+TI BQ24190 Li-Ion Battery Charger
+
+Required properties:
+- compatible: contains one of the following:
+ * "ti,bq24190"
+ * "ti,bq24192i"
+- reg: integer, I2C address of the charger.
+- interrupts[-extended]: configuration for charger INT pin.
+
+Optional properties:
+- monitored-battery: phandle of battery characteristics devicetree node
+ The charger uses the following battery properties:
+ + precharge-current-microamp: maximum charge current during precharge
+ phase (typically 20% of battery capacity).
+ + charge-term-current-microamp: a charge cycle terminates when the
+ battery voltage is above recharge threshold, and the current is below
+ this setting (typically 10% of battery capacity).
+ See also Documentation/devicetree/bindings/power/supply/battery.txt
+- ti,system-minimum-microvolt: when power is connected and the battery is below
+ minimum system voltage, the system will be regulated above this setting.
+
+Notes:
+- Some circuit boards wire the chip's "OTG" pin high (enabling 500mA default
+ charge current on USB SDP ports, among other features). To simulate this on
+ boards that wire the pin to a GPIO, set a gpio-hog.
+
+Example:
+
+ bat: battery {
+ compatible = "simple-battery";
+ precharge-current-microamp = <256000>;
+ charge-term-current-microamp = <128000>;
+ // etc.
+ };
+
+ bq24190: charger@6a {
+ compatible = "ti,bq24190";
+ reg = <0x6a>;
+ interrupts-extended = <&gpiochip 10 IRQ_TYPE_EDGE_FALLING>;
+ monitored-battery = <&bat>;
+ ti,system-minimum-microvolt = <3200000>;
+ };
+
+ &twl_gpio {
+ otg {
+ gpio-hog;
+ gpios = <6 0>;
+ output-high;
+ line-name = "otg-gpio";
+ };
+ };
