Our usage of runtime PM to control the hierarchy of power domains is slightly unusual and means that powering up a domain may fail in early system resume, as runtime PM is still disallowed at this stage. However the system suspend/resume path takes care of powering down/up the power domains in the order defined by the device parent/child and power-domain provider/consumer hierarachy. So we can just runtime resume all our power-domain devices to allow the power-up to work properly in the resume path. System suspend will still disable all domains as intended.

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.
