Rather if there is a sibling 15 of the BCI node which is compatible with "ti,twl4030-usb", then that is used 16 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-bci 27 28 interrupts: 29 minItems: 2 30 maxItems: 2 31 32 ti,bb-uvolt: 33 $ref: /schemas/types.yaml#/definitions/uint32 34 description: microvolts for charging the backup battery 35 36 ti,bb-uamp: 37 $ref: /schemas/types.yaml#/definitions/uint32 38 description: microamps for charging the backup battery 39 40 io-channels: 41 items: 42 - description: Accessory Charger Voltage Channel 43 44 io-channel-names: 45 items: 46 - const: vac 47 48 bci3v1-supply: 49 description: 3.1V USB regulator 50 51required: 52 - compatible 53 - interrupts 54 55additionalProperties: false 56 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
