1 Generic CPU0 cpufreq driver
3 It is a generic cpufreq driver for CPU0 frequency management. It
4 supports both uniprocessor (UP) and symmetric multiprocessor (SMP)
5 systems which share clock and voltage across all CPUs.
7 Both required and optional properties listed below must be defined
8 under node /cpus/cpu@0.
14 - operating-points: Refer to Documentation/devicetree/bindings/power/opp.txt for
15 details. OPPs *must* be supplied either via DT, i.e. this property, or
17 - clock-latency: Specify the possible maximum transition latency for clock,
18 in unit of nanoseconds.
19 - voltage-tolerance: Specify the CPU voltage tolerance in percentage.
23 Please refer to Documentation/devicetree/bindings/thermal/thermal.txt.
