sh: kfr2r09 board support - KEYSC keypad
This patch adds KEYSC keypad support to the kfr2r09 board. The keys driven by the sh7724 on-chip KEYSC block are described as a platform device and platform data for the sh_keysc driver. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
