This is a patch set inspired by the recent patch Kai-Heng posted about
the HD-audio mic-mute LED control. Currently HD-audio driver deals
with the mute and mic-mute LED in several different ways: primarily
with the direct callback of vmaster hook and capture sync hook, while
another with the LED class device binding. The latter has been used
for binding with the platform device LEDs like Thinkpad, Dell,
Huawei. And, yet, recently we added our own LED classdev for the
mic-mute LED on some HP systems although they are controlled directly
with the callback; it's exposed, however, for the DMIC that is
governed by a different ASoC driver.
This patch set is an attempt to sort out and make them consistent:
namely,
* All LEDs are now controlled via LED class device
* The generic driver provides helper functions to easily build up the
LED class dev and the relevant mixer controls
* Conversion of the existing framework and clean ups
The patches are lightly tested in my side with a couple of machines
and also through hda-emu tests. Some devices receive new kcontrols
for the mute LED behavior (that have been missing so far), but
anything else look good though my tests.

In the end we already enabled the sync-write mode for most of HD-audio
controllers including Intel, and it's no big merit to keep the async
write mode for the rest. Let's make it as default and drop the
superfluous AZX_DCAPS_SYNC_WRITE bit flag.
Also, avoid to set the allow_bus_reset flag, which is a quite unstable
and hackish behavior that was needed only for some early platforms
(decades ago). The straight fallback to the single cmd mode is more
robust.

Set LED_CORE_SUSPENDRESUME to LED cdev flags, so that the LED core
would store and restore the LED status at suspend/resume.
In theory, the codec driver should be responsible for all LED bits,
but this might be safer and cover the overlooked cases.

Both mute and mic-mute LED callbacks do almost similar tasks with just
different bits. Factor out the common code and use them from the
callbacks for simplification.
This ended up with covering the forgotten stuff, too; e.g. VREF LED
handling required the temporary power up/down that was missing for the
mute LED, or some forgotten polarity checks are added.

Convert the mute LED handling in Sigmatel/IDT codec to the new vmaster
mute helper. A point to be cautiously handled is that the value
passed to the callback is inverted; the vmaster passes "enabled"
(0 = mute), while LED classdev passes "brightness" (1 = mute).
A positive side-effect by this change is that the driver gets also the
enum controls for the mute behavior like other drivers already had.

Convert the mute LED handling in Conexant codec to the new vmaster
mute helper. A point to be cautiously handled is that the value
passed to the callback is inverted; the vmaster passes "enabled"
(0 = mute), while LED classdev passes "brightness" (1 = mute).
Also the assignment of the default vmaster hook is moved at a later
point after the mute hook is set up. This assures no nested hook.
Finally, since we enable the mute-LED kcontrols always in the helper
side, the extra vmaster_mute_enum flag set up is dropped.

Convert the mute LED handling in Realtek codec to the new vmaster mute
helper. A point to be cautiously handled is that the value passed to
the callback is inverted; the vmaster passes "enabled" (0 = mute),
while LED classdev passes "brightness" (1 = mute).
The code in Thinkpad helper is also converted. In that case, just
call the new function and remove the open-code.

Like mic-mute LED handling, add a new helper to deal with the master
mute LED with LED classdev. Unlike the mic-mute case, the playback
master mute is hooked on vmaster, and we suppose no nested hooks
allowed there.
The classdev creation code is factored out to a common function that
is called from both mute and mic-mute LED helpers.

This patch converts the remaining user of
snd_hda_gen_add_micmute_led() in Realtek codec driver into the new
snd_hda_gen_add_micmute_led_cdev().
The Thinkpad helper code is updated accordingly, too.
Also, the usage of snd_hda_gen_fixup_micmute_led() is replaced with
either the local alc_fixup_micmute_led() or the explicit call of
snd_hda_gen_add_micmute_led_cdev() with NULL callback.

A new helper, snd_hda_gen_add_micmute_led_cdev(), is introduced here
for creating a LED classdev and setting up the hook to the capture
control for controlling the mic-mute LED to follow the capture switch
change. This will replace the existing users of
snd_hda_gen_add_micmute_led() in later patches.
Also, introduce a new kconfig CONFIG_SND_HDA_GENERIC_LEDS, to indicate
the usage of mute / mic-mute LED helpers. It's selected by the codec
drivers (Realtek, Conexant and Sigmatel), while it selects the
necessary LED class dependencies.

Instead of adding a special hook to trigger the mic-mute LED device,
call it always from the common callback function. It won't hurt even
if no corresponding led cdev is present.
This is basically a preliminary change for the later patches to
convert the all mic-mute LED handling to LED class cdev.

out common operations and making the card abstraction more solid.
- Continued work on cleaning up and improving the Intel drivers, along
with some new platform support for them.
- Fixes to make the Marvell SSPA driver work upstream.
- Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and

We fixed the regression of the speaker volume for some Thinkpad models
(e.g. T570) by the commit 54947cd64c ("ALSA: hda/realtek - Fix
speaker output regression on Thinkpad T570"). Essentially it fixes
the DAC / pin pairing by a static table. It was confirmed and merged
to stable kernel later.
Now, interestingly, we got another regression report for the very same
model (T570) about the similar problem, and the commit above was the
culprit. That is, by some reason, there are devices that prefer the
DAC1, and another device DAC2!
Unfortunately those have the same ID and we have no idea what can
differentiate, in this patch, a new fixup model "tpt470-dock-fix" is
provided, so that users with such a machine can apply it manually.
When model=tpt470-dock-fix option is passed to snd-hda-intel module,
it avoids the fixed DAC pairing and the DAC1 is assigned to the
speaker like the earlier versions.

Tegra194 has 4 SDO lines and with this configuration playback fails
for 44.1K/48K, 2-channel and 16-bps. It results in below print,
"aplay: pcm_write:2011: write error: Input/output error"
Below relation is used to derive stripe control and is referenced
from HD Audio Specification: Revision 1.0a.
{ ((num_channels * bits_per_sample) / number of SDOs) >= 8 }
Due to a legacy HW design problem, playback issue is hit while using
a stripe value resulting from above formula when ratio is '8'. Thus
it is recommended that the ratio must be greater than '8'. Since the
number of SDO lines is in powers of 2, next available ratio '16' is
used as a limiting factor on Tegra194 to workaround the problem.

Currently DMIC controls micmute LED via "audio mute LED trigger".
However, unlike Dell and Lenovo platforms, HP platforms don't provide a
way to control micmute LED via ACPI, it's controlled by HDA codec
instead.
So let's register an LED class for micmute so other subsystems like DMIC
can facilitate the codec-controlled LED.

A race exists between build_pcms() and build_controls() phases of codec
setup. Build_pcms() sets up notifier for jack events. If a monitor event
is received before build_controls() is run, the initial jack state is
lost and never reported via mixer controls.
The problem can be hit at least with SOF as the controller driver. SOF
calls snd_hda_codec_build_controls() in its workqueue-based probe and
this can be delayed enough to hit the race condition.
Fix the issue by invalidating the per-pin ELD information when
build_controls() is called. The existing call to hdmi_present_sense()
will update the ELD contents. This ensures initial monitor state is
correctly reflected via mixer controls.
