+MediaTek MT6360 Multifunction Device Driver
+
+MT6360 is a multifunction device with the following sub modules:
+- ADC
+- Battery Charger/OTG boost
+- Flash LED/RGB LED/moonlight LED
+- 2-channel Buck
+- 6-channel LDO
+- USB_PD
+
+It is interfaced to host controller using I2C interface.
+This document describes the binding for MFD device and its sub module.
+
+Required properties:
+- compatible:	Must be "mediatek,mt6360_pmu"
+- reg:			Specifies the I2C slave address of PMIC block, Must be <0x34>
+- interrupts:	I2C device IRQ line connected to the main SoC.
+
+Optional subnodes:
+- ADC
+	Required properties:
+		- compatible: "mediatek,mt6360_adc"
+- battery charger/OTG boost
+	Required properties:
+		- compatible: "mediatek,mt6360_chg"
+- Flash LED/RGB LED/moonlight LED
+	Required properties:
+		- compatible: "mediatek,mt6360_led"
+- 2-channel Buck
+	Required properties:
+		- compatible: "mediatek,mt6360_pmic"
+- 6-channel LDO
+	Required properties:
+		- compatible: "mediatek,mt6360_ldo"
+- USB_PD
+	Required properties:
+		- compatible: "mediatek,mt6360_tcpc"
+
+Example:
+
+	#include <dt-bindings/usb/pd.h>
+
+	pmu: mt6360_pmu@34 {
+		status = "ok";
+		compatible = "mediatek,mt6360_pmu";
+		reg = <0x34>;
+		wakeup-source;
+		interrupts-extended = <&gpio26 0 IRQ_TYPE_LEVEL_LOW>;
+		interrupt-names = "IRQB";
+		interrupt-controller;
+		#interrupt-cells = <2>;
+	};
