+	       ----------------------------
+		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.

+Linear Technology LTC3589, LTC3589-1, and LTC3589-2 8-output regulators
+
+Required properties:
+- compatible: "lltc,ltc3589", "lltc,ltc3589-1" or "lltc,ltc3589-2"
+- reg: I2C slave address
+
+Required child node:
+- regulators: Contains eight regulator child nodes sw1, sw2, sw3, bb-out,
+  ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
+  documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The
+nodes for sw1, sw2, sw3, bb-out, ldo1, and ldo2 additionally need to specify
+the resistor values of their external feedback voltage dividers:
+
+Required properties (not on ldo3, ldo4):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+  values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, and ldo2 can regulate the feedback reference from
+0.3625 V to 0.75 V in 12.5 mV steps. The output voltage thus ranges between
+0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1
+have a fixed 0.8 V reference and thus output 0.8 * (1 + R1/R2) V. The ldo3
+regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4
+regulator can output between 1.8 V and 3.3 V on LTC3589 and between 1.2 V
+and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not
+be disabled and thus should have the regulator-always-on property set.

+Linear Technology LTC3676 8-output regulators
+
+Required properties:
+- compatible: "lltc,ltc3676"
+- reg: I2C slave address
+
+Required child node:
+- regulators: Contains eight regulator child nodes sw1, sw2, sw3, sw4,
+  ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
+  documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The
+nodes for sw1, sw2, sw3, sw4, ldo1, ldo2 and ldo4 additionally need to specify
+the resistor values of their external feedback voltage dividers:
+
+Required properties (not on ldo3):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+  values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, sw4 can regulate the feedback reference from:
+412.5mV to 800mV in 12.5 mV steps. The output voltage thus ranges between
+0.4125 * (1 + R1/R2) V and 0.8 * (1 + R1/R2) V.
+
+Regulators ldo1, ldo2, and ldo4 have a fixed 0.725 V reference and thus output
+0.725 * (1 + R1/R2) V. The ldo3 regulator is fixed to 1.8 V.  The ldo1 standby
+regulator can not be disabled and thus should have the regulator-always-on
+property set.
+
+Example:
+
+	ltc3676: pmic@3c {
+		compatible = "lltc,ltc3676";
+		reg = <0x3c>;
+
+		regulators {
+			sw1_reg: sw1 {

+  This is a part of device tree bindings for Maxim MAX77802 Power Management
+  Integrated Circuit (PMIC).
+
+  The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
+  regulators.
+
+  See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
+  additional information and example.
+
+  Certain regulators support "regulator-initial-mode" and "regulator-mode".
+  The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
+  and their meaning is::
+    1 - Normal regulator voltage output mode.
+    3 - Low Power which reduces the quiescent current down to only 1uA
+
+  The standard "regulator-mode" property can only be used for regulators that
+  support changing their mode to Low Power Mode during suspend. These
+  regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
+  regulator has been enabled for the given suspend state using
+  "regulator-on-in-suspend" and has not been disabled for that state using
+  "regulator-off-in-suspend".

+MCP16502 PMIC
+
+Required properties:
+- compatible: "microchip,mcp16502"
+- reg: I2C slave address
+- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
+	     suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
+	     property is optional;
+- regulators: A node that houses a sub-node for each regulator within
+              the device. Each sub-node is identified using the node's
+              name. The content of each sub-node is defined by the
+              standard binding for regulators; see regulator.txt.
+
+Regulators of MCP16502 PMIC:
+1) VDD_IO	- Buck (1.2 - 3.7 V)
+2) VDD_DDR	- Buck (0.6 - 1.85 V)
+3) VDD_CORE	- Buck (0.6 - 1.85 V)
+4) VDD_OTHER	- BUCK (0.6 - 1.85 V)
+5) LDO1		- LDO  (1.2 - 3.7 V)
+6) LDO2		- LDO  (1.2 - 3.7 V)
+
+Regulator modes:
+2 - FPWM: higher precision, higher consumption
+4 - AutoPFM: lower precision, lower consumption
+
+Each regulator is defined using the standard binding for regulators.

