Rather if there is a sibling15 of the BCI node which is compatible with "ti,twl4030-usb", then that is used16 to determine when and how use USB power for charging.17 18maintainers:19 - Sebastian Reichel <sre@kernel.org>20 21allOf:22 - $ref: power-supply.yaml#23 24properties:25 compatible:26 const: ti,twl4030-bci27 28 interrupts:29 minItems: 230 maxItems: 231 32 ti,bb-uvolt:33 $ref: /schemas/types.yaml#/definitions/uint3234 description: microvolts for charging the backup battery35 36 ti,bb-uamp:37 $ref: /schemas/types.yaml#/definitions/uint3238 description: microamps for charging the backup battery39 40 io-channels:41 items:42 - description: Accessory Charger Voltage Channel43 44 io-channel-names:45 items:46 - const: vac47 48 bci3v1-supply:49 description: 3.1V USB regulator50 51required:52 - compatible53 - interrupts54 55additionalProperties: false56 57examples:58 - |59 pmic {60 charger {61 compatible = "ti,twl4030-bci";62 interrupts = <9>, <2>;63 ti,bb-uvolt = <3200000>;64 ti,bb-uamp = <150>;65 io-channels = <&twl_madc 11>;66 io-channel-names = "vac";67 };68 };69
