ARM: dts: n900: use iio driver for accelerometer
v3 cover ARM: dts: n900: use iio driver for accelerometer
The accelerometer in the N900 is now supported by the iio framework. This patch series makes the switch to the new compatible.
The iio framework does not support some of the extended properties in the previous driver, but the change is useful for modern userspace, which expects accelerometers to be exposed via iio.

PATCH v3 1/2 ARM: dts: n900: rename accelerometer node
Use generic node naming for lis302dl accelerometer, and drop its label that is not used anywhere else.

PATCH v3 2/2 ARM: dts: n900: use iio driver for accelerometer
In reply to Sicelo A. MhlongoThe accelerometer in the N900 is supported by the iio-framework since commit 8a7449d68670a8f9 ("iio: accel: add support for LIS302DL variant). This commit switches to it and updates node properties to match the bindings of the new compatible.

Applying these into omap-for-v6.3/dt thanks