+Mediatek MT6323 Regulator
+
+All voltage regulators are defined as subnodes of the regulators node. A list
+of regulators provided by this controller are defined as subnodes of the

+using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are::

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+  as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+  as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+  as the "CPU domain" voltage regulator.
+
+Example:
+
+	pmic {
+		regulators {
+			core_vdd_reg: core {
+				regulator-name = "vdd_core";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;

+spin devices should use the tps659038 as it's compatible value.
+This is the list of those devices:
+tps659037
+
+Required properties:
+- compatible : Should be from the list
+  ti,twl6035-pmic
+  ti,twl6036-pmic
+  ti,twl6037-pmic
+  ti,tps65913-pmic
+  ti,tps65914-pmic
+  ti,tps65917-pmic
+  ti,tps659038-pmic
+and also the generic series names
+  ti,palmas-pmic
+- interrupts : The interrupt number and the type which can be looked up here:
+	       arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
+- interrupts-name: The names of the individual interrupts.
+
+Optional properties:
+- ti,ldo6-vibrator : ldo6 is in vibrator mode
+
+Optional nodes:
+- regulators : Must contain a sub-node per regulator from the list below.
+	       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 custom properties  are listed below.
+
+	       For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
+	       smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
+	       smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
+
+	       Optional sub-node properties:
+	       ti,warm-reset - maintain voltage during warm reset(boolean)
+	       ti,roof-floor - This takes as optional argument on platform supporting
+	       the rail from desired external control. If there is no argument then
+	       it will be assume that it is controlled by NSLEEP pin.
+	       The valid value for external pins are:
+			ENABLE1 then 1,
+			ENABLE2 then 2 or
+			NSLEEP then 3.
+	       ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
+	       2 - eco, 3 - forced pwm
+	       ti,smps-range - OTP has the wrong range set for the hardware so override
+	       0 - low range, 1 - high range.
+
+- ti,system-power-controller: Telling whether or not this pmic is controlling
+			      the system power.
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+pmic {
+	compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
+	interrupt-parent = <&palmas>;

+description: |
+  Currently supports 2 modes of operation:
+
+  Voltage Table:
+    When in this mode, a voltage table (See below) of predefined voltage <=>
+    duty-cycle values must be provided via DT. Limitations are that the
+    regulator can only operate at the voltages supplied in the table.
+    Intermediary duty-cycle values which would normally allow finer grained
+    voltage selection are ignored and rendered useless.  Although more control
+    is given to the user if the assumptions made in continuous-voltage mode do
+    not reign true.
+
+  Continuous Voltage:
+    This mode uses the regulator's maximum and minimum supplied voltages
+    specified in the regulator-{min,max}-microvolt properties to calculate
+    appropriate duty-cycle values.  This allows for a much more fine grained
+    solution when compared with voltage-table mode above.  This solution does
+    make an assumption that a %50 duty-cycle value will cause the regulator
+    voltage to run at half way between the supplied max_uV and min_uV values.
+
+  If voltage-table is provided, then the device will be used in Voltage Table
+  Mode.  If no voltage-table is provided, then the device will be used in
+  Continuous Voltage Mode.

+description: |
+    rpmh-regulator devices support PMIC regulator management via the Voltage
+    Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators.
+    The APPS processor communicates with these hardware blocks via a
+    Resource State Coordinator (RSC) using command packets.  The VRM allows
+    changing three parameters for a given regulator, enable state, output
+    voltage, and operating mode.  The XOB allows changing only a single
+    parameter for a given regulator, its enable state.  Despite its name,
+    the XOB is capable of controlling the enable state of any PMIC peripheral.
+    It is used for clock buffers, low-voltage switches, and LDO/SMPS regulators
+    which have a fixed voltage and mode.
+
+    =======================
+    Required Node Structure
+    =======================
+
+    RPMh regulators must be described in two levels of device nodes.  The first
+    level describes the PMIC containing the regulators and must reside within an
+    RPMh device node.  The second level describes each regulator within the PMIC
+    which is to be used on the board.  Each of these regulators maps to a single
+    RPMh resource.
+
+    The names used for regulator nodes must match those supported by a given
+    PMIC. Supported regulator node names are
+      For PM6150, smps1 - smps5, ldo1 - ldo19
+      For PM6150L, smps1 - smps8, ldo1 - ldo11, bob
+      For PM6350, smps1 - smps5, ldo1 - ldo22
+      For PM660, smps1 - smps6, ldo1 - ldo3, ldo5 - ldo19
+      For PM660L, smps1 - smps3, smps5, ldo1 - ldo8, bob
+      For PM7325, smps1 - smps8, ldo1 - ldo19
+      For PM8005, smps1 - smps4
+      For PM8009, smps1 - smps2, ldo1 - ldo7

