You only need to add the rk3562 only to one of those blocks.
The bottom one contains the snps,dwmac-4.20a element and looking at the
soc devicetree, it seems that is the correct one:
	compatible = "rockchip,rk3562-gmac", "snps,dwmac-4.20a";

So you only need the second addition where the newer socs are in the enum.

This should get mentioned in the commit message

Usual comments... we see what you did here. No need to repeat it in

So all devices now can have 4 clocks? No, constrain all variants.
