The comment for this dbg_show says that it is supposed to return more than what the generic code is showing, including de-glitching. That's wrong because: - this chip does not support deglitching, - the code does not print anything extra compared to the generic handler, - its behavior is different because it skips unrequested GPIOs; the generic code prints their names if they're assigned There is an important difference, though. Previously, dbg_show would re-check some registers to see if they still match what the regmap thinks should be in there. This was semi-useful when develpoing the HW board because it immediately pointed to SPI wiring problem if a CS connection was missing (0xffs are easy to see). However, I do not think that this makes much sense -- and one could always do this in some other way if needed.

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.
