Subject: [PATCH] Input: wm97xx: add BTN_TOUCH event to wm97xx to use it with Android
Date: Tue, 17 Feb 2009 11:43:33 +0200 [thread overview]
Message-ID: <1234863813-12211-1-git-send-email-mike@compulab.co.il> (raw)
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.
