Allocate DSC inversely for non built-in displays to avoid Quad DSC can't be contiguous reserved as the below scenario. Use case: Primary display with 2 DSC, and DP display can support 8K@60 with 4 DSC and 4k@60 with 2 DSC. --> when both display are in powered off, all DSC blocks are free. --> enable DP display with 4k@60. DSC 0/1 is allocated by DP display --> enable primary display. DSC 2/3 is allocated by primary display. --> switch DP display to 8K@60 DSC 0/1 + DSC 4/5 are allocated by DP display. But the DSC must be contiguous allocated for Quad pipe. Change-Id: I465c115bb7ec775483dc6a984306a9aa51750b14 Signed-off-by: Lei Chen <quic_chenlei@quicinc.com>
