13 Devices work at voltage-current-frequency combinations and some implementations
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
63 opp-microvolt:
67 A single regulator's voltage is specified with an array of size one or three.
68 Single entry is for target voltage and three entries are for <target min max>
85 opp-microamp:
92 Should only be set if opp-microvolt or opp-microvolt-<name> is set for
106 opp-microwatt:
108 The power for the OPP in micro-Watts.
121 opp-level:
123 A value representing the performance level of the device.
126 opp-peak-kBps:
129 32-bit big-endian integers. Each element of the array represents the
135 opp-avg-kBps:
138 of 32-bit big-endian integers. Each element of the array represents the
141 meaningful in OPP tables where opp-peak-kBps is present.
145 clock-latency-ns:
150 turbo-mode:
158 opp-suspend:
161 the table have this, the OPP with highest opp-hz will be used.
164 opp-supported-hw:
171 a sub-group of hardware versions supported by the OPP. i.e. <sub-group
172 A>, <sub-group B>, etc. The OPP will be enabled if _any_ of these
173 sub-groups match the hardware's version.
175 Each sub-group is a platform defined array representing the hierarchy
177 three hierarchical levels of version (X.Y.Z), this field shall look
180 opp-supported-hw = <X1 Y1 Z1>, <X2 Y2 Z2>, <X3 Y3 Z3>.
182 Each level (eg. X1) in version hierarchy is represented by a 32 bit
184 level. Logical AND (&) operation is performed for each level with the
185 hardware's level version and a non-zero output for _all_ the levels in
186 a sub-group means the OPP is supported by hardware. A value of
187 0xFFFFFFFF for each level in the sub-group will enable the OPP for all

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

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

227 Named opp-microamp property. Similar to opp-microvolt-<name> property,
