Generic node name, so at least "clock" prefix or suffix.

Are you sure the clock is a property of a SoC? IOW, it is physically on
the SoC? If not, define entire clock or its frequency by boards.

This looks undocumented.
Did you run `make dtbs_check`?

Reg is second property. Status goes last. The same in other nodes.

Undocumented compatible.

Missing reg. Did you run `make dtbs_check`? Did you actually check it
with dtc?

Node name: phy
The same in all other places. It can be also usb-phy and few others
