   1 Binding for TI bq25890 Li-Ion Charger
   2
   3 Required properties:
   4 - compatible: Should contain one of the following:
   5     * "ti,bq25890"
   6 - reg: integer, i2c address of the device.
   7 - ti,battery-regulation-voltage: integer, maximum charging voltage (in uV);
   8 - ti,charge-current: integer, maximum charging current (in uA);
   9 - ti,termination-current: integer, charge will be terminated when current in
  10     constant-voltage phase drops below this value (in uA);
  11 - ti,precharge-current: integer, maximum charge current during precharge
  12     phase (in uA);
  13 - ti,minimum-sys-voltage: integer, when battery is charging and it is below
  14     minimum system voltage, the system will be regulated above
  15     minimum-sys-voltage setting (in uV);
  16 - ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
  17 - ti,boost-max-current: integer, maximum allowed current draw in boost mode
  18     (in uA).
  19
  20 Optional properties:
  21 - ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz,
  22     otherwise 1.5MHz;
  23 - ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the
  24     input current will be the lower between the resistor setting and the IINLIM
  25     register setting;
  26 - ti,thermal-regulation-threshold: integer, temperature above which the charge
  27     current is lowered, to avoid overheating (in degrees Celsius). If omitted,
  28     the default setting will be used (120 degrees);
