This is not really a question about linux using it or not.

The PHY registers happens to be at the beginning of a large zone containing
interleaved system registers (mainly clocks, power management, PHY control..).

The goal is to model it the same way as the other "features" of this zone,
like Documentation/devicetree/bindings/clock/amlogic,gxbb-clkc.txt
and Documentation/devicetree/bindings/power/amlogic,meson-ee-pwrc.yaml
and have a coherent bindings scheme.
