[PATCH 1/3] dt-bindings: iio: imu: icm42607: Add devicetree binding

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add devicetree binding for the Invensense ICM42607 and Invensense
ICM42607P inertial measurement unit. This unit is a combined
accelerometer, gyroscope, and thermometer available via I2C or SPI.

This device is functionally very similar to the icm42600 series with a
very different register layout.
