This series fixes multiple issues I found out. Patch 1 fixes reporting colorimetry in AVI frame. Patch 2 sets scan mode to underscan which is in line with most other hdmi drivers. Patch 3 aligns RGB quantization to CEA 861 standard. Patch 4 reworks is_color_space_conversion(). Now it checks only if color space conversion is required. Patch adds separate function for checking if any kind of conversion is required.
Please take a look.
Best regards, Jernej
Changes from v2: - added tags - replaced patch 2 with patch 4 - renamed rgb conversion matrix and make hex lowercase - move logic for checking if rgb full to limited range conversion is needed to is_color_space_conversion() - reworked logic for csc matrix selection
