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. + +Required properties: +- compatible: + - "ti,twl4030-bci" +- interrupts: two interrupt lines from the TWL SIH (secondary + interrupt handler) - interrupts 9 and 2. + +Optional properties: +- ti,bb-uvolt: microvolts for charging the backup battery. +- ti,bb-uamp: microamps for charging the backup battery. + +Examples: + +bci { + compatible = "ti,twl4030-bci"; + interrupts = <9>, <2>; + ti,bb-uvolt = <3200000>; + ti,bb-uamp = <150>; +}; |
