* 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 <b.zolnierkie@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Reviewed-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
