An SPI TPM device managed directly on an embedded board using the SPI bus and some GPIO or similar line as IRQ handler will pass the IRQn from the TPM device associated with the SPI device. This is already handled by the SPI core, so make sure to pass this down to the core as well. (The TPM core habit of using -1 to signal no IRQ is dubious (as IRQ 0 is NO_IRQ) but I do not want to mess with that semantic in this patch.)

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
