+description: |
+ For some SoCs, the CPU frequency subset and voltage value of each
+ OPP varies based on the silicon variant in use. Allwinner Process
+ Voltage Scaling Tables defines the voltage and frequency value based
+ on the speedbin blown in the efuse combination. The
+ sun50i-cpufreq-nvmem driver reads the efuse value from the SoC to
+ provide the OPP framework with required information.

+Generic OPP (Operating Performance Points) Bindings
+----------------------------------------------------
+
+Devices work at voltage-current-frequency combinations and some implementations
+have the liberty of choosing these. These combinations are called Operating
+Performance Points aka OPPs. This document defines bindings for these OPPs
+applicable across wide range of devices. For illustration purpose, this document
+uses CPU as a device.
+
+This document contain multiple versions of OPP binding and only one of them
+should be used per device.
+
+Binding 1: operating-points
+============================
+
+This binding only supports voltage-frequency pairs.
+
+Properties:
+- operating-points: An array of 2-tuples items, and each item consists
+ of frequency and voltage like <freq-kHz vol-uV>.
+ freq: clock frequency in kHz
+ vol: voltage in microvolt
+
+Examples:
+
+cpu@0 {
+ compatible = "arm,cortex-a9";
+ reg = <0>;
+ next-level-cache = <&L2>;
+ operating-points = <
+ /* kHz uV */
+ 792000 1100000
+ 396000 950000
+ 198000 850000
+ >;
+};
+
+
+Binding 2: operating-points-v2
+============================
+
+* Property: operating-points-v2
+
+Devices supporting OPPs must set their "operating-points-v2" property with
+phandle to a OPP table in their DT node. The OPP core will use this phandle to
+find the operating points for the device.
+
+This can contain more than one phandle for power domain providers that provide
+multiple power domains. That is, one phandle for each power domain. If only one
+phandle is available, then the same OPP table will be used for all power domains
+provided by the power domain provider.
+
+If required, this can be extended for SoC vendor specific bindings. Such bindings
+should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
+and should have a compatible description like: "operating-points-v2-<vendor>".
+
+* OPP Table Node
+
+This describes the OPPs belonging to a device. This node can have following
+properties:
+
+Required properties:
+- compatible: Allow OPPs to express their compatibility. It should be:
+ "operating-points-v2".
+
+- OPP nodes: One or more OPP nodes describing voltage-current-frequency
+ combinations. Their name isn't significant but their phandle can be used to
+ reference an OPP.
+
+Optional properties:
+- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
+ switch their DVFS state together, i.e. they share clock/voltage/current lines.
+ Missing property means devices have independent clock/voltage/current lines,
+ but they share OPP tables.
+
+- status: Marks the OPP table enabled/disabled.
+
+
+* OPP Node
+
+This defines voltage-current-frequency combinations along with other related
+properties.
+
+Required properties:
+- opp-hz: Frequency in Hz, expressed as a 64-bit big-endian integer. This is a
+ required property for all device nodes, unless another "required" property to
+ uniquely identify the OPP nodes exists. Devices like power domains must have
+ another (implementation dependent) property.
+
+- opp-peak-kBps: Peak bandwidth in kilobytes per second, expressed as an array
+ of 32-bit big-endian integers. Each element of the array represents the
+ peak bandwidth value of each interconnect path. The number of elements should
+ match the number of interconnect paths.
+
+Optional properties:
+- opp-microvolt: voltage in micro Volts.
+
+ A single regulator's voltage is specified with an array of size one or three.
+ Single entry is for target voltage and three entries are for <target min max>
+ voltages.
+
+ Entries for multiple regulators shall be provided in the same field separated
+ by angular brackets <>. The OPP binding doesn't provide any provisions to
+ relate the values to their power supplies or the order in which the supplies
+ need to be configured and that is left for the implementation specific
+ binding.
+
+ Entries for all regulators shall be of the same size, i.e. either all use a
+ single value or triplets.
+
+- opp-microvolt-<name>: Named opp-microvolt property. This is exactly similar to
+ the above opp-microvolt property, but allows multiple voltage ranges to be
+ provided for the same OPP. At runtime, the platform can pick a <name> and
+ matching opp-microvolt-<name> property will be enabled for all OPPs. If the
+ platform doesn't pick a specific <name> or the <name> doesn't match with any
+ opp-microvolt-<name> properties, then opp-microvolt property shall be used, if
+ present.
+
+- opp-microamp: The maximum current drawn by the device in microamperes
+ considering system specific parameters (such as transients, process, aging,
+ maximum operating temperature range etc.) as necessary. This may be used to
+ set the most efficient regulator operating mode.
+
+ Should only be set if opp-microvolt is set for the OPP.
+
+ Entries for multiple regulators shall be provided in the same field separated
+ by angular brackets <>. If current values aren't required for a regulator,
+ then it shall be filled with 0. If current values aren't required for any of
+ the regulators, then this field is not required. The OPP binding doesn't
+ provide any provisions to relate the values to their power supplies or the
+ order in which the supplies need to be configured and that is left for the
+ implementation specific binding.
+
+- opp-microamp-<name>: Named opp-microamp property. Similar to
+ opp-microvolt-<name> property, but for microamp instead.
+
+- opp-level: A value representing the performance level of the device,
+ expressed as a 32-bit integer.
+
+- opp-avg-kBps: Average bandwidth in kilobytes per second, expressed as an array
+ of 32-bit big-endian integers. Each element of the array represents the
+ average bandwidth value of each interconnect path. The number of elements
+ should match the number of interconnect paths. This property is only
+ meaningful in OPP tables where opp-peak-kBps is present.
+
+- clock-latency-ns: Specifies the maximum possible transition latency (in
+ nanoseconds) for switching to this OPP from any other OPP.
+
+- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
+ available on some platforms, where the device can run over its operating
+ frequency for a short duration of time limited by the device's power, current
+ and thermal limits.
+
+- opp-suspend: Marks the OPP to be used during device suspend. If multiple OPPs
+ in the table have this, the OPP with highest opp-hz will be used.
+
+- opp-supported-hw: This property allows a platform to enable only a subset of
+ the OPPs from the larger set present in the OPP table, based on the current
+ version of the hardware (already known to the operating system).
+
+ Each block present in the array of blocks in this property, represents a
+ sub-group of hardware versions supported by the OPP. i.e. <sub-group A>,
+ <sub-group B>, etc. The OPP will be enabled if _any_ of these sub-groups match
+ the hardware's version.
+
+ Each sub-group is a platform defined array representing the hierarchy of
+ hardware versions supported by the platform. For a platform with three
+ hierarchical levels of version (X.Y.Z), this field shall look like
+
+ opp-supported-hw = <X1 Y1 Z1>, <X2 Y2 Z2>, <X3 Y3 Z3>.
+
+ Each level (eg. X1) in version hierarchy is represented by a 32 bit value, one
+ bit per version and so there can be maximum 32 versions per level. Logical AND
+ (&) operation is performed for each level with the hardware's level version
+ and a non-zero output for _all_ the levels in a sub-group means the OPP is
+ supported by hardware. A value of 0xFFFFFFFF for each level in the sub-group
+ will enable the OPP for all versions for the hardware.
+
+- status: Marks the node enabled/disabled.
+
+- required-opps: This contains phandle to an OPP node in another device's OPP
+ table. It may contain an array of phandles, where each phandle points to an
+ OPP of a different device. It should not contain multiple phandles to the OPP
+ nodes in the same OPP table. This specifies the minimum required OPP of the
+ device(s), whose OPP's phandle is present in this property, for the
+ functioning of the current device at the current OPP (where this property is
+ present).

