commit6f7ec77cc8upstream. The QFN20 part has a different GPIO/port function assignment. The configuration struct bit field ordered as TX/RX/RS485/WAKEUP/CLK which exactly matches GPIO0-3 for QFN24/28. However, QFN20 has a different GPIO to primary function assignment. Special case QFN20 to follow to properly detect which GPIOs are available.

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.
