linux-toradex.git/drivers/video/sh_mobile_meram.c, branch v3.0.78 Linux kernel for Apalis and Colibri modules fbdev: sh_mobile_meram: Correct pointer check for YCbCr chroma plane 2011-06-24T07:40:28+00:00 Damian Hobson-Garcia dhobsong@igel.co.jp 2011-06-22T07:46:25+00:00 06c8a6a3e40265ff580428bbf51991617477f65b The check was intended to test if we have a valid pointer to write into, but it mistakenly checks the pointer contents instead. Since a valid pointer is mandatory for the chroma data if a YCbCr format is used, the pointer check has been removed.

sh_mobile_meram: Add support for NV24 framebuffers 2011-05-23T07:06:26+00:00 Damian dhobsong@igel.co.jp 2011-05-18T11:10:08+00:00 3fedd2ac7662a10ab2973d3b6f11cdce87b7171a Since the NV24 framebuffer has a CbCr plane that is twice as wide as the Y plane, it needs to be handled as a special case.

sh_mobile_meram: MERAM framework for LCDC 2011-05-23T07:06:24+00:00 Damian dhobsong@igel.co.jp 2011-05-18T11:10:07+00:00 7caa4342ca5b37d2d178b464c16badd4228b3b7b Based on the patch by Takanari Hayama <taki@igel.co.jp> Adds support framework necessary to use Media RAM (MERAM) caching functionality with the LCDC. The MERAM is accessed through up to 4 Interconnect Buffers (ICBs). ICB numbers and MERAM address ranges to use are specified in by filling in the .meram_cfg member of the LCDC platform data Signed-off-by: Damian Hobson-Garcia <dhobsong@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
