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	select CPU_FREQ_TABLE
23	help
24	  This adds support for frequency switching on Maple 970FX
25	  Evaluation Board and compatible boards (IBM JS2x blades).
26
27config PPC_CORENET_CPUFREQ
28	tristate "CPU frequency scaling driver for Freescale E500MC SoCs"
29	depends on PPC_E500MC && OF && COMMON_CLK
30	select CPU_FREQ_TABLE
31	select CLK_PPC_CORENET
32	help
33	  This adds the CPUFreq driver support for Freescale e500mc,
34	  e5500 and e6500 series SoCs which are capable of changing
35	  the CPU's frequency dynamically.
36
37config CPU_FREQ_PMAC
38	bool "Support for Apple PowerBooks"
39	depends on ADB_PMU && PPC32
40	select CPU_FREQ_TABLE
41	help
42	  This adds support for frequency switching on Apple PowerBooks,
43	  this currently includes some models of iBook & Titanium
44	  PowerBook.
45
46config CPU_FREQ_PMAC64
47	bool "Support for some Apple G5s"
48	depends on PPC_PMAC && PPC64
49	select CPU_FREQ_TABLE
50	help
51	  This adds support for frequency switching on Apple iMac G5,
52	  and some of the more recent desktop G5 machines as well.
53
54config PPC_PASEMI_CPUFREQ
55	bool "Support for PA Semi PWRficient"
56	depends on PPC_PASEMI
57	select CPU_FREQ_TABLE
58	default y
59	help
60	  This adds the support for frequency switching on PA Semi
61	  PWRficient processors.
