But, I am trying to use the pm_wake_lock/unlock API's under
"kernel/power/wakelock.c". I do not see any "public kernel headers", which
I can include in my driver and make calls to "pm_wake_lock/unlock". would
you have any thoughts one this ?
That is because the pm_wake_lock/unlock functions are only for the
userland compatibility interface, not the in-kernel driver interfaces.
From a driver, you will want to use the wakeup_source interfaces:
extern void __pm_stay_awake(struct wakeup_source *ws);
extern void __pm_relax(struct wakeup_source *ws);
...
and others as found in include/linux/pm_wakeup.h.
You can see how the AOSP code is using wakeup_sources to replace
wakelocks in their transition header which supports older drivers that
still use wakelocks:
