[RFC/PATCH 0/2] Backlight support

[Gregory CLEMENT]

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.
