Subject: [PATCH 1/3] iio: accel: bmc150-accel: Add DT bindings
Date: Sun, 1 Nov 2020 13:28:31 +0100 [thread overview]
Message-ID: <20201101122833.1111424-1-linus.walleij@linaro.org> (raw)
These accelerometers have bindings used in the kernel and
several device trees but no proper bindings documentation.
Add it.
Also add a compatible for the BMA222 that I am right now
adding support for in the driver.
