Has anyone been able to map control of the backlight (GPIO145_PWM10)
to /sys/class/gpio/? I am already able to control screen blanking
(GPIO144_PWM9, I believe) through /sys/class/gpio/gpio144 and would
like to do the same with the backlight (/sys/class/gpio/gpio145?) to
at least turn it on and off.
I am using Overo Earth on a Palo43 board. Do I need to enable
additional kernel modules? I tried enabling "Lowlevel Backlight
controls" in Backlight & LCD device support but this did not seem to
Thanks a lot for any suggestions.
