+description: |
+ 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

+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>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-core-regulator;
+ };
+
+ rtc_vdd_reg: rtc {
+ regulator-name = "vdd_rtc";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-rtc-regulator;
+ };
+
+ cpu_vdd_reg: cpu {
+ regulator-name = "vdd_cpu";
+ regulator-min-microvolt = <750000>;
+ regulator-max-microvolt = <1125000>;
+ regulator-coupled-with = <&core_vdd_reg &rtc_vdd_reg>;
+ regulator-coupled-max-spread = <550000 550000>;
+

+ };
+ };

+* palmas regulator IP block devicetree bindings
+
+The tps659038 for the AM57x class have OTP spins that
+have different part numbers but the same functionality. There
+is not a need to add the OTP spins to the palmas driver. The
+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>;

+ regulator-name = "smps12";
+ regulator-min-microvolt = < 600000>;
+ regulator-max-microvolt = <1500000>;
+ regulator-always-on;
+ regulator-boot-on;
+ ti,warm-reset;
+ ti,roof-floor = <1>; /* ENABLE1 control */
+ ti,mode-sleep = <0>;
+ ti,smps-range = <1>;
+ };

+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

+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

+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.

+ and will not provide any enable/disable APIs.
+- ti,overcurrent-wait: This is applicable to FET registers, which have a
+ poorly defined "overcurrent wait" field. If this property is present it

+ -For regulator outp, the sub node name should be "outp".
+ -For regulator outn, the sub node name should be "outn".

+-enable-gpios:(active high, output) Regulators are controlled by the input pins.

+-active-discharge-gpios: (active high, output) Some configurations use delay mechanisms
+ on the enable pin, to keep the regulator enabled for some time after

+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>;
+ ovp-threshold-percent = <16>;
+ };

+Versatile Express voltage regulators
+------------------------------------
+
+Requires node properties:
+- "compatible" value: "arm,vexpress-volt"
+- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
+ (see Documentation/devicetree/bindings/arm/vexpress-config.yaml
+ for more details)
+
+Required regulator properties:
+- "regulator-name"
+- "regulator-always-on"
+
+Optional regulator properties:
+- "regulator-min-microvolt"
+- "regulator-max-microvolt"
+
+See Documentation/devicetree/bindings/regulator/regulator.txt
+for more details about the regulator properties.
+
+When no "regulator-[min|max]-microvolt" properties are defined,
+the device is treated as fixed (or rather "read-only") regulator.
+
+Example:
+ volt@0 {
+ compatible = "arm,vexpress-volt";
+ arm,vexpress-sysreg,func = <2 0>;
+ regulator-name = "Cores";
+ regulator-min-microvolt = <800000>;
+ regulator-max-microvolt = <1050000>;
+ regulator-always-on;
