   2
   3 Required properties:
   4 - compatible: Should contain one of the following:
   5  * "ti,bq24150"
   6  * "ti,bq24150"
   7  * "ti,bq24150a"
   8  * "ti,bq24151"
   9  * "ti,bq24151a"
  10  * "ti,bq24152"
  11  * "ti,bq24153"
  12  * "ti,bq24153a"
  13  * "ti,bq24155"
  14  * "ti,bq24156"
  15  * "ti,bq24156a"
  16  * "ti,bq24158"
  17 - reg:                     integer, i2c address of the device.
  18 - ti,current-limit:        integer, initial maximum current charger can pull
  19                            from power supply in mA.
  20 - ti,weak-battery-voltage: integer, weak battery voltage threshold in mV.
  21                            The chip will use slow precharge if battery voltage
  22                            is below this value.
  23 - ti,battery-regulation-voltage: integer, maximum charging voltage in mV.
  24 - ti,charge-current:       integer, maximum charging current in mA.
  25 - ti,termination-current:  integer, charge will be terminated when current in
  26                            constant-voltage phase drops below this value (in mA).
  27 - ti,resistor-sense:       integer, value of sensing resistor in milliohm.
  28
  29 Optional properties:
  30 - ti,usb-charger-detection: phandle to usb charger detection device.
  31                             (required for auto mode)
