Shouldn't this just be
pattern: "^usb[23]-[0-3]$"
so that it matches the names that are used by the nvidia bindings?
We already have some inconsistency in that Amlogic uses a variant based
on the legacy names that needlessly includes "phy" in the names:
const: usb2-phy0
const: usb2-phy1
const: usb3-phy0
...
I don't think we should be introducing a third naming scheme here so I
suggest just following the nvidia bindings.
In that case, why don't we use "^usb[23]-phy[0-3]$". I think its close
to what we have on dwc3 core already today (usb2-phy/usb3-phy).
