So where's the patch adding callers to this code?
If this cannot be done from regular driver suspend/resume calls, this probably should be done from cpu_pm notifiers CPU_PM_ENTER and CPU_PM_EXIT. We should also do the same for GPIO BTW.
BTW, the subject line is wrong here, it should be "pinctrl" :)
