A DP Source device is allowed to indicate the pixel encoding/colorimetry format to the DP Sink device with VSC SDP only when the DP Sink device supports it ( i.e.,VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the DPRX_FEATURE_ENUMERATION_LIST register (DPCD Address 02210h, bit 3; is set to 1). v2: (Jani) - Change DP_PSR_Y_COORDINATE to DP_PSR2_SU_Y_COORDINATE_REQUIRED. - Add DP_PSR2_SU_GRANULARITY_REQUIRED. - Change DPRX_FEATURE_ENUMERATION_LIST to DP_DPRX. - Add GTC_CAP and AV_SYNC_CAP, other bits in DPRX_FEATURE_ENUMERATION_LIST. v3: (Jani) - Add support for bits 7:4 and 1 as per DP v1.4 for DPRX_FEATURE_ENUMERATION_LIST.
