NVIDIA Tegra 2 GPIO controller

Required properties:
- compatible : "nvidia,tegra20-gpio"
- #gpio-cells : Should be two. The first cell is the pin number and the
  second cell is used to specify optional parameters (currently unused).
- gpio-controller : Marks the device node as a GPIO controller.
gpio/tegra: add devicetree support Add support for decoding gpios from the device tree Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Olof Johansson <olof@lixom.net> 2011-06-15 20:54:14 +00:00			`NVIDIA Tegra 2 GPIO controller`

gpio/tegra: Use engineering names in DT compatible property Engineering names are more stable than marketing names. Hence, use them for Device Tree compatible properties instead.
