This patch adds an MFD driver for the SuperH Mobile SDHI
hardware block. At this point the driver simply wraps the
tmio-mmc driver with some clock code. In the future this
driver is the place to put SDHI specific hotplug code.

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).

The TWL4030/5030 family of multifunction devices allows board-specific
control of the the various regulators, clock and reset lines through
'scripts' that are loaded into its memory. This allows for Dynamic Power
Switching (DPS).
Implement board-independent core support for DPS that is then used by
board-specific code to load custom DPS scripts.

This adds the ability to read out OTP (One-Time Programmable)
registers in the AB3100 MFD ASIC. It's a simple sysfs file you
can cat to prompt. The OTP registers of the AB3100 are used to
store various device-unique information such as customer ID,
product flags and the 3GPP standard IMEI (International Mobile
Equipment Indentity) number.

The PCAP Asic as present on EZX phones is a multi function device with
voltage regulators, ADC, touch screen controller, RTC, USB transceiver,
leds controller, and audio codec.
It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.
This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).

This adds a core driver for the AB3100 mixed-signal circuit
found in the ST-Ericsson U300 series platforms. This driver
is a singleton proxy for all accesses to the AB3100
sub-drivers which will be merged on top of this one, RTC,
regulators, battery and system power control, vibrator,
LEDs, and an ALSA codec.

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.

- Move it into a separate file; clean and streamline it
- Restructure the init code for reuse during secondary dispatch
- Support both levels (primary, secondary) of IRQ dispatch
- Use a workqueue for irq mask/unmask and trigger configuration
Code for two subchips currently share that secondary handler code.
One is the power subchip; its IRQs are now handled by this core,
courtesy of this patch. The other is the GPIO module, which will
be supported through a later patch.
There are also minor changes to the header file, mostly related
to GPIO support; nothing yet in mainline cares about those. A
few references to OMAP-specific symbols are disabled; when they
can all be removed, the TWL4030 support ceases being OMAP-specific.

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.

The WM8350 provides a number of user-configurable pins providing access
to various signals generated by the functions on the chip. These are
referred to as GPIO pins in the device documentation but in Linux terms
they are more general than that, providing configuration of alternate
functions.
This patch implements support for selecting the alternate functions for
these pins. They can also be used as GPIOs in the normal Linux sense -
a subsequent patch will add support for doing so.
This code was all written by Liam Girdwood and has had minor updates
and rearrangements by Mark Brown.

The WM8350 is an integrated audio and power management subsystem
intended for use as the primary PMIC in mobile multimedia applications.
The WM8350 can be controlled via either I2C or SPI - the control
interface is provided by a separate module in order to allow greatest
flexibility in configuring the kernel.
This driver was originally written by Liam Girdwood and has since been
updated to current kernel APIs and split up for submission by me. All
the heavy lifting here was done by Liam.

The WM8400 is a highly integrated audio CODEC and power management unit
optimised for use in mobile multimedia applications. This patch adds
core support for the WM8400 to the MFD subsystem.
Both I2C and SPI access are supported by the hardware but currently only
I2C access is implemented. The code is structured to allow SPI support
to be slotted in later.

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.

This is a patch for the Compaq ASIC3 multi function chip, found in many
PDAs (iPAQs, HTCs...).
It is a simplified version of Paul Sokolovsky's first proposal [1]. With
this code, it is basically a GPIO and IRQ expander. My plan is to add more
features once this patch gets reviewed and accepted.
