The timberdale FPGA is found on the Intel in-Vehicle Infotainment reference board
russelville.
The driver is a PCI driver which chunks up the I/O memory and distributes interrupts
to a number of platform devices for each IP inside the FPGA.

In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.
For twl6030 audio codec, the following data may be passed:
- audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
transition powers codec up. Setting audpwron_gpio to a negative value
means that codec will use manual power sequence instead of automatic
sequence
- naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
to low when an interrupt (codec ready, plug insertion/removal, etc) is
detected
However, codec driver can operate if any or none of them are passed.

This fixes several things while still providing the old API:
- simplify and fix locking
- better error handling
- don't ack all irqs making it impossible to detect a reset of the
rtc
- use a timeout variant to wait for completion of ADC conversion
- provide platform-data to regulator subdevice (This allows making
struct mc13783 opaque for other drivers after the regulator driver is
updated to use its platform_data.)
- expose all interrupts
- use threaded irq
After all users in mainline are converted to the new API, some things
(e.g. mc13783-private.h) can go away.

Bring the WM8350 IRQ API more in line with the generic IRQ API by
masking and unmasking interrupts as they are requested and freed.
This is mostly just a case of deleting the mask and unmask calls
from the individual drivers.
The RTC driver is changed to mask the periodic IRQ after requesting
it rather than only unmasking the alarm IRQ. If the periodic IRQ
fires in the period where it is reqested then there will be a
spurious notification but there should be no serious consequences
from this.
The CODEC drive is changed to explicitly disable headphone jack
detection prior to requesting the IRQs. This will avoid the IRQ
firing with no jack set up.

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).

This patch allows UCB1400 to get IRQ GPIO from platform data. In case
platform_data are not supplied or the IRQ supplied in the platform_data
is negative, fall back to the old IRQ detection algorithm.

The backup battery on WM831x is a separate IP block to the main PMU
and is largely unrelated to the main supply functionality. Factor it
out into a separate driver in order to reflect this and better support
future hardware versions.

This patch adds an MFD driver for the SuperH Mobile SDHI
hardware block. At this point the driver simply wraps the
tmio-mmc driver with some clock code. In the future this
driver is the place to put SDHI specific hotplug code.

Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:

plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)

other_files="drivers/leds/leds-ams-delta.c \

drivers/mtd/nand/ams-delta.c"
for header in $headers; do
old="#include <mach\/$header"
new="#include <plat\/$header"
for dir in $omap_dirs; do
find $dir -type f -name \*.[chS] | \
xargs sed -i "s/$old/$new/"

The usb regulator supplies (usb1v5, usb1v8 & usb3v1) must be available
before adding the twl4030_usb child, else twl4030_usb_ldo_init() will
always fail thus causing boot lock-up.
This patch fixes boot on OMAP systems using the twl4030 usb transceiver.

After m68k's task_thread_info() doesn't refer to current,

The I2C_CLIENT_INSMOD_1 macro is only useful for i2c drivers which
implement device detection. The ab3100 driver doesn't, so there is no
point in calling it.

This makes it consistent with other buses (platform, i2c, vio, ...). I'm
not sure why we use the prefixes, but there must be a reason.
This was easy enough to do it, and I did it.

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.
