[PATCH v3 0/2] ARM: dts: n900: use iio driver for accelerometer

[Sicelo A. Mhlongo]

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

[Sicelo A. Mhlongo]

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

[Sicelo A. Mhlongo]

The 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
