No, you are misunderstanding how these work. 'contains' means at least one entry in an array passes with the subschema. In this case, 'renesas,usb2-phy-r7s9210' must appear somewhere in the 'compatible' values. (Before, it said *every* entry must be 'renesas,usb2-phy-r7s9210'.) As there is a fallback compatible, we need 'contains'. > > --- a/Documentation/devicetree/bindings/pinctrl/renesas,pfc.yaml > > +++ b/Documentation/devicetree/bindings/pinctrl/renesas,pfc.yaml > > @@ -76,11 +76,10 @@ required: > > if: > > properties: > > compatible: > > - items: > > - enum: > > - - renesas,pfc-r8a73a4 > > - - renesas,pfc-r8a7740 > > - - renesas,pfc-sh73a0 > > + enum: > > + - renesas,pfc-r8a73a4 > > + - renesas,pfc-r8a7740 > > + - renesas,pfc-sh73a0 > > Missing "contains"? No. In this case, 'compatible' is always a single entry, so no 'contains' needed (but would work). If compatible is one of these 3 strings, then the 'if' is true. The original way would actually work in this case (i.e. is valid json-schema), but we require 'items' to have a size (maxItems/minItems) in our meta-schema. Rob
