Currently the generic power domain suspend code pm_genpd_suspend_noirq will try to power off a domain used by devices in genpd_sync_poweroff if its status is not GPD_STATE_ACTIVE. However, for power domains supporting multiple low power states, it may already enter an intermediate low power state by runtime PM before system suspend and the status is already GPD_STATE_POWER_OFF which results in then the power domain stay at an intermediate low power state during system suspend. Let's give the power domain a chance to switch to the deepest state in case it's already off but in an intermediate low power state. Due to power domain is alway off, so no need to check device wakeup case anymore.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
