[PATCH] ARM: tegra: enable gpio-keys on dalmore

From: Laxman Dewangan
Date: Fri Jul 05 2013 - 08:38:17 EST


Dalmore have the keys mounted on board which are connected
to different pins of Tegra.

Add the keys entry in DTS file to enable key functionality.
This will enable KEY_POWER, KEY_HOME, KEY_VOLUMEUP and
KEY_VOLUMEDOWN.
