From 575001e40c9d10e63f2924649098e7c07d3985c7 Mon Sep 17 00:00:00 2001 From: Stefano Babic Date: Wed, 13 Oct 2010 12:16:35 +0200 Subject: MX51: Add IPU driver for video support The patch is a porting of the IPU Linux driver developed by Freescale to have framebuffer functionalities in u-boot. The port is based on kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f, as delivered by Freescale [i.MX BSP]. Most features are dropped from the original driver and only LCD support is the goal of this porting.
