Even the driver already has implemented pin_dbg_show, it could be helpful to implement pin_conf_get for a more generic behavior. Contrary to the BCM2711, the BCM2835 SOC doesn't allow to read the bias config, so the implementation is limited to the basics. Keep ENOTSUPP here, because it's only used internally.

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.
