1config CPU_FREQ_CBE 2 tristate "CBE frequency scaling" 3 depends on CBE_RAS && PPC_CELL 4 default m 5 help 6 This adds the cpufreq driver for Cell BE processors. 7 For details, take a look at <file:Documentation/cpu-freq/>. 8 If you don't have such processor, say N 9 10config CPU_FREQ_CBE_PMI 11 bool "CBE frequency scaling using PMI interface" 12 depends on CPU_FREQ_CBE 13 default n 14 help 15 Select this, if you want to use the PMI interface to switch 16 frequencies. Using PMI, the processor will not only be able to run at 17 lower speed, but also at lower core voltage. 18 19config CPU_FREQ_MAPLE 20 bool "Support for Maple 970FX Evaluation Board" 21 depends on PPC_MAPLE 22 help 23 This adds support for frequency switching on Maple 970FX 24 Evaluation Board and compatible boards (IBM JS2x blades). 25 26config PPC_CORENET_CPUFREQ 27 tristate "CPU frequency scaling driver for Freescale E500MC SoCs" 28 depends on PPC_E500MC && OF && COMMON_CLK 29 select CLK_QORIQ 30 help 31 This adds the CPUFreq driver support for Freescale e500mc, 32 e5500 and e6500 series SoCs which are capable of changing 33 the CPU's frequency dynamically. 34 35config CPU_FREQ_PMAC 36 bool "Support for Apple PowerBooks" 37 depends on ADB_PMU && PPC32 38 help 39 This adds support for frequency switching on Apple PowerBooks, 40 this currently includes some models of iBook & Titanium 41 PowerBook. 42 43config CPU_FREQ_PMAC64 44 bool "Support for some Apple G5s" 45 depends on PPC_PMAC && PPC64 46 help 47 This adds support for frequency switching on Apple iMac G5, 48 and some of the more recent desktop G5 machines as well. 49 50config PPC_PASEMI_CPUFREQ 51 bool "Support for PA Semi PWRficient" 52 depends on PPC_PASEMI 53 default y 54 help 55 This adds the support for frequency switching on PA Semi 56 PWRficient processors. 57 58config POWERNV_CPUFREQ 59 tristate "CPU frequency scaling for IBM POWERNV platform" 60 depends on PPC_POWERNV 61 default y 62 help 63 This adds support for CPU frequency switching on IBM POWERNV 64 platform 65
