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.

I already pinged Rodrigo about this on irc, but drm core patches need an
ack from Dave for merging through a driver git tree. I've asked Rodrigo to
update the dim scripting to catch this so it won't happen in the future
again.

Thanks, Daniel
