If the sub-probe functions fail, we need to pass up the error code to the
higher levels from the probe function. We currently always return 0 even
if there was an error so higher levels don't report problems.

The MELPAS MCS-5000 is the touchscreen controller. The overview of this
controller can see at the following website:

This driver is tested on s3c6410 NCP board and supports only the i2c
interface.

Add the cpu.c and dev.c and modify w90p910 platform
to apply to use the common API(provided by cpu.c and dev.c)
at the same time, I renamed all w90x900 to nuc900 in every
c file of w90x900 platform and touchscreen's driver name.

Sometimes, when using the touchscreen, it stops working till next restart
and the following message is printed:
ucb1400: unexpected IE_STATUS = 0x0
The following patch retriggers the touchscreen interrupt unconditionally.
This prevents hanging of the touchscreen in case of bogus interrupt
occurence.

This patch enables ADC filtering on UCB1400 codec by default. The
benefit from this change is mostly on some Colibri boards where
the ADCSYNC pin of the UCB1400 codec isn't connected causing the
touchscreen to jitter very badly. This change has no visible
effect on boards where the ADCSYNC pin is connected.

This adds a struct eeti_ts_platform_data which currently holds only one
value to specify the interrupt polarity.
The driver has a fallback if no platform data is passed in via the
i2c_board_info, so no regression is caused.

Properly shut off interrupts/delayed work by free-ing IRQ first
and then ensuring that enable/disable is balanced. Also add
__devinit/__devexit markings, restore poll delay/period scheduling
logic, make sure we call exit_platform_hw() method when probe
fails.
