The XPCS node requires board-level activation and PHY assignments, while the fixed-clock nodes are introduced to provide a static 125 MHz reference. > diff --git a/arch/arm64/boot/dts/rockchip/rk3568.dtsi b/arch/arm64/boot/d= ts/rockchip/rk3568.dtsi > --- a/arch/arm64/boot/dts/rockchip/rk3568.dtsi > +++ b/arch/arm64/boot/dts/rockchip/rk3568.dtsi > @@ -110,6 +110,51 @@ sata0: sata@fc000000 { > status =3D "disabled"; > }; > =20 > + xpcs: ethernet-pcs@fda00000 { > + compatible =3D "rockchip,rk3568-xpcs"; > + #address-cells =3D <1>; > + #size-cells =3D <0>; > + reg =3D <0x0 0xfda00000 0x0 0x200000>; > + clocks =3D <&cru PCLK_XPCS>, <&cru CLK_XPCS_EEE>; > + clock-names =3D "csr", "eee"; > + power-domains =3D <&power RK3568_PD_PIPE>; > + status =3D "disabled"; [Severity: Low] The commit message states that "dtbs_check only validates required properti= es for enabled nodes, so the SoC dtsi does not provide phys/phy-names". Is this assumption accurate? dt-schema evaluates all nodes against the required list regardless of the status property, unless the schema explicitly conditions the requirement. W= ill this omission cause make dtbs_check to throw validation errors for all RK35= 68 boards that leave the XPCS node disabled?

Since the 125 MHz reference clock is generated internally by the XPCS or Combo PHY, representing it as a fixed root oscillator appears to violate devicetree hardware modeling principles. Should the IP block that actually generates this clock act as the clock provider, instead of injecting a dummy fixed-clock node into the device tre= e? --=20 Sashiko AI review =C2=B7 https://sashiko.dev/#/patchset/20260919125119.2107= 089-1-coiaprant@gmail.com?part=3D5
