This adds support for legacy INTx interrupts received from other PCIe devices and which are reported by a new INTx irq chip. With this change, kernel can distinguish between INTA, INTB, INTC and INTD interrupts. Note that for this support, device tree files has to be properly adjusted to provide "interrupts" or "interrupts-extended" property with intx interrupt source, "interrupt-names" property with "intx" string and also 'interrupt-controller' subnode must be defined. If device tree files do not provide these nodes then driver would work as before.

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.
