Subject: [PATCH v8 1/2] dt-bindings: iio: accel: Add bmi088 accelerometer bindings
Date:   Mon, 25 Jan 2021 16:07:31 +0100
Message-Id: <20210125150732.23873-1-mike.looijmans@topic.nl>
Precedence: bulk

This adds the device-tree bindings for the Bosch Sensortec BMI088 IMU,
the accelerometer part.

Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>

---

Changes in v8:
Add spi-max-frequency: true

Changes in v7:
Add additionalProperties
Change bmi088_accel to bmi088-accel
Add interrupt-names and adjust description

Changes in v6:
I't been almost a year since the last commit, sorry...
Fixed the yaml errors
Add interrupt, vdd and vddio properties

Changes in v5:
submit together with driver code as patch series

Changes in v2:
convert to yaml format
