[PATCH v10 2/2] drm/i915: Adding YUV444 packed format support for skl+

2018-09-07T08:45:20Z

PLANE_CTL_FORMAT_AYUV is already supported, according to hardware
specification.

v2: Edited commit message, removed redundant whitespaces.

v3: Fixed fallthrough logic for the format switch cases.

v4: Yet again fixed fallthrough logic, to reuse code from other case
labels.

v5: Started to use XYUV instead of AYUV, as we don't use alpha.

v6: Removed unneeded initializer for new XYUV format.

v7: Added scaling support for DRM_FORMAT_XYUV

v8: Edited commit message to be more clear about skl+, renamed
PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
doesn't support per-pixel alpha. Fixed minor code issues.

v9: Moved DRM format check to proper place in intel_framebuffer_init.

v10: Added missing XYUV format to sprite planes for skl+.