+title: QCOM SMD RPM REGULATOR
+
+description:
+  The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+  Because SMD is used as the communication transport mechanism, the RPM
+  resides as a subnode of the SMD.  As such, the SMD-RPM regulator requires
+  that the SMD and RPM nodes be present.
+
+  Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.yaml for
+  information pertaining to the SMD node.
+
+  Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.yaml
+  for information regarding the RPM node.
+
+  The regulator node houses sub-nodes for each regulator within the device.
+  Each sub-node is identified using the node's name, with valid values listed
+  for each of the pmics below.

+Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
+
+Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
+of these regulators are defined under parent device node.
+Details of regulator properties are defined as child node under
+sub-node "regulators" which is child node of device node.
+
+Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
+for common regulator bindings used by client.
+
+Following are properties of parent node related to regulators.
+
+Optional properties:
+-------------------
+The input supply of regulators are the optional properties on the
+parent device node. The input supply of these regulators are provided
+through following properties:
+in-sd0-supply:		Input supply for SD0, INA-SD0 or INB-SD0 pins.
+in-sd1-supply:		Input supply for SD1.
+in-sd2-supply:		Input supply for SD2.
+in-sd3-supply:		Input supply for SD3.
+in-ldo0-1-supply:	Input supply for LDO0 and LDO1.
+in-ldo2-supply:		Input supply for LDO2.
+in-ldo3-5-supply:	Input supply for LDO3 and LDO5
+in-ldo4-6-supply:	Input supply for LDO4 and LDO6.
+in-ldo7-8-supply:	Input supply for LDO7 and LDO8.
+
+Optional sub nodes for regulators under "regulators" subnode:
+------------------------------------------------------------
+The subnodes name is the name of regulator and it must be one of:
+	sd[0-3], ldo[0-8]
+
+Each sub-node should contain the constraints and initialization
+information for that regulator. The definition for each of these
+nodes is defined using the standard binding for regulators found at
+<Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+There are also additional properties for SD/LDOs. These additional properties
+are required to configure FPS configuration parameters for SDs and LDOs.
+Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
+Power Sequence (FPS).
+Following are additional properties:
+
+- maxim,active-fps-source:		FPS source for the regulators to get
+					enabled/disabled when system is in
+					active state.  Valid values are:
+					- MAX77620_FPS_SRC_0,
+						FPS source is FPS0.
+					- MAX77620_FPS_SRC_1,
+						FPS source is FPS1
+					- MAX77620_FPS_SRC_2 and
+						FPS source is FPS2
+					- MAX77620_FPS_SRC_NONE.
+						Regulator is not controlled
+						by FPS events and it gets
+						enabled/disabled by register
+						access.
+					Absence of this property will leave
+					the FPS configuration register for that
+					regulator to default configuration.
+
+- maxim,active-fps-power-up-slot:	Sequencing event slot number on which
+					the regulator get enabled when
+					master FPS input event set to HIGH.
+					Valid values are 0 to 7.
+					This is applicable if FPS source is
+					selected as FPS0, FPS1 or FPS2.
+			
+- maxim,active-fps-power-down-slot:	Sequencing event slot number on which
+					the regulator get disabled when master
+					FPS input event set to LOW.
+					Valid values are 0 to 7.
+					This is applicable if FPS source is
+					selected as FPS0, FPS1 or FPS2.
+			
+- maxim,suspend-fps-source:		This is same as property
+					"maxim,active-fps-source" but value
+					get configured when system enters in
+					to suspend state.
+
+- maxim,suspend-fps-power-up-slot:	This is same as property
+					"maxim,active-fps-power-up-slot" but
+					this value get configured into FPS
+					configuration register when system
+					enters into suspend.
+					This is applicable if suspend state
+					FPS source is selected as FPS0, FPS1 or
+
+- maxim,suspend-fps-power-down-slot:	This is same as property
+					"maxim,active-fps-power-down-slot" but
+					this value get configured into FPS
+					configuration register when system
+					enters into suspend.
+					This is applicable if suspend state
+					FPS source is selected as FPS0, FPS1 or
+					FPS2.
+- maxim,ramp-rate-setting:		integer, ramp rate(uV/us) setting to be
+					configured to the device.
+					The platform may have different ramp
+					rate than advertised ramp rate if it has
+					design variation from Maxim's
+					recommended. On this case, platform
+					specific ramp rate is used for ramp time
+					calculation and this property is used
+					for device register configurations.
+					The measured ramp rate of platform is
+					provided by the regulator-ramp-delay
+					as described in <devicetree/bindings/
+					regulator/regulator.txt>.
+					Maxim Max77620 supports following ramp
+					delay:
+					  SD: 13.75mV/us, 27.5mV/us, 55mV/us
+					  LDOs: 5mV/us, 100mV/us
+
+Note: If the measured ramp delay is same as advertised ramp delay then it is not
+required to provide the ramp delay with property "maxim,ramp-rate-setting". The
+ramp rate can be provided by the regulator-ramp-delay which will be used for
+ramp time calculation for voltage change as well as for device configuration.

