It works through the I2C bus and acts as a GPIO extender.

address
* Each sub-device provides 8 output and 8 input pins
* The chip attaches to one GPIO to signal when any of the
input GPIOs change -- at which point all chips must be
scanned for changes
This driver implements the GPIOs throught the kernel's

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.

There are also minor changes to the header file, mostly related

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 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 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.

implemented in CPLD chips on several HTC devices.
The original driver was written by Kevin O'Connor, I have adapted it to
use gpiolib and made the bus/register widths configurable.

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.

This driver provides the core functionality of the SM501, which is a
multi-function chip including two framebuffers, video acceleration, USB,
and many other peripheral blocks.
The driver exports a number of entries for the peripheral drivers to use.

This fixes u32 vs. pm_message_t confusion and uses cleaner
