+* ams AS3722 Power management IC.
+
+Required properties:
+-------------------
+- compatible: Must be "ams,as3722".
+- reg: I2C device address.
+- interrupt-controller: AS3722 has internal interrupt controller which takes the
+ interrupt request from internal sub-blocks like RTC, regulators, GPIOs as well
+ as external input.
+- #interrupt-cells: Should be set to 2 for IRQ number and flags.
+ The first cell is the IRQ number. IRQ numbers for different interrupt source
+ of AS3722 are defined at dt-bindings/mfd/as3722.h
+ The second cell is the flags, encoded as the trigger masks from binding document
+ interrupts.txt, using dt-bindings/irq.
+
+Optional submodule and their properties:
+=======================================
+
+Pinmux and GPIO:
+===============
+Device has 8 GPIO pins which can be configured as GPIO as well as the special IO
+functions.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Following are properties which is needed if GPIO and pinmux functionality
+is required:
+ Required properties:
+ -------------------
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Number of GPIO cells. Refer to binding document
+ gpio/gpio.txt
+
+ Optional properties:
+ --------------------
+ Following properties are require if pin control setting is required
+ at boot.
+ - pinctrl-names: A pinctrl state named "default" be defined, using the
+ bindings in pinctrl/pinctrl-binding.txt.
+ - pinctrl[0...n]: Properties to contain the phandle that refer to
+ different nodes of pin control settings. These nodes represents
+ the pin control setting of state 0 to state n. Each of these
+ nodes contains different subnodes to represents some desired
+ configuration for a list of pins. This configuration can
+ include the mux function to select on those pin(s), and
+ various pin configuration parameters, such as pull-up,
+ open drain.
+
+ Each subnode have following properties:
+ Required properties:
+ - pins: List of pins. Valid values of pins properties are:
+ gpio0, gpio1, gpio2, gpio3, gpio4, gpio5,
+ gpio6, gpio7
+
+ Optional properties:
+ function, bias-disable, bias-pull-up, bias-pull-down,
+ bias-high-impedance, drive-open-drain.
+
+ Valid values for function properties are:
+ gpio, interrupt-out, gpio-in-interrupt,
+ vsup-vbat-low-undebounce-out,
+ vsup-vbat-low-debounce-out,
+ voltage-in-standby, oc-pg-sd0, oc-pg-sd6,
+ powergood-out, pwm-in, pwm-out, clk32k-out,
+ watchdog-in, soft-reset-in
+
+Regulators:
+===========
+Device has multiple DCDC and LDOs. The node "regulators" is require if regulator
+functionality is needed.
+
+Following are properties of regulator subnode.
+
+ Optional properties:
+ -------------------
+ The input supply of regulators are the optional properties on the
+ regulator node. The input supply of these regulators are provided
+ through following properties:
+ vsup-sd2-supply: Input supply for SD2.
+ vsup-sd3-supply: Input supply for SD3.
+ vsup-sd4-supply: Input supply for SD4.
+ vsup-sd5-supply: Input supply for SD5.
+ vin-ldo0-supply: Input supply for LDO0.
+ vin-ldo1-6-supply: Input supply for LDO1 and LDO6.
+ vin-ldo2-5-7-supply: Input supply for LDO2, LDO5 and LDO7.
+ vin-ldo3-4-supply: Input supply for LDO3 and LDO4.
+ vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
+ vin-ldo11-supply: Input supply for LDO11.
+
+ Optional sub nodes for regulators:
+ ---------------------------------
+ The subnodes name is the name of regulator and it must be one of:
+ sd[0-6], ldo[0-7], ldo[9-11]
+
+ Each sub-node should contain the constraints and initialization
+ information for that regulator. See regulator.txt for a description
+ of standard properties for these sub-nodes.
+ Additional optional custom properties are listed below.
+ ams,ext-control: External control of the rail. The option of
+ this properties will tell which external input is
+ controlling this rail. Valid values are 0, 1, 2 ad 3.
+ 0: There is no external control of this rail.
+ 1: Rail is controlled by ENABLE1 input pin.
+ 2: Rail is controlled by ENABLE2 input pin.
+ 3: Rail is controlled by ENABLE3 input pin.
+ Missing this property on DT will be assume as no
+ external control. The external control pin macros
+ are defined @dt-bindings/mfd/as3722.h
+
+ ams,enable-tracking: Enable tracking with SD1, only supported
+ by LDO3.
+
+Example:
+--------
+#include <dt-bindings/mfd/as3722.h>
+...
