Currently during boot, and every suspend/resume, we call
regulator_set_optimum_mode on every touchsdcreen regulator. However,
some regulators don't support this function, and this will cause
set_optimum_mode to print an error when this occures. Correct this by
checking if it is valid to call set_optimum_mode on a given regulator
before doing so.

The atmel_mxt_ts driver manipulates the touch coordinates
if they are < 1024. In cases when the display < 1024 and
virtual key area > 1024, there is a problem in reporting
the coordinates for the virtual key area. Add new pdata
variables which can handle this.

The sysfs attribute show method (mxt_object_show) is limited to show
object information up to (PAGE_SIZE - 1) bytes. We need a way to get
the complete information of all objects. The object information can
be obtained from <debugfs-mount>/atmel_mxt_ts/object.

Add support for dynamic configuration data update if the target can
support more than one Atmel chip. Platform data contains an array of
supported config data along with family ID, variant ID and firmware
version. Driver searches for matching family ID, variant ID and
firmware version, and uses the corresponding config data to program.

Atmel mxt1386 touch controller has the touch pressure information but
the current driver atmel_mxt_ts does not expose it to the user space.
This patch makes the driver report the touch pressure information to
user space.

Delay in headset removal causes adverse effects in
userspace such as delay (loss) in audio/video routing.
Delay was introduced to reject spurious switch events. These
events are already rejected based on the headset status.

The previous algorithm requires that kpd_trigger_delay_us be set to
1/32 of the preferred trigger delay. The new algorithm allows setting
kpd_trigger_delay_us to the preferred trigger delay directly.
The actual delay can only be one of the eight levels: 2 sec, 1 sec,
1/2 sec, 1/4 sec, 1/8 sec, 1/16 sec, 1/32 sec, and 1/64 sec. The valid
range of kpd_trigger_delay_us is 1/64 second to 2 seconds. A value
within the valid range will be rounded down to the closest level. Any
value outside the valid range will be rejected.
Update board files for targets that use this driver accordingly.

Move the following subdevices to use the pm8xxx interface -
mpp, irq, gpio, keypad, power-key, leds, othc, vibrator,
rtc, batt-alarm, thermal, upl, nfc, pwm, xoadc, regulators,
xo-buffers, charger.
This allows usage of a common driver for modules which are same
across multiple PM8XXX PMICs. It also provides flexibility
to add/remove subdevices for multiple board configurations.
