2 tristate "CBE frequency scaling"
3 depends on CBE_RAS && PPC_CELL
7 This adds the cpufreq driver for Cell BE processors.
8 For details, take a look at <file:Documentation/cpu-freq/>.
9 If you don't have such processor, say N
11 config CPU_FREQ_CBE_PMI
12 bool "CBE frequency scaling using PMI interface"
13 depends on CPU_FREQ_CBE
16 Select this, if you want to use the PMI interface to switch
17 frequencies. Using PMI, the processor will not only be able to run at
18 lower speed, but also at lower core voltage.
21 bool "Support for Maple 970FX Evaluation Board"
25 This adds support for frequency switching on Maple 970FX
26 Evaluation Board and compatible boards (IBM JS2x blades).
28 config PPC_CORENET_CPUFREQ
29 tristate "CPU frequency scaling driver for Freescale E500MC SoCs"
30 depends on PPC_E500MC && OF && COMMON_CLK
32 select CLK_PPC_CORENET
34 This adds the CPUFreq driver support for Freescale e500mc,
35 e5500 and e6500 series SoCs which are capable of changing
36 the CPU's frequency dynamically.
39 bool "Support for Apple PowerBooks"
40 depends on ADB_PMU && PPC32
43 This adds support for frequency switching on Apple PowerBooks,
44 this currently includes some models of iBook & Titanium
47 config CPU_FREQ_PMAC64
48 bool "Support for some Apple G5s"
49 depends on PPC_PMAC && PPC64
52 This adds support for frequency switching on Apple iMac G5,
53 and some of the more recent desktop G5 machines as well.
55 config PPC_PASEMI_CPUFREQ
56 bool "Support for PA Semi PWRficient"
61 This adds the support for frequency switching on PA Semi
62 PWRficient processors.
