Subject: [PATCH] hwdb: Apply existing accel orientation quirk to all
|
|
|
8d419f |
Chromebooks
|
|
|
8d419f |
|
|
|
8d419f |
The cros-ec-accel and cros-ec-accel-legacy kernel modules internally
|
|
|
8d419f |
correct for the board-specific accelerometer mounting orientations.
|
|
|
8d419f |
Their sensor outputs are in a standard reference frame consistent across
|
|
|
8d419f |
different boards, so the orientation matrix already added for a number
|
|
|
8d419f |
of devices should apply to every device using cros-ec accelerometers.
|
|
|
8d419f |
The different matrix for the 'Nocturne' board seems to be an error.
|
|
|
8d419f |
|
|
|
8d419f |
Replace the existing hwdb rules for select Chromebooks with generic
|
|
|
8d419f |
rules that apply to all Chromebooks.
|
|
|
8d419f |
|
|
|
8d419f |
(cherry picked from commit 1800f7098a3e91a1d28697ef11a15e4b4193d21f)
