[PATCH] pwm-backlight: add support for device tree gpio control

2013-09-03 Thread Mike Dunn
This patch adds support for controlling an arbitrary number of gpios to the pwm-backlight driver. This was left as a TODO when initial device tree support was added by Thierry a while back. This functionality replaces the callbacks that are passed in the platform data for non-DT cases. Users can
