[PATCH] mbxfb: Add YUV video overlay support
This patch adds a way to create and use the video plane (YUV overlay) and scaling video scaling features of the chip. The overlay is configured, resized and modified using a device specific ioctl. Also included in this patch: - If no platform data was passed, print an error and exit instead of crashing. - Added a write_reg(_dly) macro. This improves readability when manipulating chip registers. (no more udelay() after each write). - Comments about some issues. Signed-off-by: Raphael Assenat <raph@8d.com> Cc: "Antonino A.
