Ivan Lipski a488528a71 drm/amd/display: Add an hdmi_hpd_debounce_delay_ms module 
commit 6a681cd903 upstream.

[Why&How]
Right now, the HDMI HPD filter is enabled by default at 1500ms.

We want to disable it by default, as most modern displays with HDMI do
not require it for DPMS mode.

The HPD can instead be enabled as a driver parameter with a custom delay
value in ms (up to 5000ms).

Fixes: c918e75e1e ("drm/amd/display: Add an HPD filter for HDMI")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4859

README 

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.
