Rather than letting device driver be responsible to call devfreq_suspend_device() or devfreq_dev_suspend(),would there be any problems in using pm notifier here? (calling the event handler with DEVFREQ_GOV_SUSPEND/RESUME at pm notifier, stopping them earlier and resuming tham later)
What devfreq-core and devfreq-governors do with suspend/resume is handling the delayed workqueue and it does not have anything to do with device-specific tasks. Thus, having each device driver handle device-specifics with its own pm_ops and having devfreq-core stop sampling seem appropriate.
Putting another burden to each device driver (to call devfreq_suspend/resume_device() at its pm_ops) for an obvious task that could be done at core doesn't seem fair.
Thank you.
Cheers!

This patchset updates devfreq core to add support for devices
which can idle. When device idleness is detected perhaps
through runtime-pm, need some mechanism to suspend devfreq
load monitoring and resume when device is back online.
patch 1 introduce core design changes - per device work, decouple
delayed work from core and event based interaction.
patch 2 add devfreq suspend and resume apis.
patch 3 current frequency bug fix and add new sysfs attribute for
governor predicted next target frequency.
The existing devfreq apis are kept intact. Two new apis
devfreq_suspend_device() and devfreq_resume_device() are
added to support suspend/resume of device devfreq.

Add devfreq suspend/resume apis for devfreq users. This patch
supports suspend and resume of devfreq load monitoring, required
for devices which can idle.

I'd call the new functions devfreq_dev_suspend() and devfreq_dev_resume(),
respectively, because the names you're using currently suggest that the
device itself is suspended/resumed, which isn't the case.
Thanks,
Rafael

devfreq_add_device() and devfreq_remove_device() are two existing APIs.
I did follow same naming pattern to maintain uniformity and introduced
devfreq_suspend_device() and devfreq_resume_device() functions.
Do you suggest to follow devfreq_dev_xxx pattern even for existing APIs?
