The choice of phy cannot be configured at a hardware level, so there is no value in explicit configuration in device-tree. Rather if there is a sibling of the BCI node which is compatible with "ti,twl4030-usb", then that is used to determine when and how use USB power for charging. maintainers: - Sebastian Reichel allOf: - $ref: power-supply.yaml# properties: compatible: const: ti,twl4030-bci interrupts: minItems: 2 maxItems: 2 ti,bb-uvolt: $ref: /schemas/types.yaml#/definitions/uint32 description: microvolts for charging the backup battery ti,bb-uamp: $ref: /schemas/types.yaml#/definitions/uint32 description: microamps for charging the backup battery io-channels: items: - description: Accessory Charger Voltage Channel io-channel-names: items: - const: vac bci3v1-supply: description: 3.1V USB regulator required: - compatible - interrupts additionalProperties: false examples: - | pmic { charger { compatible = "ti,twl4030-bci"; interrupts = <9>, <2>; ti,bb-uvolt = <3200000>; ti,bb-uamp = <150>; io-channels = <&twl_madc 11>; io-channel-names = "vac"; }; };
