<title>ALSA: hda: intel: Allow repeatedly probing on codec configuration errors</title>

<id>c0f1886de7e173865f1a0fa7680a1c07954a987f</id>
<content type='text'>
It seems that a few recent AMD systems show the codec configuration
errors at the early boot, while loading the driver at a later stage
works magically.  Although the root cause of the error isn't clear,
it's certainly not bad to allow retrying the codec probe in such a
case if that helps.

This patch adds the capability for retrying the probe upon codec probe
errors on the certain AMD platforms.  The probe_work is changed to a
delayed work, and at the secondary call, it'll jump to the codec
probing.

Note that, not only adding the re-probing, this includes the behavior
changes in the codec configuration function.  Namely,
snd_hda_codec_configure() won't unregister the codec at errors any
longer.  Instead, its caller, azx_codec_configure() unregisters the
codecs with the probe failures *if* any codec has been successfully
configured.  If all codec probe failed, it doesn't unregister but let
it re-probed -- which is the most case we're seeing and this patch
tries to improve.

Even if the driver doesn't re-probe or give up, it will go to the
"free-all" error path, hence the leftover codecs shall be disabled /
deleted in anyway.

As reboot_notify callback is no longer used by the codec core, let's
get rid of the unused code.  Conexant codec needs a slight code change
as it used to call the reboot_notify at the codec removal, too.

<title>ALSA: hda: fix jack detection with Realtek codecs when in D3</title>

<id>a6e7d0a4bdb02a7a3ffe0b44aaa8842b7efdd056</id>
<content type='text'>
In case HDA controller becomes active, but codec is runtime suspended,
jack detection is not successful and no interrupt is raised. This has
been observed with multiple Realtek codecs and HDA controllers from
different vendors. Bug does not occur if both codec and controller are
active, or both are in suspend. Bug can be easily hit on desktop systems
with no built-in speaker.

The problem can be fixed by powering up the codec once after every
controller runtime resume. Even if codec goes back to suspend later, the
jack detection will continue to work. Add a flag to 'hda_codec' to
describe codecs that require this flow from the controller driver.
Modify __azx_runtime_resume() to use pm_request_resume() to make the
intent clearer.

Mark all Realtek codecs with the new forced_resume flag.

ASoC: Updates for v5.9

The biggest changes here one again come from Mormioto-san who has
continued his dilligent work cleaning up long standing issues in the
APIs, it's particularly nice to see the transition from digital_mute()
to mute_stream() finally completed. There's also been a lot of work on
the x86 code again, this time a big focus has been on cleaning up some
issues identified by various static tests, and on the Freescale systems.
Otherwise the biggest thing has been a lot of driver additions:

 - Convert users of digital_mute() to mute_stream().
 - Simplify I/O helper functions.
 - Add a helper for getting the RTD from a substream.
 - Many, many fixes and cleanups to the x86 code.
 - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
   MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
   Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
   of the first phones I worked on!) and TI J721e EVM.

<title>ALSA: Replace the word "slave" in vmaster API</title>

Follow the recent inclusive terminology guidelines and replace the
word "slave" in vmaster API.  I chose the word "follower" at this time
since it seems fitting for the purpose.

Note that the word "master" is kept in API, since it refers rather to
audio master volume control.

Also, while we're at it, a typo in comments is corrected, too.

<title>ALSA: hda: Skip controller resume if not needed</title>

<id>c4c8dd6ef807663e42a5f04ea77cd62029eb99fa</id>
<content type='text'>
The HD-audio controller does system-suspend and resume operations by
directly calling its helpers __azx_runtime_suspend() and
__azx_runtime_resume().  However, in general, we don't have to resume
always the device fully at the system resume; typically, if a device
has been runtime-suspended, we can leave it to runtime resume.

Usually for achieving this, the driver would call
pm_runtime_force_suspend() and pm_runtime_force_resume() pairs in the
system suspend and resume ops.  Unfortunately, this doesn't work for
the resume path in our case.  For handling the jack detection at the
system resume, a child codec device may need the (literally) forcibly
resume even if it's been runtime-suspended, and for that, the
controller device must be also resumed even if it's been suspended.

This patch is an attempt to improve the situation.  It replaces the
direct __azx_runtime_suspend()/_resume() calls with with
pm_runtime_force_suspend() and pm_runtime_force_resume() with a slight
trick as we've done for the codec side.  More exactly:

- azx_has_pm_runtime() check is dropped from azx_runtime_suspend() and
  azx_runtime_resume(), so that it can be properly executed from the
  system-suspend/resume path

- The WAKEEN handling depends on the card's power state now; it's set
  and cleared only for the runtime-suspend

- azx_resume() checks whether any codec may need the forcible resume
  beforehand.  If the forcible resume is required, it does temporary
  PM refcount up/down for actually triggering the runtime resume.

- A new helper function, hda_codec_need_resume(), is introduced for
  checking whether the codec needs a forcible runtime-resume, and the
  existing code is rewritten with that.
