Using vendor name in device name is just confusing, so: samsung,exynos2200-eusb2-phy However the description should include it, e.g. Samsung Exynos2200 eUSB2 phy, based on Synopsys eUSB2 IP block, .... ... > +additionalProperties: false > + > +examples: > + - | > + usb_hsphy: phy@10ab0000 { > + compatible = "samsung,exynos2200-snps-eusb2-phy"; > + reg = <0x10ab0000 0x10000>; > + #phy-cells = <0>; > + > + clocks = <&cmu_hsi0 7>, > + <&cmu_hsi0 5>, > + <&cmu_hsi0 8>; These should be aligned with opening < With above: Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Best regards, Krzysztof
