[PATCH v2 0/2] drm: vc4: Add support for additional 10/12/16bit YUV plane formats

[Dave Stevenson]

We'd been asked if the S01x YUV formats could be supported on Pi5 as some
software codecs produce them.
The answer was yes, so this patch adds them and the P01x formats.

Changes in v2:
- Swapped from adding an extra bool hvs6_only to having a min_gen for
  each format (suggested by Maíra)
- Link to v1: https://lore.kernel.org/r/20250724-drm-vc4-extra-formats-v1-1-67fa80597fad@raspberrypi.com

[PATCH v2 1/2] drm/vc4: plane: Flag formats as having a minimum generation

[Dave Stevenson]

The bool hvs5_only is now mis-named as they are also supported on
hvs6, and we're about to add formats that are only supported on
hvs6.

Change from a bool to an enum vc4_gen giving the minimum generation
that supports the format.

[PATCH v2 2/2] drm/vc4: plane: Add support for P01[026] and S01[026] formats

[Dave Stevenson]

There are now formats defined for 2-plane YUV420 at 10, 12,
and 16 bit depth using the most significant bits of the 16bit
word (P010, P012, and P016), and 3-plane YUV420 at those
depths using the least significant bits of the 16 bit word
(S010, S012, and S016).

VC4_GEN_6 can support all those formats although only using
at most 10bits of resolution.
Add them as supported formats for all planes, but filtered
by hardware revision.

I tested this with the Gstreamer MR from 1 and can confirm that the 
formats P010, P012, P016, S010 and S012 work as expected.

Unfortunately S016 is not supported by Gstreamer yet - however chances 
seem high that it works as well.

Thus the series is:

Thanks for testing.

In combination with my MR to libdrm/modetest to support these
formats[1], I'm happy that S016 works.
Your testing through Gstreamer gives me confidence that I haven't
messed up both my kernel patch and modetest setup in the same way :-)

Thanks again
