Cristian Ciocaltea af66058d13 ASoC: nau8821: Add DMI quirk to bypass jack debounce circuit
[ Upstream commit 2b4eda7bf7 ]

Stress testing the audio jack hotplug handling on a few Steam Deck units
revealed that the debounce circuit is responsible for having a negative
impact on the detection reliability, e.g. in some cases the ejection
interrupt is not fired, while in other instances it goes into a kind of
invalid state and generates a flood of misleading interrupts.

Add new entries to the DMI table introduced via commit 1bc40efdaf
("ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect")
and extend the quirk logic to allow bypassing the debounce circuit used
for jack detection on Valve Steam Deck LCD and OLED models.

While at it, rename existing NAU8821_JD_ACTIVE_HIGH quirk bitfield to
NAU8821_QUIRK_JD_ACTIVE_HIGH.  This should help improve code readability
by differentiating from similarly named register bits.

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.
