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-parent = <&gpio2>;
|
||||
#interrupt-cells = <2>;
|
||||
interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
|
||||
|
||||
gpio-controller;
|
||||
#gpio-cells = <2>;
|
||||
gpio-line-names = "max77650-charger";
|
||||
};

MAX77650 is an ultra-low power PMIC providing battery charging and power
|
||||
supply for low-power IoT and wearable applications.
|

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,
|
