Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade This patch series was applied (using b4) to base: Base: attempting to guess base-commit...

This SoC has a single USB 3.1 DRD combo phy and three USB2.0 only DRD phy controllers - Combo phy supports USB3.1 SSP+(10Gbps) protocol and is backwards compatible to the USB3.0 SS(5Gbps). 'Add-on USB2.0' phy is added to support USB2.0 HS(480Mbps), FS(12Mbps) and LS(1.5Mbps) data rates. These two phys are combined to form a combo phy as mentioned below.
