Setting up HostNotify can be tricky. Support debugging by stating when a HostNotify alert was received independent of the irq being mapped. Especially useful with the in-kernel i2c testunit. Update documentation as well. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Reviewed-by: Andi Shyti <andi.shyti@kernel.org>
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 reStructuredText 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.
