* Modeled after the old gesture handling code in fw/b * This allows us to use device specific code to handle s-pen gestures instead of polluting fw/b * Supports the following gestures: - Swipe right - Swipe left - Swipe down - Swipe up - Long press * To trigger the gestures, press the button on the s-pen, execute the gesture action, and then release the side button of the s-pen * This patch also blocks touch input from the s-pen when the stylus button is pressed, to avoid causing unintended touch input Change-Id: I55651a36d147ba69e6dbd987d1a267f544570ba0 Signed-off-by: Paul Keith <javelinanddart@gmail.com>
