linux-toradex.git/drivers/input/touchscreen/surface3_spi.c, branch v4.11-rc6 Linux kernel for Apalis and Colibri modules Input: surface3_spi - add surface pen support for Surface 3 2016-05-27T23:33:34+00:00 Stephen Just stephenjust@gmail.com 2016-05-27T23:29:39+00:00 72fb4765ac9eea56a94282f29cdc70706f21494e This change creates a second input device which will handle input from a Surface Pen. The Surface Pen supplies a different packet header than touch events, so it is simple to handle one or the other. This patch handles both the newer Surface Pen with one button, and the older variant with a second button to switch to Eraser mode.

Input: add new driver for the Surface 3 2016-05-19T16:35:19+00:00 Benjamin Tissoires benjamin.tissoires@redhat.com 2016-05-19T16:24:06+00:00 4feacbc24eea0c5f36728017575cc0ad28d8758b This is a basic driver for the Surface 3. I am not so sure it will work with any firmwares as most values are encoded, but given that I only have access to my current device with its firmware and I don't have the datasheet, it should be OK for now. The Surface Pen is not supported (if it is supposed to be). I'll work on this when I get one.
