patch_realtek.c has historically failed to properly configure the PC
Beep Hidden Register for the ALC256 codec (among others). Depending on
your kernel version, symptoms of this misconfiguration can range from
chassis noise, picked up by a poorly-shielded PCBEEP trace, getting
amplified and played on your internal speaker and/or headphones to loud
feedback, which responds to the "Headphone Mic Boost" ALSA control,
getting played through your headphones. For details of the problem, see
the patch in this series titled "ALSA: hda/realtek - Set principled PC
Beep configuration for ALC256", which fixes the configuration.
These symptoms have been most noticed on the Dell XPS 13 9350 and 9360,
popular laptops that use the ALC256. As a result, several model-specific
fixups have been introduced to try and fix the problem, the most
egregious of which locks the "Headphone Mic Boost" control as a hack to
minimize noise from a feedback loop that shouldn't have been there in
the first place.
Now that the underlying issue has been fixed, remove all these fixups.
Remaining fixups needed by the XPS 13 are all picked up by existing pin
quirks.
This change should, for the XPS 13 9350/9360
- Significantly increase volume and audio quality on headphones
- Eliminate headphone popping on suspend/resume
- Allow "Headphone Mic Boost" to be set again, making the headphone
jack fully usable as a microphone jack too.

[ This is rather a revival of the patch Tomas sent in months ago, but
applying only with the quirk model option -- tiwai ]
Hard coded coefficients to make Huawuei Matebook X right speaker
work. The Matebook X has a ALC298, please refer to bug 197801 on
how these numbers were reverse engineered from the Windows driver
The reversed engineered sequence represents a repeating pattern
of verbs, and the only values that are changing periodically are
written on indexes 0x23 and 0x25:
0x500, 0x23
0x400, VALUE1
0x500, 0x25
0x400, VALUE2
* skipped reading sequences (0x500 - 0xc00 sequences are ignored)
* static values from reverse engineering are used
NOTE: since a significant risk is still considered, this is provided
as an experimental fix that isn't applied as default for now. For
enabling the fix, you'll have to choose huawei-mbx-stereo via model
option of snd-hda-intel module.
If we get feedback from users that this works stably, we may apply it
per default.

Add a corresponding model list entry for ASUS G751 so that user can
test the quirk for another compatible machines more easily.

Like the previous commit for ALC662, let's give more comprehensive
list of model entries for ALC269 & co as well.

ALC662 and others have far more fixup entries than the model table.
Let's add more model string entries so that user can test / debug
without compiling kernels at each time.

For allowing user to apply the existing quirk on a machine with a
different SSID, add a new model string entry, alc700-ref.
The quirk itself was introduced in the commit b84e843644f2: "ALSA:
