[PATCH v2] arm64: dts: imx8m*-venice-gw75xx: add Accelerometer device

From: Tim Harvey
Date: Mon Sep 09 2024 - 17:50:27 EST


The GW75xx has a LIS2DE12TR 3-axis accelerometer on the I2C bus with an
interrupt pin. Add it to the device-tree.

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
- fix typo in commit message
