config CPU_FREQ_CBE tristate "CBE frequency scaling" depends on CBE_RAS && PPC_CELL select CPU_FREQ_TABLE default m help This adds the cpufreq driver for Cell BE processors. For details, take a look at . 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 select CPU_FREQ_TABLE help This adds support for frequency switching on Maple 970FX Evaluation Board and compatible boards (IBM JS2x blades). config MPC85xx_CPUFREQ bool "Support for Freescale MPC85xx CPU freq" depends on PPC_85xx && PPC32 && !PPC_E500MC default n help This adds support for dynamic frequency switching on Freescale MPC85xx by cpufreq interface. MPC8536 and P1022 have a JOG feature, which provides a dynamic mechanism to lower or raise the CPU core clock at runtime. config QORIQ_CPUFREQ tristate "CPU frequency scaling driver for Freescale QorIQ SoCs" depends on OF && COMMON_CLK select CLK_QORIQ help This adds the CPUFreq driver support for Freescale QorIQ SoCs which are capable of changing the CPU's frequency dynamically. config CPU_FREQ_PMAC bool "Support for Apple PowerBooks" depends on ADB_PMU && PPC32 select CPU_FREQ_TABLE 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 select CPU_FREQ_TABLE 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 select CPU_FREQ_TABLE default y help This adds the support for frequency switching on PA Semi PWRficient processors.
