…cally labeled buttons on touch screen surfaces Adds a driver for supporting permanet, physically labeled, buttons on touchscreen surfaces. As are common on android phones designed with android 1.0 to 2.3 in mind. The driver works by attaching to another input device and mirroring its events, while inserting key events and filtering for touches that land on the buttons. Buttons are arbitrary rectangles configurable via dts. Signed-off-by: Carl Philipp Klemm <carl@uvos.xyz>
