-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>;
