Input: add support for TI Touchscreen controller
This patch adds support for TI's touchscreen controller for a 4/5/8 wire resistive panel that is directly fed to the ADC. This touchscreen controller will be part of AM335x TI SoC. The TRM can be found at: http://www.ti.com/lit/ug/spruh73a/spruh73a.pdf Signed-off-by: Patil, Rachna <rachna@ti.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
