Modify the way the debugfs interface works in gpio-mockup. Introduce the concept of dummy pull config which will keep the mockup lines in known state. The pull values can be modified by writing to the debugfs files corresponding to lines. Lines in input mode always report the current pull value, lines in output mode change the line value but it will revert back to the one specified by current pull when released.

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.
