The PCF2127 and PCF2129 have one output interrupt pin. The PCF2131 has two, named INT_A and INT_B. The hardware support that any interrupt source can be routed to either one or both of them. Force all interrupt sources to go to the INT A pin. Support to route any interrupt source to INT A/B pins is not supported by this driver at the moment.

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.
