Armada 3700 PCIe IP relies on the PCIe clock managed by this driver. For reasons related to the PCI core's organization when suspending/resuming, PCI host controller drivers must reconfigure their registers at suspend_noirq()/resume_noirq() which happens after suspend()/suspend_late() and before resume_early()/resume(). Device link support in the clock framework enforce that the clock driver's resume() callback will be called before the PCIe driver's. But, any resume_noirq() callback will be called before all the registered resume() callbacks. The solution to support PCIe resume operation is to change the "priority" of this clock driver PM callbacks to "_noirq()".

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.
