Can you provide an updated list of dependencies because it seems this
patch depends on more than the patch aboves. I applied the related
patch series above but there is still missing node
ERROR (phandle_references): /soc/mdp-rdma0@14001000: Reference to
non-existent node or label "scp"
ERROR (phandle_references): /soc/mdp-rdma0@14001000: Reference to
non-existent node or label "mutex"

It would be even better if you could provide a branch with all the
dependencies included.

The kernel is not booting anymore when the 4 clocks above are added,
if I remove them I can boot again. See the following log:
