Armada 3700 PCIe IP relies on the pinctrl IP managed by this driver. For reasons related to the PCI core's organization when suspending/resuming, PCI host controller drivers must reconfigure their register at suspend_noirq()/resume_noirq() which happens after suspend()/suspend_late() and before resume_early()/resume(). In the current state, after resuming from a suspend to RAM cycle the PCIe IP is reconfigured before the pinctrl one which produces an interrupt storm. The solution to support PCIe resume operation is to change the "priority" of this pinctrl driver PM callbacks to "_noirq()".

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.
