-TI BQ24190 Li-Ion Battery Charger
-
-Required properties:
-- compatible: contains one of the following:
-    * "ti,bq24190"
-    * "ti,bq24192"
-    * "ti,bq24192i"
-    * "ti,bq24196"
-- 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.
-
-child nodes:
-- usb-otg-vbus:
-  Usage: optional
-  Description: Regulator that is used to control the VBUS voltage direction for
-               either USB host mode or for charging on the OTG port.
-
-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>;

-		usb_otg_vbus: usb-otg-vbus { };
