+Required parent device properties:
+- compatible : contains "stericsson,ab8500";
+- interrupts : contains the IRQ line for the AB8500
+- interrupt-controller : describes the AB8500 as an Interrupt Controller (has its own domain)
+- #interrupt-cells : should be 2, for 2-cell format
+ - The first cell is the AB8500 local IRQ number
+ - The second cell is used to specify optional parameters
+ - bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+
+Optional parent device properties:
+- reg : contains the PRCMU mailbox address for the AB8500 i2c port
+
+The AB8500 consists of a large and varied group of sub-devices:

+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 whereas RTC submodule uses
+different i2c 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 : Specifies 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.
+
+Optional node:
+- voltage-regulators : The regulators of max77686 have to be instantiated
+ under subnode named "voltage-regulators" using the following format.
+
+ regulator_name {
+ regulator-compatible = LDOn/BUCKn
+ standard regulator constraints....
+ };
+ refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+ The regulator-compatible property of regulator should initialized with string
+to get matched with their hardware counterparts as follow:
+
+ -LDOn : for LDOs, where n can lie in range 1 to 26.
+ example: LDO1, LDO2, LDO26.
+ -BUCKn : for BUCKs, where n can lie in range 1 to 9.
+ example: BUCK1, BUCK5, BUCK9.
+
+Example:
+
+ max77686@09 {
+ compatible = "maxim,max77686";
+ interrupt-parent = <&wakeup_eint>;
+ interrupts = <26 0>;
+ reg = <0x09>;

+ regulator-always-on;
