During system suspend it is completely valid for devices to invoke TISCI commands during the noirq phase of the suspend path. Specifically this will always be seen for devices that define a power-domains DT property and make use of the ti_sci_pm_domains genpd implementation. The genpd_finish_suspend call will power off devices during the noirq phase, which will invoke TISCI. In order to support this, the ti_sci driver must switch to not use wait_for_completion_timeout during suspend, but instead rely on a manual check for if the completion is not yet done, and proceed only if this is the case.

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.
