Android expects BTN_TOUCH events when pen state changes. Add BTN_TOUCH
event reporting to allow use of wm97xx touchscreen controller with
Android devices.

I'd still like to see more consistency over touchscreen drivers on this
one, BTW - if we're doing this it should be done for all touchscreen
drivers (either by updating the individual drivers or having the input
core do it). This isn't the only touchscreen driver that doesn't do
BTN_TOUCH.

Most touchscreen drivers already have BTN_TOUCH event generation:

If there no objection I can make a similar patch for mainstone-wm97xx.c and ucb1400_ts.c

No problem for me. Please see the other two accelerated WM97xx drivers
I posted today too.

Add BTN_TOUCH event reporting to ucb1400_ts and accelerated mainstone-wm97xx
touchscreen drivers. Together with previously posted similar patch for
wm97xx-core this will make all touchscreen drivers behave consistently wrt.
BTN_TOUCH.

The below patch adds BTN_TOUCH event reporting for two accelerated drivers
you've posted yesterday [1] and [2]. This patch is incremental vs. the first spin.
