-----x-------------x----------------
Most of the drivers do following in their ->target_index() routines:
struct cpufreq_freqs freqs; freqs.old = old freq... freqs.new = new freq...
cpufreq_notify_transition(policy, &freqs, CPUFREQ_PRECHANGE);
/* Change rate here */
cpufreq_notify_transition(policy, &freqs, CPUFREQ_POSTCHANGE);
This is replicated over all cpufreq drivers today and there doesn't exists a good enough reason why this shouldn't be moved to cpufreq core instead.
There are few special cases though, like exynos5440, which doesn't do everything on the call to ->target_index() routine and call some kind of bottom halves for doing this work, work/tasklet/etc..
They may continue doing notification from their own code and so this patch introduces another flag: CPUFREQ_NO_NOTIFICATION, which will be set by such drivers.
This is Fifth part of my cleanup work for CPUFreq, first three are (And obviously its rebased over them):
1: cpufreq: Introduce cpufreq_table_validate_and_show() https://lkml.org/lkml/2013/8/8/263
2: cpufreq: define generic routines for cpufreq drivers https://lkml.org/lkml/2013/8/10/48
3. CPUFreq: Implement light weight ->target(): for 3.13 https://lkml.org/lkml/2013/8/13/349
4. CPUFreq: set policy->cur in cpufreq core instead of drivers https://lkml.org/lkml/2013/8/14/288
All these are pushed here: https://git.linaro.org/gitweb?p=people/vireshk/linux.git%3Ba=shortlog%3Bh=re...
