2014-05-17cpufreq: nforce2: remove DEFINE_PCI_DEVICE_TABLE macroJingoo Han1-1/+1
Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro is deprecated. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2014-03-26cpufreq: Convert existing drivers to use cpufreq_freq_transition_{begin|end}Viresh Kumar1-2/+2
CPUFreq core has new infrastructure that would guarantee serialized calls to target() or target_index() callbacks. These are called cpufreq_freq_transition_begin() and cpufreq_freq_transition_end(). This patch converts existing drivers to use these new set of routines. Reviewed-by: Srivatsa S.

2013-10-16cpufreq: nforce2: don't initialize part of policy set by coreViresh Kumar1-1/+0
Many common initializations of struct policy are moved to core now and hence this driver doesn't need to do it. This patch removes such code. Most recent of those changes is to call ->get() in the core after calling ->init(). Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2013-10-16cpufreq: add new routine cpufreq_verify_within_cpu_limits()Viresh Kumar1-3/+1
Most of the users of cpufreq_verify_within_limits() calls it for limiting with min/max from policy->cpuinfo. We can make that code simple by introducing another routine which will do this for them automatically. This patch adds another routine cpufreq_verify_within_cpu_limits() and updates others to use it.

2013-08-10cpufreq: Drop the owner field from struct cpufreq_driverViresh Kumar1-1/+0
We don't need to set .owner = THIS_MODULE any more in cpufreq drivers as this field isn't used any more by the cpufreq core. This patch removes it and updates all dependent drivers accordingly.

2013-04-02cpufreq: drivers: Remove unnecessary assignments of policy-> membersViresh Kumar1-4/+2
Some assignments of policy-> min/max/cur/cpuinfo.min_freq/cpuinfo.max_freq aren't required as part of it is done by cpufreq driver or cpufreq core. Remove them. At some places we merge multiple lines together too. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Rafael J.

2013-04-02cpufreq: Notify all policy->cpus in cpufreq_notify_transition()Viresh Kumar1-3/+2
policy->cpus contains all online cpus that have single shared clock line. And their frequencies are always updated together. Many SMP system's cpufreq drivers take care of this in individual drivers but the best place for this code is in cpufreq core. This patch modifies cpufreq_notify_transition() to notify frequency change for all cpus in policy->cpus and hence updates all users of this API.

2012-01-27cpufreq: Add support for x86 cpuinfo auto loading v4Andi Kleen1-0/+8
This marks all the x86 cpuinfo tables to the CPU specific device drivers, to allow auto loading by udev. This should simplify the distribution startup scripts for this greatly. I didn't add MODULE_DEVICE_IDs to the centrino and p4-clockmod drivers, because those probably shouldn't be auto loaded and the acpi driver be used instead (not fully sure on that, would appreciate feedback) The old nforce drivers autoload based on the PCI ID. ACPI cpufreq is autoloaded in another patch. v3: Autoload gx based on PCI IDs only.
