b0cd60f3e9 ALSA/ASoC: hda: clarify bus_get_link() and bus_link_get() helpers
We have two helpers with confusing names and different purposes.

Rename bus_get_link() and bus_get_link_at() as bus_get_hlink_by_name()
and bus_get_hlink_by_addr() respectively.

No functionality change

ef6f5494fa ALSA: hda/hdmi: Use only dynamic PCM device allocation
Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM
device mapping is obsolete nowadays. The maximum number of the simultaneously
usable PCM devices is equal to the HDMI codec converters.

Remove the extra PCM devices (beyond the detected converters) and force
the use of the dynamic PCM device allocation. The legacy code is removed.

I believe that all HDMI codecs have the jack sensing feature. Move the check
to the codec probe function and print a warning, if a codec without this
feature is detected.

3fd63658ca ASoC: Intel: Drop hdac_ext usage for codec device creation
To make snd_hda_codec_device_init() the only constructor for struct
hda_codec instances remaining tasks are:

1) no struct may wrap struct hda_codec as its base type
2) bus drivers (skylake and sof) which are the current hdac_ext users
   need to be adjusted to make use of newly added codec init and exit
   routines instead
3) as bus drivers (skylake and sof) are to be responsible for creating
   codec device and assigning it to hdac_hda_priv->codec,
   hdac_hda_dev_probe() has to be freed of that job

To keep git bisect happy, all of these in made in one-go.

ASoC: hdac_hda: Add endianness flag in snd_soc_component_driver
The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over an HDA DAI and as such should
have endianness applied.

ASoC: hdac_hda: Avoid unexpected match when pcm_name is "Analog"
pcm name can be "Analog" and "Alt Analog", cpcm->name can be
"Analog Codec DAI" and "Alt Analog Codec DAI". When pcm_name
is "Analog", "Analog Codec DAI" and "Alt Analog Codec DAI" are
both satisfy the 'if (strstr(cpcm->name, pcm_name))' condition,
which may cause the returned cpcm to be "Alt Analog Codec DAI".

Even if we get the pcm name by id, and "Analog Codec DAI" goes
into the loop before "Alt Analog Codec DAI", but I still think
we'd better have multiple insurances against unexpected return
values. After, we can correctly return the expected result
even if other relevant places are changed.

Due to ALSA-device vs ASoC-component organization differences, new

Move to the more generic set_stream() API to pass the hdac_stream

Align with recent change to forbid runtime suspend during codec
init in snd_hda_codec_device_new(), with matching call to
allow suspend at end of hdac_hda_codec_probe().

In snd-hda-intel, call to snd_hda_set_power_save() at end of
controller probe does the same thing, but ASoC controller drivers
do not modify runtime settings for codecs, so this has to be done
in codec drivers, and in this case in hdac_hda.

ASoC: hdac_hda: fix deadlock after PCM open error
Commit 5bd70440cb0a ("ASoC: soc-dai: revert all changes to DAI
startup/shutdown sequence"), introduced a slight change of semantics
to DAI startup/shutdown. If startup() returns an error, shutdown()
is now called for the DAI.

This causes a deadlock in hdac_hda which issues a call to
snd_hda_codec_pcm_put() in case open fails. Upon error, soc_pcm_open()
will call shutdown(), and pcm_put() ends up getting called twice. Result
is a deadlock on pcm->open_mutex, as snd_device_free() gets called from
within snd_pcm_open(). Typical task backtrace looks like this:

ASoC: hdac_hda: fix memleak on module unload
The hdac_hda remove implementation fails to free the hda codec
resources, leading to memleaks at module unload. This gap has been there
from the start, commit 6bae5ea94989 ("ASoC: hdac_hda: add asoc
extension for legacy HDA codec drivers").

Instead of duplicating the cleanup logic, use the common
snd_hda_codec_cleanup_for_unbind() to free the resources. Remove
existing code in hdac_hda to cleanup "codec.jackpoll_work" and call to
snd_hdac_regmap_exit(), as these are already done in
snd_hda_codec_cleanup_for_unbind().

The cleanup is done in ASoC component remove() callback and not in the
HDAC bus hdev_detach(). This is done to ensure the codec specific
cleanup routines are run before the parent card is freed.

ASoC: hdac_hda: fix race in device removal
When ASoC card instance is removed containing a HDA codec,
hdac_hda_codec_remove() may run in parallel with codec resume.
This will cause problems if the HDA link is freed with
snd_hdac_ext_bus_link_put() while the codec is still in
middle of its resume process.

To fix this, change the order such that pm_runtime_disable()
is called before the link is freed. This will ensure any
pending runtime PM action is completed before proceeding
to free the link.

This issue can be easily hit with e.g. SOF driver by loading and
unloading the drivers.

latter work is accessing codec device which could be already removed.

Here add the cancellation of jack-detecting work before codecs are actually
removed to avoid the race and fix the issue.

b60ee2e281 ASoC: hdac_hda: overwrite hdev type to HDA_DEV_ASOC
In ASoC driver, snd_hdac_device_register() will be called by
snd_hdac_ext_bus_device_init() and snd_hdac_device_unregister()
will called by snd_hdac_ext_bus_device_remove(). However when
ASoC codec driver call snd_hda_codec_device_new() to create a
new hda codec, it will assign snd_hda_codec_dev_free() to the
dev_free ops and snd_hda_codec_dev_free() will call
snd_hdac_device_unregister(). As a result, snd_hdac_device_unregister()
will be called twice in ASoC driver. To prevent it, we use hdev
type to determine if the hda codec is registered by legacy HDA
driver or ASoC driver and unregister device in  snd_hda_codec_dev_free()
only if it is a legacy HDA device.
This patch will overwrite the hdev type so that we can know it is
a ASoC device.

ASoC:hdac_hda:use correct format to setup hda codec
The current implementation of the hdac_hda codec results in zero-valued
samples on capture and noise with headset playback when SOF is used on
platforms with an on-board HDaudio codec. This is root-caused to SOF
using be_hw_params_fixup, and the prepare() call using invalid runtime
fields to determine the format.

This patch moves the format handling to the hw_params() callback, as
done already for hdac_hdmi, to make sure the fixed-up information is
taken into account but keeps the codec initialization in prepare() as
the stream_tag is only available at that time. Moving everything in the
prepare() callback is possible but the code is less elegant so this
two-step solution was chosen.

The solution was tested with the SST driver with no regressions, and all
the issues with SOF playback and capture are solved.

ASoC: codecs: constify snd_soc_dai_ops structures
The snd_soc_dai_ops structures are only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structures
const as well.

Done with the help of Coccinelle.

ASoC: hdac_hda: use devm_snd_soc_register_component()
Now we have devm_snd_soc_register_component().
Let's use it instead of snd_soc_register_component().

ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers
This patch adds a kernel module which is used by the legacy HDA
codec drivers as library. This implements hdac_ext_bus_ops to enable
the reuse of legacy HDA codec drivers with ASoC platform drivers.
