I don't seem to see a cover letter for this series.

Eh, there are a fair number of differences between the MDSS versions
for 8998 and 845.

Probably a bigger question, why extend the DPU driver for 8998, when
the MDP5 driver already supports it[1]? The MDP/DPU split is pretty
dumb, but I don't see a valid reason for both drivers supporting the
same target/display revision. IMO, if you want this support in DPU,
remove it from MDP5.