+description: |
+  The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for
+  32-bit and 64-bit MCU and MPU applications. It supports DDR3, DDR3L, DDR4,
+  and LPDDR4 memory power requirements. The internally compensated regulators,
+  built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell
+  battery charger provide a highly integrated, small footprint power solution
+  ideal for System-On-Module (SOM) applications. A spread spectrum feature
+  provides an ease-of-use solution for noise-sensitive audio or RF applications.
+
+  This device exposes two devices via I2C. One for the integrated RTC IP, and
+  one for everything else.

+
+description: |
+  RTQ2208 is a highly integrated power converter that offers functional safety dual
+  multi-configurable synchronous buck converters and two LDOs.
+
+  Bucks support "regulator-allowed-modes" and "regulator-mode". The former defines the permitted
+  switching operation in normal mode; the latter defines the operation in suspend to RAM mode.
+
+  No matter the RTQ2208 is configured to normal or suspend to RAM mode, there are two switching
+  operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
+  conduction mode (FCCM).
+
+  The definition of modes is in the datasheet which is available in below link
+  and their meaning is::
+    0 - Auto mode for power saving, which reducing the switching frequency at light load condition
+    to maintain high frequency.
+    1 - FCCM to meet the strict voltage regulation accuracy, which keeping constant switching frequency.
+
+  Datasheet will be available soon at
+  https://www.richtek.com/assets/Products

+Spreadtrum SC2731 Voltage regulators
+
+The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
+14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
+their own bypass (power-down) control signals. External tantalum or MLCC
+ceramic capacitors are recommended to use with these LDOs.
+
+Required properties:
+ - compatible: should be "sprd,sc27xx-regulator".
+
+List of regulators provided by this controller. It is named according to
+its regulator type, BUCK_<name> and LDO_<name>. The definition for each
+of these nodes is defined using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are:
+BUCK:
+	BUCK_CPU0, BUCK_CPU1, BUCK_RF
+LDO:
+	LDO_CAMA0, LDO_CAMA1, LDO_CAMMOT, LDO_VLDO, LDO_EMMCCORE, LDO_SDCORE,

