According to the comment, board files used to specify 1 ms for the debounce time. gpiod_set_debounce() needs the debounce time to be specified in units of microseconds, so make sure to multiply the value by 1000. Note that, according to the git log, the board files actually did specify 1 us for bounce times, but that seems really low. Device tree bindings for this type of GPIO typically specify the debounce times in milliseconds, so setting this default value to 1 ms seems like it would be somewhat safer.

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.
