Maybe I'm looking at the wrong documentation, but it doesn't seem to exist
such clock on Milos. It does exist on SM8650 though. So maybe the TCSR CC
driver is not really that much compatible between these two platforms.

I take it that the UFS works. Maybe because the actual TCSR UFS clkref
is left enabled at boot?
