Merge branch 'for-next' of https://git.kernel.org/pub/scm/linux/kernel/git/mzx/devfreq
Pull devfreq framework changes for v4.21 from MyungJoo Ham:
"This includes the suspend-frequency support for devfreq, which is
similar with suspend_freq in cpufreq."
* 'for-next' of https://git.kernel.org/pub/scm/linux/kernel/git/mzx/devfreq:
PM / devfreq: add devfreq_suspend/resume() functions
PM / devfreq: add support for suspend/resume of a devfreq device
PM / devfreq: refactor set_target frequency function
