Subject: [PATCH v3] arm64: dts: imx8m*-venice-gw75xx: add Accelerometer device
The GW75xx has a LIS2DE12TR 3-axis accelerometer on the I2C bus with an
interrupt pin. Add it to the device-tree.
Signed-off-by: Tim Harvey <tharvey@...eworks.com>
----
v3: move reg directly after compatible and before pinctrl
v2: make sure compatible is on top and vendor specific props are at the
end per:
https://docs.kernel.org/devicetree/bindings/dts-coding-style.html
