IIUIC, they are actually Ethernet PHY signals. How is this supposed to work? The rest LGTM.

Currently, for the RX clocks, we get a > rate of 0 since they are external. So the link would not be provided by DT? If these clocks are inputs to the clock controller, they should be listed in the clock controller's clock{,-name}s' properties... > I haven’t written a prototype yet for the PHY driver to provide the > clocks, but the plan is to get the initial pieces in place and then > extend support for that. > > Is my understanding correct that the PHY should provide the clocks? Or > would you suggest a different approach? The Static Mux Control Registers (CPG_SSEL[01]) registers treat them as clock inputs. However, Figure 6.3-1 ("Block Diagram of the Ethernet Interface") shows the TX clocks are bidirectional, so they can be used as either inputs or outputs? On RGMII[1], RXC is an input (PHY-to-MAC), while TXC is an output (MAC-to-PHY). I'm a bit lost on how this works, and how to model and handle this...
