[PATCH V5 1/2] cpufreq: Mark ARM drivers with CPUFREQ_NEED_INITIAL_FREQ_CHECK flag

by Viresh Kumar

Sometimes boot loaders set CPU frequency to a value outside of frequency table present with cpufreq core. In such cases CPU might be unstable if it has to run on that frequency for long duration of time and so its better to set it to a frequency which is specified in frequency table. On some systems we can't really say what frequency we're running at the moment and so for these we shouldn't check if we are running at a frequency present in frequency table. And so we really can't force this for all the cpufreq drivers. Hence we are created another flag here: CPUFREQ_NEED_INITIAL_FREQ_CHECK that will be marked by platforms which want to go for this check at boot time. Initially this is done for all ARM platforms but others may follow if required. Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- V4->V5: - Inverted flag, moved to CPUFREQ_NEED_INITIAL_FREQ_CHECK instead of CPUFREQ_SKIP_INITIAL_FREQ_CHECK and so this patch does it now for all the ARM drivers. -

[PATCH V4 1/2] cpufreq: Mark x86 drivers with CPUFREQ_SKIP_INITIAL_FREQ_CHECK flag

by Viresh Kumar

On some systems we can't really say what frequency we're running at the moment and so for these we shouldn't check if we are running at a frequency present in frequency table. For now mark all x86 drivers with this flag: CPUFREQ_SKIP_INITIAL_FREQ_CHECK. This patch also defines this macro. It will be used in cpufreq.c in the next patch.
