Extend the tca6416 driver to use enable_irq_wake() and disable_irq_wake()
in the suspend/resume hooks.

This makes it possible to wake up from suspend-to-ram using a tca6416 key
on the sh7372 mackerel board.

There are two types of 1FGT devices supported in wacom_wac.c.
Changing them to follow the existing touchscreen format, i.e.,
only report BTN_TOUCH as a valid tool type.

Touch data will be ignored if pen is in proximity. This requires
a touch up event sent if touch was down when pen comes in. The
touch up event should be sent before any pen events are emitted.
Otherwise, two pointers would race for the cursor.

However, we can not send a touch up inside wacom_tpc_pen since
pen and touch are on different logical port. That is why we
have to check if touch is up before sending pen events.

The mxt_check_matrix_size() is currently setting the CTE mode to match
xline/yline information that is in the platform data, but it does not
take into account for example the fact that we could have a key array
in use too (key array would use some x/y lines as well).

It would be better to simply rely on the configuration data, and make
sure that the CTE mode set in there matches the touch object (touchscreen,
key array, proximity) configuration (which are set in the config data too).

The MCS50XX series has a HW bug that requires explicit chip power down.

pins (powerup, interrupt) are pulled up and residue current continues

Enable Runtime PM functionality in OMAP4 driver based on the following
assumptions:

- keyboard controller in wakeup domain so it is always on and power
  impact is minimal;
- in OMAP4 the device control is at module/device level and ick/fclk
  level control is difficult so cutting of clocks will prevent
  interrupts.

Instead of open-coding copying of data structures from userspace use
memdup_user() and strndup_user(). Note that this introduces change in
