TODO:
- get DRM Maintainer review for this code
-- Wait for common display framework to hit mainline and update the IPU
- driver to use it. This will most probably make changes to the devicetree
- bindings necessary.
-- Factor out more code to common helper functions
- decide where to put the base driver. It is not specific to a subsystem
and would be used by DRM/KMS and media/V4L2
Missing features (not necessarily for moving out of staging):
-- Add i.MX6 HDMI support
- Add support for IC (Image converter)
- Add support for CSI (CMOS Sensor interface)
- Add support for VDIC (Video Deinterlacer)
