[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.
