From 227c011b2e046dd4d36d9e00e3d9c88097b2a4c3 Mon Sep 17 00:00:00 2001 From: Roderick Colenbrander Date: Tue, 7 Mar 2017 15:45:00 -0800 Subject: HID: sony: Report DS4 motion sensors through a separate device The DS4 motion sensors are currently mapped by the hid-core driver to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because the device already exhausted ABS_X-ABS_RZ. For a part the mapping by hid-core is accomplished by a fixup in hid-sony as the motion axes actually use vendor specific usage pages. This patch makes the DS4 use a separate input device for the motion sensors and reports acceleration data through ABS_X-ABS_Z and gyroscope data through ABS_RX-ABS_RZ. In addition it extends the event spec to allow gyroscope data through ABS_RX-ABS_RZ when INPUT_PROP_ACCELEROMETER is set. This change was suggested by Peter Hutterer during a discussion on linux-input.
