From 45e12086263a53f16b489fc7f4f8f6348a688661 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 9 Aug 2013 14:04:55 +0200 Subject: cpufreq: fix EXYNOS drivers selection * remove superfluous pr_debug() call from exynos_cpufreq_init() (init errors are always logged anyway) * add dummy per-SoC type init functions to exynos-cpufreq.h * make per-SoC type cpufreq config options selectable * make CONFIG_ARM_EXYNOS_CPUFREQ config option invisible to user and automatically enable it when needed This patch fixes following issues: * EXYNOS per-SoC type cpufreq support (i.e. exynos4210-cpufreq.c) being always built if given SoC support was enabled (i.e. CPU_EXYNOS4210), even if common EXYNOS cpufreq support was disabled * inability to select cpufreq for each SoC type separately (it could be only enabled/disabled for all SoCs for which support was enabled) * EXYNOS5440 cpufreq support was always enabled when EXYNOS5440 support was enabled and couldn't be disabled Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Kyungmin Park Reviewed-by: Tomasz Figa Signed-off-by: Viresh Kumar --- drivers/cpufreq/Kconfig.arm | 36 ++++++++++++++++++++++++------------ 1 file changed, 24 insertions(+), 12 deletions(-) (limited to 'drivers/cpufreq/Kconfig.arm') diff --git a/drivers/cpufreq/Kconfig.arm b/drivers/cpufreq/Kconfig.arm index de4d5d93c3f..0fa204b244b 100644 --- a/drivers/cpufreq/Kconfig.arm +++ b/drivers/cpufreq/Kconfig.arm @@ -17,37 +17,47 @@ config ARM_DT_BL_CPUFREQ big.LITTLE platform.
