ARM: shmobile: armadillo: Set backlight enable GPIO (9a3beb04) · Commits · 戴 / test

The Armadillo 800 EVA panel module has a backlight enable signal connected to GPIO 61. Instead of requesting the GPIO in board code and setting it to a high level unconditionally, pass the GPIO number to the PWM backlight driver as the backlight enable GPIO. Signed-off-by:
