drm/i915: Add CRTC output format YCBCR 4:2:0
Currently, we are using a bool in CRTC state (state->ycbcr420),
to indicate modeset, that the output format is YCBCR 4:2:0. Now in
order to support other YCBCR formats, we will need more such flags.
This patch adds a new enum parameter for YCBCR 4:2:0 outputs, in the
CRTC output formats and then plugs it during the modeset.
V3: Added this patch in the series, to address review comments from
second patchset.
V4: Added r-b from Maarten (on v3)
Addressed review comments from Ville:
- Change the enum name to intel_output_format.
- Start the enum value (INVALID) from 0 instaed of 1.
- Set the crtc's output_format to RGB in encoder's compute_config.
V5: Broke previous patch 1 into two parts,
- first patch to add CRTC output format in general
- second patch (this one) to add YCBCR 4:2:0 output
format specifically.
- Use ARRAY_SIZE(format_str) for output format validity check (Ville)
V6: Added a separate function to calculate crtc_state->output_format, and
calling it from various get_config function (Fix CI build warning)
V7: Fixed checkpatch warnings for alignment
V8: Rebase
V9: Rebase
V10: Rebase
V11: Addressed review comments from Ville:
- Change check for CRTC output format from > ARRAY_SIZE to >= ARRAY_SIZE.
- Check for values < INTEL_OUTPUT_FORMAT_RGB is unnecessary.
- No need to get CRTC YCBCR config, for pre-BDW functions.
Added Ville's r-b.
