From: Quentin Schulz <quentin.schulz@xxxxxxxxxxx> If DP_TEST_COLOR_FORMAT_RAW_Y_ONLY is set, if MISC0 color format is DP_COLOR_FORMAT_RGB and all other bits are 0, then color format is actually Y-Only. If DP_TEST_COLOR_FORMAT_RAW_Y_ONLY is set, if MISC0 color format is DP_COLOR_FORMAT_YCbCr422, DP_TEST_DYNAMIC_RANGE_CEA is not set and chosen ITU is 601, then color format is actually RAW. If DP_TEST_VSC_SDP is set, then DP_TEST_COLOR_FORMAT_RAW_Y_ONLY, DP_TEST_COLOR_FORMAT, DP_TEST_DYNAMIC_RANGE_CEA, DP_TEST_YCBCR_COEFFICIENTS and DP_TEST_BIT_DEPTH are ignored and we should use VSC SDP for setting the colorimetry. This is used for Y420.
