+      turbo-mode:
+        description:
+          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,

+        type: boolean
+
+      opp-supported-hw:
+        description: |
+          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.

-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. These are mandatory except for the case where the OPP table
-  is present only to indicate dependency between devices using the opp-shared
-  property.
-
-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).
