mdio.yaml wrong parser mdio controller's address instead phy's address when mdio-mux exist.
For example: mdio-mux-emi1@54 { compatible = "mdio-mux-mmioreg", "mdio-mux";
mdio@20 { reg = <0x20>; ^^^ This is mdio controller register
ethernet-phy@2 { reg = <0x2>; ^^^ This phy's address }; }; };
Only phy's address is limited to 31 because MDIO bus defination.
But CHECK_DTBS report below warning:
arch/arm64/boot/dts/freescale/fsl-ls1043a-qds.dtb: mdio-mux-emi1@54: mdio@20:reg:0:0: 32 is greater than the maximum of 31
The reason is that "mdio@20" match "patternProperties: '@[0-9a-f]+$'" in mdio.yaml.
Change to '^(?!mdio@).*@[0-9a-f]+$' to avoid match parent's mdio controller's address.
