After all conversions, driver->ops became a must in most places
(except for the codec power setup which might be called before binding
to the codec driver), hence we can get rid of the superfluous
driver->ops NULL checks, too.

Now that all patch_ops usage have been converted to the new
hda_codec_ops probe, we can drop patch_ops from the hda_codec,
together with the calls of patch_ops callbacks.
The hda_codec_ops.free callback is removed as all have been replaced
with the new remove callback.
Also, correct comments mentioning "patch"; it's replaced with "codec
driver".

Until now, we use "patch_ops" embedded in hda_codec object for
defining the callbacks that are used in various places to manage
HD-audio codec. But from the device driver POV, this should have been
rather the driver ops, instead of the callbacks in the codec object.
This patch defines the driver ops for HD-audio codec driver as the
replacement. We reuse the same struct hda_codec_ops, and this is put
as hda_codec_driver.ops. When the driver->ops callbacks are defined,
they are called primarily instead of codec->patch_ops callbacks.
With converting to the driver ops, there is no need to pass the ugly
patch_ops handling in hda_device_id tables. That is, driver_data
field of hda_device_id becomes really optional and it can be used for
passing the codec-specific data (e.g. specifying a model).
The codec entries after the conversion should be with HDA_CODEC_ID()
and co, instead of the former HDA_CODEC_ENTRY().
Once after converting all codec drivers to use driver ops, we can get
rid of codec patch_ops.

To avoid such issue, split the dai array into HDMI and non HDMI array and
register them conditionally:
for HDMI hdev only register the dais needed for HDMI
for non HDMI hdev do not register the HDMI dais.

The array size is irrelevant with SNDRV_CARDS. dev_index is from
codec address and the available codec number is HDA_MAX_CODECS.
Also, hda_pvt->fw is for a temporary use, no need to add a new extra

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device mapping is obsolete nowadays.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.

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.

- Use of NHLT ACPI table to reduce the amount of quirking required for
Intel systems.
- Some building blocks for use in forthcoming Intel AVS driver for
legacy Intel DSP firmwares.
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with

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.

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.

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:

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: Fixes for v5.5
This is mostly driver specific fixes, plus an error handling fix
in the core. There is a rather large diffstat for the stm32 SAI
driver, this is a very large but mostly mechanical update which
wraps every register access in the driver to allow a fix to the
locking which avoids circular locks, the active change is much
smaller and more reasonably sized.

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.

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.

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.

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.

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

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.
