Thus 'make dtbs_check' produces warnings like these: /arch/arm64/boot/dts/marvell/armada-3720-db.dtb: usb@58000 (marvell,armad= a3700-xhci): Unevaluated properties are not allowed ('marvell,usb-misc-reg'= was unexpected) from schema $id: http://devicetree.org/schemas/usb/generic-xhci.y= aml /arch/arm64/boot/dts/marvell/armada-3720-db.dtb: usb@5e000 (marvell,armad= a-3700-ehci): Unevaluated properties are not allowed ('marvell,usb-misc-reg= ' was unexpected) from schema $id: http://devicetree.org/schemas/usb/generic-ehci.y= aml Apart from the fact that the properties are not documented, those are not even used by any USB host drivers. At least 'git grep' says this: $ git grep -n 'marvell.usb-misc-reg' v7.0-rc2 v7.0-rc2:Documentation/devicetree/bindings/phy/marvell,armada-3700-utmi-p= hy.yaml:30: marvell,usb-misc-reg: v7.0-rc2:Documentation/devicetree/bindings/phy/marvell,armada-3700-utmi-p= hy.yaml:41: - marvell,usb-misc-reg v7.0-rc2:Documentation/devicetree/bindings/phy/marvell,armada-3700-utmi-p= hy.yaml:50: marvell,usb-misc-reg =3D <&usb2_syscon>; v7.0-rc2:arch/arm64/boot/dts/marvell/armada-37xx.dtsi:372: = marvell,usb-misc-reg =3D <&usb32_syscon>; v7.0-rc2:arch/arm64/boot/dts/marvell/armada-37xx.dtsi:383: = marvell,usb-misc-reg =3D <&usb32_syscon>; v7.0-rc2:arch/arm64/boot/dts/marvell/armada-37xx.dtsi:396: = marvell,usb-misc-reg =3D <&usb2_syscon>; v7.0-rc2:arch/arm64/boot/dts/marvell/armada-37xx.dtsi:406: = marvell,usb-misc-reg =3D <&usb2_syscon>; v7.0-rc2:drivers/phy/marvell/phy-mvebu-a3700-utmi.c:231: = "marvell,usb-misc-reg"); Due to this, drop the properties for now in order to get rid of the warnings. Given that the platform is quite old, and its support is mature enough, it is highly unlikely that the properties will be used in the future. Even, if that is not the case and the properties will be needed later by any chance, those can be added back along with the supporting code and with a proper documentation.
