[PATCH] dt-bindings: Drop unnecessary *-supply schemas properties - dri-devel - freedesktop.org experimental mailing list

21 Dec 2020

*-supply properties are always a single phandle, so binding schemas
don't need a type $ref nor 'maxItems'.
A meta-schema check for this is pending once these existing cases are
fixed.
