+config CPU_FREQ_CBE
+ tristate "CBE frequency scaling"
+ depends on CBE_RAS && PPC_CELL
+ default m
+ help
+ This adds the cpufreq driver for Cell BE processors.
+ For details, take a look at <file:Documentation/cpu-freq/>.
+ If you don't have such processor, say N
+
+config CPU_FREQ_CBE_PMI
+ bool "CBE frequency scaling using PMI interface"
+ depends on CPU_FREQ_CBE
+ default n
+ help
+ Select this, if you want to use the PMI interface to switch
+ frequencies. Using PMI, the processor will not only be able to run at
+ lower speed, but also at lower core voltage.
+
+config CPU_FREQ_MAPLE
+ bool "Support for Maple 970FX Evaluation Board"
+ depends on PPC_MAPLE
+ help
+ This adds support for frequency switching on Maple 970FX
+ Evaluation Board and compatible boards (IBM JS2x blades).
+
+config CPU_FREQ_PMAC
+ bool "Support for Apple PowerBooks"
+ depends on ADB_PMU && PPC32
+ help
+ This adds support for frequency switching on Apple PowerBooks,
+ this currently includes some models of iBook & Titanium
+ PowerBook.
+
+config CPU_FREQ_PMAC64
+ bool "Support for some Apple G5s"
+ depends on PPC_PMAC && PPC64
+ help
+ This adds support for frequency switching on Apple iMac G5,
+ and some of the more recent desktop G5 machines as well.
+
+config PPC_PASEMI_CPUFREQ
+ bool "Support for PA Semi PWRficient"
+ depends on PPC_PASEMI
+ default y
+ help
+ This adds the support for frequency switching on PA Semi
+ PWRficient processors.

+config POWERNV_CPUFREQ
+ tristate "CPU frequency scaling for IBM POWERNV platform"
+ depends on PPC_POWERNV
+ default y
+ help
+ This adds support for CPU frequency switching on IBM POWERNV
+ platform
