+Maxim MAX77686 multi-function device
+
+MAX77686 is a Mulitifunction device with PMIC, RTC and Charger on chip. It is
+interfaced to host controller using i2c interface. PMIC and Charger
submodules
+are addressed using same i2c slave address where as RTC submodule uses
+different slave address,presently for which we are statically creating i2c
+client while probing.This document describes the binding for mfd device and
+PMIC submodule.
+
+Required properties:
+- compatible : Must be maxim,max77686;
+- reg : Specifiec the i2c slave address of PMIC block.
+- interrupts : This i2c device has an IRQ line connected to the main SoC.
+- interrupt-parent : The parent interrupt controller.
