[PATCH 1/3] dt-bindings: Add InvenSense ICM-42370-p accelerometer

[Kanak Shilledar]

ICM42370P is a 3-axis accelerometer. The device can support
I2C, SPI and I3C. Add the supporting devicetree documentation for I2C as
we have only tested using I2C protocol and leave the reset for future
work.

The device supports VDD and VDDIO operating range of 1.71V to 3.6V.

+description: |
+  3-axis accelerometer MotionTracking device.
+
+  It supports I3C, I2C and SPI serial communication, has a 2.25kB FIFO
+  and 2 programmable interrupts with low-power wake-on-motion support.
+
+  It also has programmable filters and an embedded temperature sensor.
