To put the regulator property up is also good. I'll refine it and resend the v3 patch series, Thanks. > > + description: BuckBoost converter regulator description. > > + type: object > > + $ref: regulator.yaml# > > + > > +required: > > + - compatible > > + - reg > > + > > +additionalProperties: false > > + > > +examples: > > + - | > > + i2c { > > + #address-cells = <1>; > > + #size-cells = <0>; > > + > > + rt6160@75 { > > + compatible = "richtek,rt6160"; > > + reg = <0x75>; > > + enable-gpios = <&gpio26 2 0>; > > + > > + buckboost { > > + regulator-name = "rt6160-buckboost"; > > + regulator-min-microvolt = <2025000>; > > + regulator-max-microvolt = <5200000>; > > + regulator-allowed-modes = <0 1>; > > + }; > > + }; > > + }; > > -- > > 2.7.4 > >
