DRM_MODE_BLEND_PIXEL_NONE ignores an alpha channel.
Rcar-du driver supports only 3 formats with an alpha channel
(DRM_FORMAT_ARGB1555, DRM_FORMAT_ARGB and DRM_FORMAT_ARGB). We
simply override the format passed to VSP1 for blending with the pixel
format without alpha channel.
Suggested-by:
To support DRM blend mode in R-Car DU driver, we must be able to pass
a plane with the premultiplied alpha. Adding a new property to
vsp1_du_atomic_config allows the R-Car DU driver to pass the
premultiplied alpha plane.

R-Car DU driver implicitly supports DRM_MODE_BLEND_COVERAGE only.
This adds a support for DRM_MODE_BLEND_PREMULTI. As a consequence,
DRM_MODE_BLEND_PREMULTI becomes the default. If DRM_MODE_BLEND_COVERAGE
is desired, it should be set explicitly.
This behavior comes from how DRM blend mode is suppo
The series of patches adds support for DRM pixel blend mode to R-Car DU
driver. The current R-Car DU implicitly supports "Coverage" only.
Unfortunately, this changes the default blending mode of R-Car DU to
"Pre-multiplied" which is the default when pixel blend mode is
supported.

Whenever we are not able to get enough timeslots
for required PBN, let's try to allocate those
using DSC, just same way as we do for SST.
v2: Removed intel_dp_mst_dsc_compute_config and refactored
intel_dp_dsc_compute_config to support timeslots as a

Adding DP DSC register definitions, we might need for further
DSC implementation, supporting MST and DP branch pass-through mode.
