Not optional given it's in required (which is correct) vcc-supply: true is enough for this as the voltage is probably only relevant for the person designing the board, not the dts author. > + > +required: > + - compatible > + - reg > + - interrupts > + - vcc-supply > + > +additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/interrupt-controller/irq.h> > + i2c { > + #address-cells = <1>; > + #size-cells = <0>; > + proximity@12 { > + compatible = "awinic,aw96103"; > + reg = <0x12>; > + interrupt-parent = <&gpio>; > + interrupts = <23 IRQ_TYPE_EDGE_FALLING>; > + vcc-supply = <&pp1800_prox>; > + }; > + };
