Subject: [PATCH 200/277] drm/vc4: Use .pixel_order instead of custom
|
|
.flip_cbcr
|
|
|
|
The hardware has enums for altering the Cr and Cb order,
|
|
so use this instead of having a flag which swaps the
|
|
order the pointers are presented to the hardware
|
|
(that only worked for 3 plane formats anyway).
|
|
|
|
Explicitly sets .pixel_order in each case, rather than
|
|
relying on then default XYCBCR order being a value 0.
