PSR2 vsc revision number hb2( as per table 6-11)is updated to 4 or 5 based on Y cordinate and Colorimetry Format as below 04h = 3D stereo + PSR/PSR2 + Y-coordinate. 05h = -3D stereo- + PSR/PSR2 + Y-coordinate + Pixel Encoding/Colorimetry Format indication. 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.
