This patch set is a RFC about a backlight framework. The purpose of this framework is mainly to allow to add easily a support for a backlight with the possibility of setting brightness directly from the barebox shell using the brightness parameter. An implementation is provided for i.MX23 by using the PWM. It was tested on a custom i.MX23 base board.
