ARM: mach-shmobile: ap4evb: modify tsc2007 platform settings
This patch modify x_plate_ohms to correct value for tsc2007, and removed un-necessary ts_get_pendown_state(). gpio_pull_up() was removed also. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
