Subject[PATCH 1/5] Input: wm97xx: add BTN_TOUCH event to wm97xx to use it with Android
Date
From: Mike Rapoport <mike@compulab.co.il>

Please CC me, I'm not subscribed to linux-input

Android expects BTN_TOUCH events when pen state changes. Add BTN_TOUCH
event reporting to allow use of wm97xx touchscreen controller wiht
Android devices.
