Hi, fixed reg-error by using 32bit-address in example, in my test output is clean. +++ b/Documentation/devicetree/bindings/phy/rockchip,pcie3-phy.yaml @@ -68,7 +68,7 @@ examples: #include <dt-bindings/clock/rk3568-cru.h> pcie30phy: phy@fe8c0000 { compatible = "rockchip,rk3568-pcie3-phy"; - reg = <0x0 0xfe8c0000 0x0 0x20000>; + reg = <0xfe8c0000 0x20000>; i hope yours is clean too regarding data-lanes instead of own lane-map, Peter and me only find this in special bindings outside the phy-"namespace" like this. https://elixir.bootlin.com/linux/v5.18-rc7/source/Documentation/devicetree/bindings/media/video-interfaces.yaml#L157 do you mean converting this binding and add it there and base out binding on it? https://elixir.bootlin.com/linux/v5.18-rc7/source/Documentation/devicetree/bindings/phy/phy-bindings.txt regards Frank
