Hm, there has been no response to the comments in more than a month, also
the series depends on another ('Split SDM845 interconnect nodes and
consolidate RPMh support' https://patchwork.kernel.org/project/linux-arm-msm/list/?series=238831),
even though that isn't mentioned anywhere.

IIUC the interconnect configuration isn't strictly required to get the
video codec to work. I wonder if it would make sense to respin this
series to remove the interconnect properties. They could be added in a
separate patch after the ICC support has landed.

Dikshita/Bjorn, what do you think?
