[PATCH 2/7] ARM: dts: overo: Add LIS33DE accelerometer

Florian Vaussard florian.vaussard at epfl.ch
Tue Mar 11 08:20:30 EDT 2014


The LIS33DE accelerometer is used on several Gumstix expansion boards,
thus add the DT node to omap3-overo-common-peripherals.dtsi.

For the boards that do not have the accelerometer (like Tobi), mark the
status as disabled.
