Subject: [PATCH] ARM: tegra: gpio: Use engineering names in DT compatible property

Engineering names are more stable than marketing names. Hence, use them
for Device Tree compatible properties instead.

Grant, This patch is physically against devicetree/arm, but also makes
sense to apply to devicetree/test. This patch will cause conflicts
somewhere, given you previously posted a patch to move gpio.c into
drivers/gpio.

 NVIDIA Tegra 2 GPIO controller
 
 Required properties:
-- compatible : "nvidia,tegra250-gpio"
+- 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.
