drm: add helper functions for YCBCR420 handling
This patch adds helper functions for YCBCR 420 handling.
These functions do:
- check if a given video mode is YCBCR 420 only mode.
- check if a given video mode is YCBCR 420 also mode.
V2: Added YCBCR functions as helpers in DRM layer, instead of
keeping it in I915 layer.
V3: Added handling for YCBCR-420 only modes too.
V4: EXPORT_SYMBOL(drm_find_hdmi_output_type)
V5: Addressed review comments from Danvet:
- %s/drm_find_hdmi_output_type/drm_display_info_hdmi_output_type
- %s/drm_can_support_ycbcr_output/drm_display_supports_ycbcr_output
- %s/drm_can_support_this_ycbcr_output/
drm_display_supports_this_ycbcr_output
- pass drm_display_info instead of drm_connector for consistency
- For drm_get_highest_quality_ycbcr_supported doc, move the variable
description above, and then the function description.
V6: Add only YCBCR420 helpers (Ville)
V7: Addressed review comments from Ville
- Remove cea_vic_valid() check.
- Fix indentation.
- Make input parameters to helpers, const.
