+MediaTek MT6360 PMIC Driver
+
+MT6360 is a multifunction device with the following sub modules:
+It is interfaced to host controller using I2C interface.
+This document describes the binding for PMIC device and its sub module.
+
+- ADC
+- Battery Charger/OTG boost
+- Flash LED/RGB LED/moonlight LED
+- 2-channel Buck and 6-channel LDO
+- USB_PD
+
+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 and 6-channel LDO
+	Required properties:
+		- compatible: "mediatek,mt6360-regulator"
+- USB_PD
+	Required properties:
+		- compatible: "mediatek,mt6360-tcpc"
+
