   1 TI BQ24735 Charge Controller
   2 ~~~~~~~~~~
   3
   4 Required properties :
   5  - compatible : "ti,bq24735"
   6
   7 Optional properties :
   8  - interrupts : Specify the interrupt to be used to trigger when the AC
   9    adapter is either plugged in or removed.
  10  - ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter
  11    presence. This is a Host GPIO that is configured as an input and
  12    connected to the bq24735.
  13  - ti,charge-current : Used to control and set the charging current. This value
  14    must be between 128mA and 8.128A with a 64mA step resolution. The POR value
  15    is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
  16    about the ChargeCurrent (0x14h) register.
  17  - ti,charge-voltage : Used to control and set the charging voltage. This value
  18    must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
  19    is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
  20    about the ChargeVoltage (0x15h) register.
  21  - ti,input-current : Used to control and set the charger input current. This
  22    value must be between 128mA and 8.064A with a 128mA step resolution. The
  23    POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
  24    more information about the InputCurrent (0x3fh) register.
  25  - ti,external-control : Indicates that the charger is configured externally
  26    and that the host should not attempt to enable/disable charging or set the
  27    charge voltage/current.

  31         bq24735@9 {
  32                 compatible = "ti,bq24735";
  33                 reg = <0x9>;
  34                 ti,ac-detect-gpios = <&gpio 72 0x1>;
  35         }