+Qualcomm Technologies, Inc. NVMEM CPUFreq and OPP bindings
+===================================
+
+In Certain Qualcomm Technologies, Inc. SoCs like apq8096 and msm8996,
+the CPU frequencies subset and voltage value of each OPP varies based on
+the silicon variant in use.
+Qualcomm Technologies, Inc. Process Voltage Scaling Tables
+defines the voltage and frequency value based on the msm-id in SMEM
+and speedbin blown in the efuse combination.
+The qcom-cpufreq-nvmem driver reads the msm-id and efuse value from the SoC
+to provide the OPP framework with required information (existing HW bitmap).
+This is used to determine the voltage and frequency value for each OPP of
+operating-points-v2 table when it is parsed by the OPP framework.
+
+Required properties:
+--------------------
+In 'cpu' nodes:
+- operating-points-v2: Phandle to the operating-points-v2 table to use.
+
+In 'operating-points-v2' table:
+- compatible: Should be
+ - 'operating-points-v2-kryo-cpu' for apq8096, msm8996, msm8974,
+ apq8064, ipq8064, msm8960 and ipq8074.
+
+Optional properties:
+--------------------
+In 'cpu' nodes:
+- power-domains: A phandle pointing to the PM domain specifier which provides
+ the performance states available for active state management.
+ Please refer to the power-domains bindings
+ Documentation/devicetree/bindings/power/power_domain.txt
+ and also examples below.
+- power-domain-names: Should be
+ - 'cpr' for qcs404.
+
+In 'operating-points-v2' table:
+- nvmem-cells: A phandle pointing to a nvmem-cells node representing the
+ efuse registers that has information about the
+ speedbin that is used to select the right frequency/voltage
+ value pair.
+ Please refer the for nvmem-cells
+ bindings Documentation/devicetree/bindings/nvmem/nvmem.txt
+ and also examples below.
+
+In every OPP node:
+- opp-supported-hw: A single 32 bit bitmap value, representing compatible HW.
+ Bitmap:
+ 0: MSM8996 V3, speedbin 0
+ 1: MSM8996 V3, speedbin 1
+ 2: MSM8996 V3, speedbin 2
+ 3: unused
+ 4: MSM8996 SG, speedbin 0
+ 5: MSM8996 SG, speedbin 1
+ 6: MSM8996 SG, speedbin 2
+ 7-31: unused

