Using PMI, the processor will not only be able to run at 18 lower speed, but also at lower core voltage. 19 20config CPU_FREQ_MAPLE 21 bool "Support for Maple 970FX Evaluation Board" 22 depends on PPC_MAPLE 23 help 24 This adds support for frequency switching on Maple 970FX 25 Evaluation Board and compatible boards (IBM JS2x blades). 26 27config CPU_FREQ_PMAC 28 bool "Support for Apple PowerBooks" 29 depends on ADB_PMU && PPC32 30 help 31 This adds support for frequency switching on Apple PowerBooks, 32 this currently includes some models of iBook & Titanium 33 PowerBook. 34 35config CPU_FREQ_PMAC64 36 bool "Support for some Apple G5s" 37 depends on PPC_PMAC && PPC64 38 help 39 This adds support for frequency switching on Apple iMac G5, 40 and some of the more recent desktop G5 machines as well. 41 42config PPC_PASEMI_CPUFREQ 43 bool "Support for PA Semi PWRficient" 44 depends on PPC_PASEMI 45 default y 46 help 47 This adds the support for frequency switching on PA Semi 48 PWRficient processors. 49 50config POWERNV_CPUFREQ 51 tristate "CPU frequency scaling for IBM POWERNV platform" 52 depends on PPC_POWERNV 53 default y 54 help 55 This adds support for CPU frequency switching on IBM POWERNV 56 platform
