7fe307117d ALSA: hda - Fix inconsistent Mic mute LED
The current code for controlling mic mute LED in patch_sigmatel.c
blindly assumes that there is a single capture switch.  But, there can
be multiple multiple ones, and each of them flips the state, ended up
in an inconsistent state.

For fixing this problem, this patch adds kcontrol to be passed to the
hook function so that the callee can check which switch is being
accessed.  In stac_capture_led_hook(), the state is checked as a
bitmask, and turns on the LED when all capture switches are off.

f8f1becfa4 ALSA: hda - Fix leftover ifdef checks after modularization
Since the commit [595fe1b702: ALSA: hda - Make
CONFIG_SND_HDA_CODEC_* tristate], the kconfig variables for the
generic parser and codec drivers can be "m" instead of boolean, but
some codes are left unchanged to check only #ifdef
CONFIG_SND_HDA_CODEC_XXX, which is no longer true for modules.
This patch fixes them by replacing with IS_ENABLED() macros.

276ab336b4 ALSA: hda - Improve loopback path lookups for AD1983
AD1983 has flexible loopback routes and the generic parser would take
wrong path confusingly instead of taking individual paths via NID 0x0c
and 0x0d.  For avoiding it, limit the connections at these widgets so
that the parser can think more straightforwardly.  This fixes the
regression of the missing line-in loopback on Dell machine.

d3c56568f4 ALSA: hda/realtek - Avoid invalid COEFs for ALC271X
We've seen often problems after suspend/resume on Acer Aspire One
AO725 with ALC271X codec as reported in kernel bugzilla, and it turned
out that some COEFs doesn't work and triggers the codec communication
stall.

Since these magic COEF setups are specific to ALC269VB for some PLL
configurations, the machine works even without these manual
adjustment.  So, let's simply avoid applying them for ALC271X.

75fae117a5 ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabled
Commit 384a48d715 "ALSA: hda: HDMI: Support codecs with fewer cvts
than pins" dynamically enabled each pin widget's PIN_OUT only when the
pin was actively in use. This was required on certain NVIDIA CODECs for
correct operation. Specifically, if multiple pin widgets each had their
mux input select the same audio converter widget and each pin widget had
PIN_OUT enabled, then only one of the pin widgets would actually receive
the audio, and often not the one the user wanted!

However, this apparently broke some Intel systems, and commit
6169b67361 "ALSA: hda - Always turn on pins for HDMI/DP" reverted the
dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA
CODECs.

This change supports either dynamic or static handling of PIN_OUT,
selected by a flag set up during CODEC initialization. This flag is
enabled for all recent NVIDIA GPUs.

3d692451ea ALSA: hda - Do not accept responses from non-existing codecs
While looking into some spurious responses, I found that the addr value was
treated a bit inconsistent: values 8..0xf will be treated as codec 0 and
values 0..7 will be treated as no error regardless of whether there is a codec
there, or not.

With this patch, all non-existing codecs will be treated equally.
In addition, printing rp and wp could help figuring out if the wp value is
reported wrongly from the controller or if something else is wrong.

3a00c6605b ALSA: hda/conexant - Re-implement OLPC XO workarounds via fixup
OLPC XO needs a few special handling.  Now these are implemented as a
fixup to the generic parser.

Obviously, the DC BIAS mode had to be added manually.  This is mainly
implemented in the mic_autoswitch hook, where the mic pins are
overwritten depending on the DC bias mode.  This also required the
override of the mic boost control, since the mic boost is applied only
when the DC mode is disabled.

In addition, the mic pins must be set dynamically at recording time
because these also control the LED.

so dumping them can be important. However, because they are undocumented and

(unlikely, but still) race remains.

On some AIO (All In One) models with the codec alc668

the system will switch the output to headphone and set the speaker to

this will bring loud noise to the headphone.

I tried to disable the corresponding EAPD, but it did not help to
eliminate the noise.

According to Takashi's suggestion, we use amp operation to replace the
pinctl modification for the automute, this really eliminate the noise.

7546abfb8e ALSA: hda - Increment default stream numbers for AMD HDMI controllers

In this patch, the default max number of streams for AMD HDMI
controllers is increased to 8, which  should suffice for most use
cases.  The overhead by this increase is more azx_dev struct and BDL
allocations, so it's negligible.  Of course, if the controller
provides a proper GCAP register, the register value would be used.

d8f66c71d5 ALSA: hda - Add warning texts when codec driver Kconfig doesn't match
When a Kconfig of a codec driver doesn't match with the controller
(CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic
probing.  Unfortunately kbuild can't give such a restriction, but at
least, it's possible to show a warning if such a condition is found.

595fe1b702 ALSA: hda - Make CONFIG_SND_HDA_CODEC_* tristate
So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons.  The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in.  And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.

But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.

That said, better to let people fallen into a pitfall than being too
smart and restrict something.  Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.
