| |
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.
Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> --- Changes from V1: - Reorder the nodes
Changes from V2: - Remove unwanted line insertion. - Rename VolumeUP/Volume down lables.