+Qualcomm OPP bindings to describe OPP nodes
+
+The bindings are based on top of the operating-points-v2 bindings
+described in Documentation/devicetree/bindings/opp/opp.txt
+Additional properties are described below.
+
+* OPP Table Node
+
+Required properties:
+- compatible: Allow OPPs to express their compatibility. It should be:
+ "operating-points-v2-qcom-level"
+
+* OPP Node
+
+Required properties:
+- qcom,opp-fuse-level: A positive value representing the fuse corner/level
+ associated with this OPP node. Sometimes several corners/levels shares
+ a certain fuse corner/level. A fuse corner/level contains e.g. ref uV,
+ min uV, and max uV.

+Texas Instruments OMAP compatible OPP supply description
+
+OMAP5, DRA7, and AM57 family of SoCs have Class0 AVS eFuse registers which
+contain data that can be used to adjust voltages programmed for some of their
+supplies for more efficient operation. This binding provides the information
+needed to read these values and use them to program the main regulator during
+an OPP transitions.
+
+Also, some supplies may have an associated vbb-supply which is an Adaptive Body
+Bias regulator which much be transitioned in a specific sequence with regards
+to the vdd-supply and clk when making an OPP transition. By supplying two
+regulators to the device that will undergo OPP transitions we can make use
+of the multi regulator binding that is part of the OPP core described here [1]
+to describe both regulators needed by the platform.
+
+[1] Documentation/devicetree/bindings/opp/opp.txt
+
+Required Properties for Device Node:
+- vdd-supply: phandle to regulator controlling VDD supply
+- vbb-supply: phandle to regulator controlling Body Bias supply
+ (Usually Adaptive Body Bias regulator)
+
+Required Properties for opp-supply node:
+- compatible: Should be one of:
+ "ti,omap-opp-supply" - basic OPP supply controlling VDD and VBB
+ "ti,omap5-opp-supply" - OMAP5+ optimized voltages in efuse(class0)VDD
+ along with VBB
+ "ti,omap5-core-opp-supply" - OMAP5+ optimized voltages in efuse(class0) VDD
+ but no VBB.
+- reg: Address and length of the efuse register set for the device (mandatory
+ only for "ti,omap5-opp-supply")
+- ti,efuse-settings: An array of u32 tuple items providing information about
+ optimized efuse configuration. Each item consists of the following:
+ volt: voltage in uV - reference voltage (OPP voltage)
+ efuse_offseet: efuse offset from reg where the optimized voltage is stored.
+- ti,absolute-max-voltage-uv: absolute maximum voltage for the OPP supply.
+
+Example:
+
+/* Device Node (CPU) */

+ cpu0: cpu@0 {
+ device_type = "cpu";
