drm/colorop: Add DRM_COLOROP_FIXED_MATRIX
Introduce DRM_COLOROP_FIXED_MATRIX, a new colorop type representing a
hardware that performs a fixed matrix operation.
Unlike CTM-based colorops, this block does not expose programmable
coefficients. Instead, userspace selects one of the predefined
hardware modes via a new FIXED_MATRIX_TYPE enum property. Supported modes
include common YCbCr->RGB and RGB709->RGB2020 conversions.
v5:
- Drop YCbCr limited to full and RGB709 to RGB2020 matrices
until we have non-IGT userspace that shows their use (Robert)
v4:
- Add limited-range YCbCr-RGB conversion matrix enums (Robert)
- Document matrix values (Pekka)
- Clarify RGB709 to RGB2020 is a full-range matrix (Pekka)
- Fix confusing "CSC preset" doc (Pekka)
v2:
- Naming changes (Pekka)
v3:
- Fix NC matrix enum name and string (Melissa)
- Rebase
