TGL supports DC3CO only on PipeA in LPSP mpde, so DC3CO doesn't depends on TGL PSR "Transcoder B" feature. B.Specs:49196 DC3CO requirements: *Audio codec idle and disabled. *External displays disabled. WD transcoders and DP/HDMI transcoders must be disabled. *Backlight cannot be driven from the display utility pin. It can be driven from the south display. *This feature should be enabled only in Display Video playback on eDP. *DC5 and DC6 not allowed when this feature is enabled. *PSR2 deep sleep disabled (PSR2_CTL Idle Frames = 0000b) *Disable DC3co before mode set, or other Aux, PLL, and DBUF programming, and do not re-enable until after that programming is completed. *DC3co must not be enabled until after PSR2 is enabled. *DC3co must be disabled before PSR2 is disabled.
