-MAX77650 ultra low-power PMIC from Maxim Integrated.
-
-Required properties:
--------------------
-- compatible: Must be "maxim,max77650"
-- reg: I2C device address.
-- interrupts: The interrupt on the parent the controller is
- connected to.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Must be <2>.
-
-- gpio-controller: Marks the device node as a gpio controller.
-- #gpio-cells: Must be <2>. The first cell is the pin number and
- the second cell is used to specify the gpio active
- state.
-
-Optional properties:
---------------------
-gpio-line-names: Single string containing the name of the GPIO line.
-
-The GPIO-controller module is represented as part of the top-level PMIC
-node. The device exposes a single GPIO line.
-
-For device-tree bindings of other sub-modules (regulator, power supply,
-LEDs and onkey) refer to the binding documents under the respective
-sub-system directories.
-
-For more details on GPIO bindings, please refer to the generic GPIO DT
-binding document <devicetree/bindings/gpio/gpio.txt>.
-
-Example:
---------
-
- pmic@48 {
- compatible = "maxim,max77650";
- reg = <0x48>;
-
- interrupt-controller;
- interrupt-parent = <&gpio2>;
- #interrupt-cells = <2>;
- interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
-
- gpio-controller;
- #gpio-cells = <2>;
- gpio-line-names = "max77650-charger";
- };
