Wysocky" Cc: "cpufreq@vger.kernel.org" , Linux PM list , Vincent Guittot , Lukasz Majewski , Jonghwa Lee , Myungjoo Ham , linux-kernel , Lukasz Majewski , Andre Przywara , Daniel Lezcano , Kukjin Kim List-Id: linux-pm@vger.kernel.org The struct cpufreq_driver has been extended to embrace the information related to boost support. When "boost_mode" device tree attribute is defined for a platform, the boost_supported flag is set. Moreover boost related attributes were exported. Signed-off-by: Lukasz Majewski Signed-off-by: Myungjoo Ham Changes for v2: - Removal of struct cpufreq_boost - Removal of the CONFIG_CPU_FREQ_BOOST flag - low_level_boost with valid address when boost is supported Changes for v3: - Remove low level boost code - Move boost management code to cpufreq core code - Use boost_supported flag to indicate if driver supports over clocking --- drivers/cpufreq/exynos-cpufreq.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/cpufreq/exynos-cpufreq.c b/drivers/cpufreq/exynos-cpufreq.c index 32ec2f6..0420d47 100644 --- a/drivers/cpufreq/exynos-cpufreq.c +++ b/drivers/cpufreq/exynos-cpufreq.c @@ -265,6 +265,7 @@ static int exynos_cpufreq_cpu_exit(struct cpufreq_policy *policy) static struct freq_attr *exynos_cpufreq_attr[] = { &cpufreq_freq_attr_scaling_available_freqs, + &cpufreq_freq_attr_scaling_boost_freqs, NULL, }; @@ -360,6 +361,7 @@ static struct of_device_id exynos_cpufreq_of_match[] __initconst = { static int __init exynos_cpufreq_probe(struct platform_device *pdev) { + struct device_node *node = pdev->dev.of_node; int ret = -EINVAL; exynos_info = kzalloc(sizeof(struct exynos_dvfs_info), GFP_KERNEL); @@ -392,6 +394,8 @@ static int __init exynos_cpufreq_probe(struct platform_device *pdev) } locking_frequency = exynos_getspeed(0); + if (of_property_read_bool(node, "boost_mode")) + exynos_driver.boost_supported = 1; register_pm_notifier(&exynos_cpufreq_nb); -- 1.7.10.4
