956f25a677 mfd: AB3100 accessor function cleanups
This adds the _interruptible suffix to the AB3100 accessor
functions on par with mutex_lock_interruptible() that's used
for blocking simultaneous calls to the AB3100 acessor functions.
Since these accesses are slow on a 100kHz I2C bus and may line
up waiting for the mutex, we need to handle interruption by
system shutdown or kill signals and may just as well denote that
in the function names.

d1c6b4fe66 regulator: Add WM831x LDO support
The WM831x series of devices provide three types of LDO:

 - General purpose LDOs supporting voltages from 0.9-3.3V
 - High performance analogue LDOs supporting voltages from 1-3.5V
 - Very low power consumption LDOs intended to support always on
   functionality.

This patch adds support for all three kinds of LDO. Each regulator
is probed as an individual platform device with resources used to
provide the register map location of the regulator. Mixed hardware
and software control of regulators is not current supported.

The current settings which can be used with the WM831x current sinks
can't easily be mapped between register values and currents at run
time without a lookup table since the values scale logarithmically
to match the way the human eye interprets brightness. This lookup
table is inclided in the core since several drivers need to use it.

7d4d0a3e73 mfd: Add WM831x interrupt support
The WM831x includes an interrupt controller managing interrupts for
the various functions on the chip. This patch adds support for the
core interrupt block on the device.

Ideally this would be supported by genirq, particularly for the
GPIOs, but currently genirq is unable to cope with controllers on
interrupt driven buses so we cut'n'paste the generic interface.
Once genirq is able to cope chips like this it should be a case
of filing the prefixes off the code and redoing wm831x-irq.c to
move over.

3bed6e415f mfd: Allow multiple MFD cells with the same name
Provide basic support for MFDs having multiple cells of a given
type with different IDs by adding an id to the mfd_cell structure
and then adding that to the id passed in to mfd_add_devices().

As it stands this approach requires that MFDs using this feature
deal with ensuring that there aren't any ID collisions resulting
from multiple MFDs of the same type being instantiated. This needs
to happen with the existing code too, but with this approach there
is a knock on effect on the IDs for non-duplicated devices.

ed52e62ebe mfd: use a dedicated workqueue for pcf50633 irq processing
Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.

I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

This driver requests a clock that usually is supplied by the MFD in which

For now, this patch removes the clock handling from DS1WM altogether,
trusting that the MFD enable/disable functions will switch the clock if
needed. The clock rate is obtained from a new parameter in driver_data.

6a3d119b4c mfd: PCF50633 gpio support

here.
