-Binding for TI bq25890 Li-Ion Charger
-
-This driver will support the bq25892, the bq25896 and the bq25890. There are
-other ICs in the same family but those have not been tested.
-
-Required properties:
-- compatible: Should contain one of the following:
- * "ti,bq25890"
- * "ti,bq25892"
- * "ti,bq25895"
- * "ti,bq25896"
-- reg: integer, i2c address of the device.
-- interrupts: interrupt line;
-- ti,battery-regulation-voltage: integer, maximum charging voltage (in uV);
-- ti,charge-current: integer, maximum charging current (in uA);
-- ti,termination-current: integer, charge will be terminated when current in
- constant-voltage phase drops below this value (in uA);
-- ti,precharge-current: integer, maximum charge current during precharge
- phase (in uA);
-- ti,minimum-sys-voltage: integer, when battery is charging and it is below
- minimum system voltage, the system will be regulated above
- minimum-sys-voltage setting (in uV);
-- ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
-- ti,boost-max-current: integer, maximum allowed current draw in boost mode
- (in uA).
-
-Optional properties:
-- ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz,
- otherwise 1.5MHz;
-- ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the
- input current will be the lower between the resistor setting and the IINLIM
- register setting;
-- ti,thermal-regulation-threshold: integer, temperature above which the charge
- current is lowered, to avoid overheating (in degrees Celsius). If omitted,
- the default setting will be used (120 degrees);
-- ti,ibatcomp-micro-ohms: integer, value of a resistor in series with
- the battery;
-- ti,ibatcomp-clamp-microvolt: integer, maximum charging voltage adjustment due
- to expected voltage drop on in-series resistor;
-
-Example:
-
-bq25890 {
- compatible = "ti,bq25890";
- reg = <0x6a>;
-
- interrupt-parent = <&gpio1>;
- interrupts = <16 IRQ_TYPE_EDGE_FALLING>;
-
- ti,battery-regulation-voltage = <4200000>;
- ti,charge-current = <1000000>;
- ti,termination-current = <50000>;
- ti,precharge-current = <128000>;
- ti,minimum-sys-voltage = <3600000>;
- ti,boost-voltage = <5000000>;
- ti,boost-max-current = <1000000>;
-
- ti,use-ilim-pin;
- ti,thermal-regulation-threshold = <120>;
