[PATCH 4/4] PM: Move clock-related definitions and headers to separate file

Rafael J. Wysocki
2011-08-08T22:32:25Z

Since the PM clock management code in drivers/base/power/clock_ops.c
is used for both runtime PM and system suspend/hibernation, the
definitions of data structures and headers related to it should not
be located in include/linux/pm_rumtime.h. Move them to a separate
header file.
