This patch adds IRQ support to the PASemi I2C controller driver to increase the performace of I2C transactions on platforms with PASemi I2C controllers. While primarily intended for Apple silicon platforms, this patch should also help in enabling IRQ support for older PASemi hardware as well should the need arise. This version of the patch has been tested on an M1 Ultra Mac Studio, as well as an M1 MacBook Pro, and userspace launches successfully while using the IRQ path for I2C transactions.

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.
