drm/i915: add config function for YCBCR420 outputs
This patch checks encoder level support for YCBCR420 outputs.
The logic goes as simple as this:
If the input mode is YCBCR420-only mode: prepare HDMI for
YCBCR420 output, else continue with RGB output mode.
It checks if the mode is YCBCR420 and source can support this
output then it marks the ycbcr_420 output indicator into crtc
state, for further staging in driver.
V2: Split the patch into two, kept helper functions in DRM layer.
V3: Changed the compute_config function based on new DRM API.
V4: Rebase
V5: Rebase
V6: Check and handle YCBCR420-only modes, discard the property
based approach (Ville)
V7: Addressed review comments from Ville
- add else case in 12BPC check.
- extract ycbcr420 state inside hdmi_12bpc_possible function.
V8: Addressed review comments from Ville
- Remove extra blank lines.
- Remove "HDMI" from the description of ycbcr420 state variable.
- Remove local variable, use crtc_state->ycbcr420 instead.
Added r-b from Ville.
V9: Rebase
V10: Added r-b from Imre
