   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 };
