Subject: [PATCH] pxa: add partial keypad support for mainstone
This is partial because mainstone's keypad is really special, some of
the keys like '1', '2', ... are actually connected to two row/column
juntions, thus pressing '1' is equivalent to pressing 'A' & 'H'.
This is really brain damanged since it makes distinguishing between
pressing '1' and multiple keys pressing of 'A' & 'H' difficult.
So these special keys are not supported for the time being.
