| Subject: ARM: shmobile: armadillo: Set backlight enable GPIO |
| |
| 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. |
