-Analog Devices LT3651 Charger Power Supply bindings: lt3651-charger
-
-Required properties:
-- compatible: Should contain one of the following:
- * "lltc,ltc3651-charger", (DEPRECATED: Use "lltc,lt3651-charger")
- * "lltc,lt3651-charger"
- - lltc,acpr-gpios: Connect to ACPR output. See remark below.
-
-Optional properties:
- - lltc,fault-gpios: Connect to FAULT output. See remark below.
- - lltc,chrg-gpios: Connect to CHRG output. See remark below.
-
-The lt3651 outputs are open-drain type and active low. The driver assumes the
-GPIO reports "active" when the output is asserted, so if the pins have been
-connected directly, the GPIO flags should be set to active low also.
-
-The driver will attempt to aquire interrupts for all GPIOs to detect changes in
-line state. If the system is not capabale of providing interrupts, the driver
-cannot report changes and userspace will need to periodically read the sysfs
-attributes to detect changes.
-
-Example:
-
-	charger: battery-charger {
-		compatible = "lltc,lt3651-charger";
-		lltc,acpr-gpios = <&gpio0 68 GPIO_ACTIVE_LOW>;
-		lltc,fault-gpios = <&gpio0 64 GPIO_ACTIVE_LOW>;
-		lltc,chrg-gpios = <&gpio0 63 GPIO_ACTIVE_LOW>;
-	};
