Currently the generic power domain will power off the domain if all devices in it have been stopped during system suspend. It is done by checking if the domain is active in genpd_sync_power_off, then disable it. However, for power domains supporting multiple low power states, it may have already entered 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. Then genpd_sync_power_off will keep it at the low power state instead of completely gate off it. 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. Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
