Good idea.

I'd love to, if you can tell me how to make sure the fck entry is mandatory. The following minItems: 1 maxItems: 4 items: enum: - fck - extal - dclkin.0 - dclkin.1 passes the checks, but would accept clock-names = "extal"; which is not valid. Your Documentation/devicetree/bindings/serial/renesas,scif.yaml bindings suffer from the same problem :-) > > +examples: > > + - | > > + #include <dt-bindings/clock/renesas-cpg-mssr.h> > > + #include <dt-bindings/power/r8a7795-sysc.h> > > + > > + lvds@feb90000 { > > + compatible = "renesas,r8a7795-lvds"; > > + reg = <0 0xfeb90000 0 0x14>; > > Examples are built with #{address,size}-cells = <1>.
