Hello,

This patch series adds support for 16 missing RGB formats to the DU
driver. To do is, the formats are first added to the VSP1 driver.
Patches 1/9 to 3/9 define those formats in the V4L2 API, patches 4/9 to
6/9 add them to the VSP driver, and patches 7/9 to 9/9 finally add them
to the DU driver.

There's nothing very special here, but those patches are likely very
error-prone due to the many instances of very similar constructs. I
would thus appreciate careful review.

The new V4L2 4CCs match (or at least should match if I haven't made any
mistake) the DRM 4CCs, but the names of the format macros differ in
order to stick to the V4L2 naming scheme.

This series touches both V4L2 and DRM drivers. I think it would be
easier to merge it through the V4L2 tree, as the changes on the DRM side
as minimal (see patches 7/9 to 9/9). Would that be OK with you ? I will
of course make sure to avoid conflict with the R-Car DU patches already
merged in your tree.
