Linus Walleij d619bc143e regulator: AB3100 support
This adds support for the regulators found in the AB3100
Mixed-Signal IC.

It further also defines platform data for the ST-Ericsson
U300 platform and extends the AB3100 MFD driver so that
platform/board data with regulation constraints and an init
function can be passed down all the way from the board to
the regulators.

Amit Kucheria 75a7456539 mfd: Print warning for twl4030 out-of-order script loading
When the sleep script is loaded before the wakeup script, there is a
chance that the system might go to sleep before the wakeup script
loading is completed. This will lead to a system that does not wakeup
and has been observed to cause non-booting boards.

Various options were considered to solve this problem, including
modification of the core twl4030 power code to be smart enough to
reorder the loading of the scripts. But it felt too over-engineered.

Hence this patch just warns the DPS script developer so that they may be
reordered in the board-code itself.

Amit Kucheria ebf0bd366e mfd: Add support for TWL4030/5030 dynamic power switching
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.

Mark Brown 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.

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.

Bit 1 and 3 should be checked for write protection. However
on the EVM bits 2 and 4 gives this status.

Paul Fertser bd8ef10261 mfd: revise locking for pcf50633 ADC
Current implementation is prone to races, this patch attempts to remove all
but one (in pcf50633_adc_sync_read).

The idea is that we need to guard the queue access only on inserting and
removing items. If we insert and there're no more items in the queue it
means that the last irq already happened and we need to trigger ADC
manually. If not, then the next conversion will be triggered by the irq
handler upon completion of the previous.

Paul Fertser 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.

Russell King 1cef8e4107 mfd: twl4030 irq fixes
The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is
calling the 'unmask' function in a process context. :The mask/unmask/ack
functions are only designed to be called from the IRQ handler code,
or the proper API interfaces found in linux/interrupt.h.

Also there is no need to have IRQ chaining mechanism. The right way to
handle this is to claim the parent interrupt as a standard interrupt
and arrange for handle_twl4030_pih to take care of the rest of the devices.

Thomas Gleixner 516eca2726 drivers/mfd: remove obsolete irq_desc_t typedef
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users and remove the typedef.
