+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"
