Thank you for checking as I didn't have the DTS close (and it seems
SC7180 would have supported this, but no).  I did check other SoCs in
the DPU 6.x range that are currently floating in my tree and on the
list, which do need their DSC 1.1 block added (both a single block at
0x81000 downstream, 0x80000 upstream), if you can in a resend Konrad:

DPU 6.4 in SM6350: https://lore.kernel.org/linux-arm-msm/20230411-topic-straitlagoon_mdss-v3-6-9837d6b3516d@linaro.org/
DPU 6.9 in SM6375: https://lore.kernel.org/linux-arm-msm/20230411-topic-straitlagoon_mdss-v3-8-9837d6b3516d@linaro.org/

Thanks!
