b4ead61e57 mfd: Add support for remapping twl4030-power power states
The <RESOURCE>_REMAP register allows configuration of the <RESOURCE> in case
of a sleep or off transition.

Allow this property of resources to be configured (through twl4030_resconfig)
and add code to parse these values to program the registers accordingly.

98c2e49030 mfd: Fix pcf50633-regulator drvdata usage
Currently the pcf50633-regulator driver data is set to the pcf50633 core
structure, but the pcf50633-regulator remove handler assumes that it is set to
the regulator device. This patch fixes the issue by accessing the pcf506533
core structure through its parent device and setting the driver data to the
regulator device.

bbb2e496f7 mfd: Use platform_device_add_data to set pcf50633 regulator platform data
Platform devices allocated with platform_device_alloc should use
platform_device_add_data to set the platform data, because kfree will be called
on the platform_data when the device is released.

68d641efd8 mfd: Fix memleak in pcf50633_client_dev_register
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.

0c7229f93a mfd: Convert WM835x IRQ handling to use a data table
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.

While we're at it make sure that we clean up the IRQ if we fail after

raw_init can't be removed, because ftrace events and kprobe events
use different raw_init callbacks. Though it's possible to totally
remove raw_init, I choose to leave it as it is for now.

0d782dc430 ARM: VFP: fix vfp thread init bug and document vfp notifier entry conditions
When the VFP notifier is called for flush_thread(), we may be
preemptible, meaning we might migrate to another CPU, which means
referencing the current CPU number without some form of locking is
invalid, and can cause data corruption.

For the most cases, this isn't a problem since atomic notifiers are run
under rcu lock, which for most configurations results in preemption
being disabled - except when the preemptable tree-based rcu
implementation is selected.

Let's make it safe anyway.

c2de1c3829 [ARM] pxa/zeus: make Viper pcmcia support more generic to support Zeus
The Arcom Zeus CF slot requires the same kind of support as the Viper.
To avoid code duplication, introduce a platform device that abstracts
the differences.

This also allows for the removal of the ugly export of viper_cf_rst().

965346e3b9 spi: fix probe/remove section markings
Probe/remove functions need to be marked as __devinit and __devexit
(not __init an __exit) to prevent trying to run code that has been
discarded.  This patch fixes the spi_imx driver to mark probe and
remove correctly.

35c9049b27 Add OMAP spi100k driver
This change adds the OMAP SPI 100k driver created by
Fabrice Crohas <fcrohas@gmail.com>.  This SPI bus is found on
OMAP7xx-series smartphones, and for many, the touchscreen is
attached to this bus.

The lion's share of the work was done by Fabrice on this driver --
I am merely porting it from the Linwizard project on his behalf.
