5 and get frequency count from pvtm, then supplies the OPP framework
6 with 'prop' information which is used to determine opp-microvolt-<name>
8 on operating-points-v2, but the driver can also create the "cpufreq-dt"
9 platform_device to compatibility with operating-points.
14 In 'operating-points-v2' table:
15 - rockchip,leakage-voltage-sel: The property is an array of 3-tuples items, and
17                        <min-leakage max-leakage volt-selector>.
18                        min-leakage: minimum leakage in mA, ranges from 1 to 254.
19                        max-leakage: maximum leakage in mA, ranges from 1 to 254.
20                        voltage-selector: a sequence number which is used to math
21                        opp-microvolt-L<number> roperty in OPP node.
23 - rockchip,pvtm-voltage-sel: The property is an array of 3-tuples items, and
25                        <min-pvtm max-pvtm volt-selector>.
26                        min-pvtm: minimum frequency count in KHz.
27                        max-pvtm: maximum frequency count in KHz.
28                        voltage-selector: a sequence number which is used to math
29                        opp-microvolt-L<number> roperty in OPP node.
30 - rockchip,pvtm-freq: Clock frequency in KHz, which is used to set the cpu clock
31                        frequency before get frequency count of pvtm.
32 - rockchip,pvtm-volt: Voltage in uV, which is used to set the cpu voltage before
33                        get frequency count of pvtm.
34 - rockchip,pvtm-ch: An array of two integers containing pvtm channel and clock
36 - rockchip,pvtm-sample-time: The number of milliseconds to wait for pvtm to
38 - rockchip,pvtm-number: An integer indicating the number of sampling points.
39 - rockchip,pvtm-error: An integer indicating the error between the sample
41 - rockchip,pvtm-ref-temp: The SoC internal temperature in degree centigrade, the
42                        min-pvtm and max-pvtm in 'leakage-voltage-sel' are
44 - rockchip,pvtm-temp-prop: An array of two integers containing proportional
50 - rockchip,pvtm-thermal-zone: A thermal zone node containing thermal sensor,
52 - rockchip,thermal-zone: A thermal zone node containing thermal sensor,
55 - nvmem-cells: A phandle to cpu_leakage data provided by a nvmem device.
56 - nvmem-cell-names: Should be "cpu_leakage"
58 - rockchip,threshold-freq: Clock frequency in KHz, it's used to reduce power
60 - rockchip,freq-limit: Only one cluster can contain the property, and the
61                        cluster's maximum frequency will be limited to its
62                        threshold frequency, if the other cluster's frequency
63                        is geater than or equal to its threshold frequency.
