This should be SoC specific, or also have an SoC specific string.

Is this common or vendor specific. The former should refer to a common
doc. The latter should have a vendor prefix. I'd think the former makes
sense here.
But then why do you need this and max-frame-size?

+For the child phy

+- compatible "ethernet-phy-ieee802.3-c22" is needed
+- device_type "ethernet-phy"
+- reg: phy address

+ reg = <0 0x31600000 0x10000>, <0 0x31618000 0x4000>, <0 0x3161c000 0x4000>;
+ interrupts = <0 163 0x4>;
+ clocks = <&clk_alw_0_8>;
+ phy-mode = "rgmii";
