+Binding for TI bq25890 Li-Ion Charger
+
+Required properties:
+- compatible: Should contain one of the following:
+ * "ti,bq25890"
+- reg: integer, i2c address of the device.
+- 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);
+
+Example:
+
+bq25890 {
+ compatible = "ti,bq25890";
+ reg = <0x6a>;
+
+ 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>;
+};
