Enable tegra based keyboard controller and populate the key mapping for whistler. With this patch, HOME, BACK, POWER and MENU keys will work. Still other keys which are in ROW3 and ROW4 will not work as it conflicts with KBC pins on SDIO2 pinmux. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> --- Stephen, Not tested the change but I reviewed all possible configuration like pinmux and the parameter as per the downstream.
