Andres Salomon fcd67979d3 w1: Use mfd_data instead of driver_data for dsw1wm.c
Use mfd_data for passing information from mfd drivers to mfd

Clients that were using driver_data now access .mfd_data

The led_cell.driver_data line is dropped from htc-pasic3.c in this
patch as well.  It's not used in mainline (there's no leds-pasic3
platform driver), so it should be safe to take care of that here.

Andres Salomon 65e523595a mfd: Rename platform_data field of mfd_cell to mfd_data
Rename the platform_data variable to imply a distinction between
common platform_data driver usage (typically accessed via
pdev->dev.platform_data) and the way MFD passes data down to
clients (using a wrapper named mfd_get_data).

All clients have already been changed to use the wrapper function,
so this can be a quick single-commit change that only touches things
in drivers/mfd.

Andres Salomon 4ec1b54c4d mfd: mfd_cell is now implicitly available to mc13xxx drivers
The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.

Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack.  In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.

No clients (in mainline kernel, I'm told that drivers exist in external

Andres Salomon fe891a008f mfd-core: Unconditionally add mfd_cell to every platform_device
Previously, one would set the mfd_cell's platform_data/data_size to point
to the current mfd_cell in order to pass that information along to drivers.

This causes the current mfd_cell to always be available to drivers.  It
also adds a wrapper function for fetching the mfd cell from a platform
device, similar to what originally existed for mfd devices.

Drivers who previously used platform_data for other purposes can still
use it; the difference is that mfd_get_data() must be used to
access it (and the pdata structure is no longer allocated in
mfd_add_devices).

Note that mfd_get_data is intentionally vague (in name) about where
the data is stored; variable name changes can come later without having
to touch brazillions of drivers.

Cyril Chemparathy 03df0f6294 mfd: add driver for sequencer serial port
TI's sequencer serial port (TI-SSP) is a jack-of-all-trades type of serial port
device.  It has a built-in programmable execution engine that can be programmed
to operate as almost any serial bus (I2C, SPI, EasyScale, and others).

This patch adds a driver for this controller device.  The driver does not
expose a user-land interface.  Protocol drivers built on top of this layer are
expected to remain in-kernel.

Mark Brown 77bd70e900 mfd: Don't suspend WM8994 if the CODEC is not suspended
ASoC supports keeping the audio subsysetm active over suspend in order
to support use cases such as audio passthrough from a cellular modem
with the main CPU suspended. Ensure that we don't power down the CODEC
when this is happening by checking to see if VMID is up and skipping
suspend and resume when it is. If the CODEC has suspended then it'll
turn VMID off before the core suspend() gets called.
