Subject: [PATCH 0/4] DVFS support for dpu and dsi

These patches add DVFS support for DPU and DSI. Where posted
earlier as part of a series with multiple different drivers [1]
I have split them into specific driver changes in order to avoid
confusion on dependencies. Also added the corresponding device tree
changes for sdm845 and sc7180 platforms.

These patches have no other dependency and will need to be merged in
via the MSM DRM tree.

DT patches will need to land via the msm tree.
