Introduce pxa27x_keypad_config() for keypad registers configuration and remove the reg_kpc, reg_kprec from platform data structure so that configurations of keypad registers can be centralized to a single function. It can also be re-used when resuming. Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
