Subject: [RESEND PATCH v6 01/11] dt-bindings: mfd: add DT bindings for max77650
From: Bartosz Golaszewski <bgolaszewski@...libre.com>
Add a DT binding document for max77650 ultra-low power PMIC. This
describes the core mfd device and the GPIO module.

+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";
+ };
