From 510c8b7c168bcad75e2864f73e5125d7218ee3cf Mon Sep 17 00:00:00 2001 From: Roderick Colenbrander Date: Tue, 7 Mar 2017 15:45:10 -0800 Subject: [PATCH] HID: sony: Expose DS3 motion sensors through separate device This patch adds a separate evdev node for the DS3 its motion sensors. We only expose the accelerometers as the gyroscope is extremely difficult to manage and behavior varies a lot between hardware revisions.
