Since for MMIO driver using FIFO registers, also known as tpm_tis, the default (and tbh recommended) behaviour is now the polling mode, the "tristate" workaround is no longer for benefit. If someone wants to explicitly enable IRQs for a TPM chip that should be without question allowed. It could very well be a piece hardware in the existing deny list because of e.g. firmware update or something similar. While at it, document the module parameter, as this was not done in 2006 when it first appeared in the mainline.

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.
