Subject: [RFC/PATCH 0/2]  Backlight support
Date: Thu, 06 Oct 2011 10:05:07 +0200	[thread overview]
Message-ID: <4E8D6133.8080604@free-electrons.com> (raw)

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.

All this commits are done to be applied on top of this git repository :

  git://git.pengutronix.de/git/barebox.git master

The HEAD of this git repository, when I created this patch, was:
commit 71e806048e5a370fbcabf5441de33bd3f083903a
login: correct a typo in command description
