	help
	  This enables the Generic CPUfreq driver for ARM big.LITTLE platform.
	  This gets frequency tables from DT.

	depends on CPU_S3C2416
	help
	  This adds the CPUFreq driver for the Samsung S3C2416 and
	  S3C2450 SoC. The S3C2416 supports changing the rate of the
	  armdiv clock source and also entering a so called dynamic
	  voltage scaling mode in which it is possible to reduce the
	  core voltage of the cpu.

	  If in doubt, say N.

	tristate "Freescale i.MX6Q cpufreq support"
	depends on SOC_IMX6Q
	depends on REGULATOR_ANATOP
	help
	  This adds cpufreq driver support for Freescale i.MX6Q SOC.

	  If in doubt, say N.

config ARM_SPEAR_CPUFREQ
	bool "SPEAr CPUFreq support"
	depends on PLAT_SPEAR
	default y
	help
	  This adds the CPUFreq driver support for SPEAr SOCs.

config ARM_HIGHBANK_CPUFREQ
	tristate "Calxeda Highbank-based"
	depends on ARCH_HIGHBANK
	select CPU_FREQ_TABLE
	select GENERIC_CPUFREQ_CPU0
