This is done as simple code transformation, the semantics of the
IRQ API provided by the core are are still very different to those
of genirq (mainly with regard to masking).

This is currently unused by the wm8350 drivers but getting it merged
now will reduce merge issues in the future when implementing wm8350
genirq support.

Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.

Rather than open coding individual IRQs in each function which
manipulates them store data for IRQs in a table which is then
referenced in the users.
This is a substantial code shrink and should be a performance win in
cases where only a single IRQ goes off at once since instead of
reading four of the second level IRQ registers for each interrupt
we read only the sub-registers which have had an interrupt flagged.

In preparation for refactoring - it's over 700 lines of well-isolated
code and having it in a file by itself makes things more managable.
While we're at it make sure that we clean up the IRQ if we fail after
acquiring it on init.

The WM8320 is an integrated power management subsystem providing
voltage regulators, RTC, watchdog and other functionality. The
WM8320 is derived from the WM831x and therefore shares most of
the driver code with the WM831x.

This adds core driver support for AB4500 mixed signal
multimedia & power management chip. This connects to U8500
on the SSP (pl022) and exports read/write functions for
the device to get access to this chip. This also registers
the client devices and sets the parent.

This adds a core driver for 88PM8607 found in Marvell DKB development
platform. This driver is a proxy for all accesses to 88PM8607
sub-drivers which will be merged on top of this one, RTC, regulators,
battery and so on.
This chip is manufactured by Marvell.

This patch adds platform data with a function for power

code can provide their own functions so power can be enabled
and disabled for the sd-cards.

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).
