+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>;

+* System Controller Registers R/W driver
+
+System controller node represents a register region containing a set
+of miscellaneous registers. The registers are not cohesive enough to
+represent as any specific type of device. The typical use-case is for
+some other node's driver, or platform-specific code, to acquire a
+reference to the syscon node (e.g. by phandle, node path, or search
+using a specific compatible value), interrogate the node (or associated
+OS driver) to determine the location of the registers, and access the
+registers directly.

+Required properties:
+- compatible: Should contain "syscon".
+- reg: the register region can be accessed from syscon

+Texas Instruments TWL family (twl4030) audio module
+
+The audio module inside the TWL family consist of an audio codec and a vibra
+driver.
+
+Required properties:
+- compatible : must be "ti,twl4030-audio"
+
+Optional properties, nodes:
+
+Audio functionality:
+- codec { }: Need to be present if the audio functionality is used. Within this
+	     section the following options can be used:
+- ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts
+		    from the start of the recorded sample (in ms)
+-ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise
+-ti,hs_extmute: Use external mute for HS pop reduction
+-ti,hs_extmute_gpio: Use external GPIO to control the external mute
+-ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the
+		      valid values.
+
+Vibra functionality
+- ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if
+		   missing or it is 0, the vibra functionality is disabled.
+
+Example:
+&i2c1 {
+	clock-frequency = <2600000>;
+
+	twl: twl@48 {
+		reg = <0x48>;
+		interrupts = <7>; /* SYS_NIRQ cascaded to intc */
+		interrupt-parent = <&intc>;
+
+		twl_audio: audio {
+			compatible = "ti,twl4030-audio";
+
+			ti,enable-vibra = <1>;
+
+			codec {
+				ti,ramp_delay_value = <3>;
+			};

+Texas Instruments TWL6040 family
+
+The TWL6040s are 8-channel high quality low-power audio codecs providing audio,
+vibra and GPO functionality on OMAP4+ platforms.
+They are connected ot the host processor via i2c for commands, McPDM for audio
+data and commands.
+
+Required properties:
+- compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041
+- reg: must be 0x4b for i2c address
+- interrupts: twl6040 has one interrupt line connecteded to the main SoC
+- interrupt-parent: The parent interrupt controller
+- gpio-controller:
+- #gpio-cells = <1>: twl6040 provides GPO lines.
+- twl6040,audpwron-gpio: Power on GPIO line for the twl6040
+
+- vio-supply: Regulator for the twl6040 VIO supply
+- v2v1-supply: Regulator for the twl6040 V2V1 supply
+
+Optional properties, nodes:
+- enable-active-high: To power on the twl6040 during boot.
+
+Vibra functionality
+Required properties:
+- vddvibl-supply: Regulator for the left vibra motor
+- vddvibr-supply: Regulator for the right vibra motor
+- vibra { }: Configuration section for vibra parameters containing the following
+	     properties:
+- ti,vibldrv-res: Resistance parameter for left driver
+- ti,vibrdrv-res: Resistance parameter for right driver
+- ti,viblmotor-res: Resistance parameter for left motor
+- ti,viblmotor-res: Resistance parameter for right motor
+
+Optional properties within vibra { } section:
+- vddvibl_uV: If the vddvibl default voltage need to be changed
+- vddvibr_uV: If the vddvibr default voltage need to be changed
+
+Example:
+&i2c1 {
+	twl6040: twl@4b {
+		compatible = "ti,twl6040";
+
+		interrupts = <0 119 4>;
