Currently the 'interrupts' and 'interrupt-names' properties are defined being too generic to really describe any actual IRQ interface. Moreover the DW PCIe End-point devices are left with no IRQ signals. All of that can be fixed by adding the IRQ-related properties to the common DW PCIe DT-schemas in accordance with the hardware reference manual. The DW PCIe common DT-schema will contain the generic properties definitions with just a number of entries per property, while the DW PCIe RP/EP-specific schemas will have the particular number of items and the generic resource names listed. Note since there are DW PCI-based vendor-specific DT-bindings with the custom names assigned to the same IRQ resources we have no much choice but to add them to the generic DT-schemas in order to have the schemas being applicable for such devices. These names are marked as vendor-specific and should be avoided being used in new bindings in favor of the generic names.

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.