+Adaptive Body Bias(ABB) SoC internal LDO regulator for Texas Instruments SoCs
+
+Required Properties:
+- compatible: Should be one of:
+  - "ti,abb-v1" for older SoCs like OMAP3
+  - "ti,abb-v2" for newer SoCs like OMAP4, OMAP5
+  - "ti,abb-v3" for a generic definition where setup and control registers are
+     provided (example: DRA7)
+- reg: Address and length of the register set for the device. It contains
+  the information of registers in the same order as described by reg-names
+- reg-names: Should contain the reg names
+  - "base-address"	- contains base address of ABB module (ti,abb-v1,ti,abb-v2)
+  - "control-address"	- contains control register address of ABB module (ti,abb-v3)
+  - "setup-address"	- contains setup register address of ABB module (ti,abb-v3)
+  - "int-address"	- contains address of interrupt register for ABB module
+  (also see Optional properties)
+- #address-cells: should be 0
+- #size-cells: should be 0
+- clocks: should point to the clock node used by ABB module
+- ti,settling-time: Settling time in uSecs from SoC documentation for ABB module
+	to settle down(target time for SR2_WTCNT_VALUE).
+- ti,clock-cycles: SoC specific data about count of system ti,clock-cycles used for
+	computing settling time from SoC Documentation for ABB module(clock
+	cycles for SR2_WTCNT_VALUE).
+- ti,tranxdone-status-mask: Mask to the int-register to write-to-clear mask
+	indicating LDO tranxdone (operation complete).
+- ti,abb_info: An array of 6-tuples u32 items providing information about ABB
+	configuration needed per operational voltage of the device.
+	Each item consists of the following in the same order:
+	volt: voltage in uV - Only used to index ABB information.
+	ABB mode: one of the following:
+		0-bypass
+		1-Forward Body Bias(FBB)
+		3-Reverse Body Bias(RBB)
+	efuse:	(see Optional properties)
+	RBB enable efuse Mask:	(See Optional properties)
+	FBB enable efuse Mask:	(See Optional properties)
+	Vset value efuse Mask:	(See Optional properties)
+
+	NOTE: If more than 1 entry is present, then regulator is setup to change
+	      voltage, allowing for various modes to be selected indexed off
+	      the regulator. Further, ABB LDOs are considered always-on by
+	      default.
+
+Optional Properties:
+- reg-names: In addition to the required properties, the following are optional
+  - "efuse-address"	- Contains efuse base address used to pick up ABB info.
+  - "ldo-address"	- Contains address of ABB LDO override register.
+	"efuse-address" is required for this.
+- ti,ldovbb-vset-mask	- Required if ldo-address is set, mask for LDO override
+	register to provide override vset value.
+- ti,ldovbb-override-mask - Required if ldo-address is set, mask for LDO
+	override register to enable override vset value.
+- ti,abb_opp_sel: Addendum to the description in required properties
+	efuse: Mandatory if 'efuse-address' register is defined. Provides offset
+	       from efuse-address to pick up ABB characteristics. Set to 0 if
+	       'efuse-address' is not defined.
+	RBB enable efuse Mask:	Optional if 'efuse-address' register is defined.
+		'ABB mode' is force set to RBB mode if value at "efuse-address"
+		+ efuse maps to RBB mask. Set to 0 to ignore this.
+	FBB enable efuse Mask:	Optional if 'efuse-address' register is defined.
+		'ABB mode' is force set to FBB mode if value at "efuse-address"
+		+ efuse maps to FBB mask (valid only if RBB mask does not match)
+		Set to 0 to ignore this.
+	Vset value efuse Mask:	Mandatory if ldo-address is set. Picks up from
+		efuse the value to set in 'ti,ldovbb-vset-mask' at ldo-address.

+Bindings for Voltage controlled regulators
+==========================================
+
+Required properties:
+--------------------
+- compatible		  : must be "vctrl-regulator".
+- regulator-min-microvolt : smallest voltage consumers may set
+- regulator-max-microvolt : largest voltage consumers may set
+- ctrl-supply		  : The regulator supplying the control voltage.
+- ctrl-voltage-range	  : an array of two integer values describing the range
+			    (min/max) of the control voltage. The values specify
+			    the control voltage needed to generate the corresponding
+			    regulator-min/max-microvolt output voltage.
+
+Optional properties:
+--------------------
+- ovp-threshold-percent	: overvoltage protection (OVP) threshold of the
+			  regulator in percent. Some regulators have an OVP
+			  circuitry which shuts down the regulator when the
+			  actual output voltage deviates beyond a certain
+			  margin from the expected value for a given control
+			  voltage. On larger voltage decreases this can occur
+			  undesiredly since the output voltage does not adjust
+			  immediately to changes in the control voltage. To
+			  avoid this situation the vctrl driver breaks down
+			  larger voltage decreases into multiple steps, where
+			  each step is within the OVP threshold.
+- min-slew-down-rate	: Describes how slowly the regulator voltage will decay
+			  down in the worst case (lightest expected load).
+			  Specified in uV / us (like main regulator ramp rate).
+			  This value is required when ovp-threshold-percent is
+			  specified.
+
+Example:
+
+	vctrl-reg {
+		compatible = "vctrl-regulator";
+		regulator-name = "vctrl_reg";
+
+		ctrl-supply = <&ctrl_reg>;
+
+		regulator-min-microvolt = <800000>;
+		regulator-max-microvolt = <1500000>;
+
+		ctrl-voltage-range = <200000 500000>;
+
+		min-slew-down-rate = <225>;
