From: Ping Cheng Date: Tue, 27 Jan 2015 21:30:03 +0000 (-0800) Subject: HID: wacom: add support for Cintiq 27QHD and 27QHD touch X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=500d4160abe9a2e88b12e319c13ae3ebd1e18108;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git HID: wacom: add support for Cintiq 27QHD and 27QHD touch These devices have accelerometers. To report accelerometer coordinates, a new property, INPUT_PROP_ACCELEROMETER, is added.
