driver dcss in drm. Patch #2 makes that driver use the new function.
I compiled this successfully but unfortunately don't have the hardware
to test it for dcss.
So you might want to have a closer look.

Remove the unused drm_connector_helper_get_modes_from_ddc()
function. Most drivers should probably have this functionality split to
detect and get modes parts, so the helper is not the best abstraction.

Convert mgag200 to use struct drm_edid directly, and drop
drm_connector_helper_get_modes_from_ddc(), as suggested by Thomas.
This supersedes [1].

This patchset aims to add support for additional buffer YUV formats.
More specifically, it adds support to:
Semi-planar formats:
- NV12
- NV16
- NV24
- NV21
- NV61
- NV42
Planar formats:
- YUV440
- YUV422
- YUV444
- YVU440
- YVU422
- YVU444
These formats have more than one plane, and most have

Add support to multy-planar formats by adding an index argument to the
framebuffer data access functions.
Also, give all the planes to the conversion functions. This, for now,
