driver.

Michael Buesch 7444a72eff gpiolib: allow user-selection
This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.
