Depending on the SoC/platform, additional devices may be part of the PSCI PM domain topology. This is the case with 'qcom,rpmh-rsc' device, for example, even if this is not yet visible in the corresponding DTS-files. Without going into too much details, a device like the 'qcom,rpmh-rsc' may have HW constraints that needs to be obeyed to, before a domain idlestate can be picked. Therefore, let's implement the ->sync_state() callback to receive a notification when all consumers of the PSCI PM domain providers have been attached/probed to it. In this way, we can make sure all constraints from all relevant devices, are taken into account before allowing a domain idlestate to be picked.

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.
