Add a paragraph explaining that the default behavior for areas which
are not covered by planes or where planes are blending with the CRTC
background, is black.
This is alluded to in the "pixel blend mode" property docs, but not
called out explicitly.

For bitmasks you probably want to explicitly specify their length by using
u32/u64 types. This probably applies elsewhere too.

This patch adds HDCP 1.x support to msm DP connectors using the new HDCP
helpers.

This patch adds the register ranges required for HDCP key injection and
HDCP TrustZone interaction as described in the dt-bindings for the
sc7180 dp controller. Now that these are supported, change the
compatible string to "dp-hdcp".

Above, you're checking
if (new_state_lut_size != gamma_size && new_state_lut_size != gamma_lut_size)
fail;
doesn't that imply that gamma_size and gamma_lut_size must always be equal? If
so, perhaps turf this new state and rename degamma_lut_size to degamma_size to
be consistent.
De-duping this and initializing crtc->gamma_size in the initialization would
mean the if (crtc->gamma_size) check in drm_crtc_supports_legacy_check() is no
longer useful (and possibly other similar checks), so some care will need to be
taken to avoid regression. I think the effort is worthwhile to avoid introducing
new state.

from amdgpu_dm_update_crtc_color_mgmt() is not possible to remove,
you could replace it with a call to the new helper function. And if _that_ is
not possible, please make amdgpu_dm_verify_lut_sizes() static :-)

encoder->commit() was being misused because there were some global
resources which needed to be tweaked in encoder->enable() which were not
accessible in dpu_encoder.c. That is no longer true and the redirect
serves no purpose any longer. So remove the indirection.
