25     pattern: '^opp-table(-[a-z0-9]+)?$'
27   opp-shared:
36   '^opp(-?[0-9]+)*$':
39       One or more OPP nodes describing voltage-current-frequency combinations.
42       present only to indicate dependency between devices using the opp-shared
46       opp-hz:
48           Frequency in Hz, expressed as a 64-bit big-endian integer. This is a
61       opp-microvolt:
83       opp-microamp:
86           system specific parameters (such as transients, process, aging,
90           Should only be set if opp-microvolt or opp-microvolt-<name> is set for
104       opp-microwatt:
106           The power for the OPP in micro-Watts.
119       opp-level:
124       opp-peak-kBps:
127           32-bit big-endian integers. Each element of the array represents the
133       opp-avg-kBps:
136           of 32-bit big-endian integers. Each element of the array represents the
139           meaningful in OPP tables where opp-peak-kBps is present.

148       turbo-mode:
156       opp-suspend:
159           the table have this, the OPP with highest opp-hz will be used.
162       opp-supported-hw:
166           version of the hardware (already known to the operating system).
169           a sub-group of hardware versions supported by the OPP. i.e. <sub-group
170           A>, <sub-group B>, etc. The OPP will be enabled if _any_ of these
171           sub-groups match the hardware's version.
173           Each sub-group is a platform defined array representing the hierarchy
178           opp-supported-hw = <X1 Y1 Z1>, <X2 Y2 Z2>, <X3 Y3 Z3>.
183           hardware's level version and a non-zero output for _all_ the levels in
184           a sub-group means the OPP is supported by hardware. A value of
185           0xFFFFFFFF for each level in the sub-group will enable the OPP for all

198           OPP nodes in the same OPP table. This specifies the minimum required

207       '^opp-microvolt-':
209           Named opp-microvolt property. This is exactly similar to the above
210           opp-microvolt property, but allows multiple voltage ranges to be
212           and matching opp-microvolt-<name> property will be enabled for all

215           opp-microvolt property shall be used, if present.
