All DSI PHY/PLL drivers were referencing their VCO parent clock by a global name, most of which don't exist or have been renamed. These clock drivers seem to function fine without that except the 14nm driver for sdm6xx [1].
At the same time all DTs provide a "ref" clock as per the requirements of dsi-phy-common.yaml, but the clock is never used. This patchset puts that clock to use without relying on a global clock name, so that all dependencies are explicitly defined in DT (the firmware) in the end.
I can take this through clk tree if it helps avoid conflicts. There are some other patches to sdm660.c in the clk tree already.
