Subject: [PATCH v1 12/12] arm64: dts: librem5-devkit: add lsm9ds1 mount matrix
Date: Wed,  5 Feb 2020 15:30:03 +0100	[thread overview]
Message-ID: <20200205143003.28408-13-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20200205143003.28408-1-martin.kepplinger@puri.sm>

The IMU chip on the librem5-devkit is not mounted at the "natural" place
that would match normal phone orientation (see the documentation for the
details about what that is).

Since the lsm9ds1 driver supports providing a mount matrix, we can describe
the orientation on the board in the dts:

Create a right-handed coordinate system (x * -1; see the datasheet for the
axis) and rotate 180 degrees around the y axis because the device sits on
the back side from the display.

this is what I've previously sent as a single patch already:
