1 TWL BCI (Battery Charger Interface) 2 3 The battery charger needs to interact with the USB phy in order 4 to know when charging is permissible, and when there is a connection 5 or disconnection. 6 7 The choice of phy cannot be configured at a hardware level, so there 8 is no value in explicit configuration in device-tree. Rather 9 if there is a sibling of the BCI node which is compatible with 10 "ti,twl4030-usb", then that is used to determine when and how 11 use USB power for charging. 12 13 Required properties: 14 - compatible: 15 - "ti,twl4030-bci" 16 - interrupts: two interrupt lines from the TWL SIH (secondary 17 interrupt handler) - interrupts 9 and 2. 18 19 Optional properties: 20 - ti,bb-uvolt: microvolts for charging the backup battery. 21 - ti,bb-uamp: microamps for charging the backup battery. 22 23 Examples: 24 25 bci { 26 compatible = "ti,twl4030-bci"; 27 interrupts = <9>, <2>; 28 ti,bb-uvolt = <3200000>; 29 ti,bb-uamp = <150>; 30 };
