I don't see this warning locally. Are you using updated dt-schema? reg
is not necessary gpio-mux as per gpio-mux.yaml

Please add them to appropriate schema as necessary

No, pinctrl nodes need to end in -pins. All TI boards have been updated
to new schema [0] and sysconfig tool on dev.ti.com/sysconfig generates
appropriately. Please fix

Sorry, I didnt get what's the issue wrt cdns,phy-type ?


Note, I really don't want to accept patches that add new dtbs_check
issues especially for nodes that already have YAML bindings. Please
update the .yaml files as necessary.
