Currently the hdmi i2s playback stream and hdmi spdif playback stream
are using the same name. So when they are enabled at the same time,
kernel will print this warning:
[ 2.201835] hdmi-audio-codec hdmi-audio-codec.1.auto: ASoC: Failed to

Assign different names to them to avoid that.

Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

Current hdmi-codec driver is using hdmi_controls for "ELD" control.
But, hdmi-codec driver might be used from many HDMIs. Thus, we need
to correspond device number, otherwise we will receive below error.
xxx: control x❌x:ELD:x is already present
This patch registers ELD control in .pcm_new by using
.device = rtd->pcm->device to corresponding to PCM stream.

DesignWare HDMI driver (= dw-hdmi) is supporting HDMI sound, and its
probe function was calling sound binding function multiple times as
same HDMI device different port.
Because of this behavior, commit 9731f82d60 ("ASoC: hdmi-codec: enable
multi probe for ...") was added for multi detection case.
But, this DesignWare HDMI detection/bind code was exchanged/adjusted by
commit 69497eb923 ("drm: bridge: dw-hdmi: Implement DRM bridge...").
Now, all DesignWare HDMI sound ports are detected as 1 bindng function.
Because of this, hdmi-codec multi detection support is no longer needed.
Thus, this patch removes
commit 9731f82d60 ("ASoC: hdmi-codec: enable multi probe for ..."),
and its related
commit 340327a62c ("ASoC: hdmi-codec: Fix hdmi_of_xlate_dai_name...")

Add user interface to provide channel mapping.
In a first step this control is read only.
As TLV type, the control provides all configuration available for
HDMI sink(ELD), and provides current channel mapping selected by codec
based on ELD and number of channels specified by user on open.
When control is called before the number of the channel is specified
(i.e. hw_params is set), it returns all channels set to UNKNOWN.

If a DAI specifies "#sound-dai-cells = <0>" in device-tree then
hdmi_of_xlate_dai_name() will be called with zero args, which it isn't
implemented to cope with. The resulting use of an uninitialised variable
for the id will usually result in an error like:
asoc-simple-card sound: parse error -11
asoc-simple-card: probe of sound failed with error -11
Fix this by using and id of zero if no arg is provided.

hdmi-codec driver is common HDMI sound driver,
but it doesn't care about multi sound ports.
For example, hdmi-codec driver is supporting 1 I2S and 1 SPDIF ports,
so, we can't use this driver if HDMI has 2 or more I2S ports.
And we would like to use multi detection.
For example, DesignWare HDMI driver is providing dw_hdmi_bind() to
DRM/KMS driver, and it will setups HDMI video/sound.
Note is that it will be called under for_each loop of ports.
int dw_hdmi_bind(xxx)
{
/* register hdmi-codec driver here */
}
static int xxx_probe(struct platform_device *pdev)
{
for_each_xxx(xx) {
...
dw_hdmi_bind(xxx);
...
}
}
This case, dw_hdmi_bind() would like to use hdmi-codec,
and it will be called multiple times for each ports.
Here, ASoC's CPU/Codec/Card bind will checks each "of_node" on DT,
and hdmi-codec driver is assuming its parent device for it.
But it doesn't care about case.
Thus, ASoC never detect correct sound card in this case.
To solve this issue, this patch checks each parent device,
and names "hdmi-hifi.x" in order to each ports.
And uses struct snd_soc_component_driver :: of_xlate_dai_name
for snd_soc_get_dai_name().

Current hdmi-codec driver is assuming that it will be registered
from HDMI driver. Because of this assumption, each callback function
has struct device pointer which is parent device (= HDMI).
Then, it can use dev_get_drvdata() to get private data.
OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs.
This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec
driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries
to bind DesignWare HDMI video driver, and HDMI codec driver
(= hdmi-codec). This case, above "parent device" of HDMI codec driver
is DRM/KMS driver and its "device" already has private data.
And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec
(= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise,
it never detect sound card.
Because of these reasons, some driver can't use dev_get_drvdata() to
get private data on hdmi-codec driver. This patch add new void pointer
on hdmi_codec_pdata for private data, and callback function will be
called with it.

ALSA doesn't know about all the different compressed audio formats,
so there is no interface to let userspace enumerate the formats that
are supported by the connected sink. Exporting the raw ELD bytes to
userspace allows an application to select the appropriate audio format
depending on the current capabilities of the connected HDMI sink device.
Usually userspace then just pretends to ALSA that the data is in one of
the raw 16-bit PCM audio formats and relies on the IEC controls to tell
the sink how to interpret the data.

The hdmi-codec is a platform device driver to be registered from
drivers of external HDMI encoders with I2S and/or spdif interface. The
driver in turn registers an ASoC codec for the HDMI encoder's audio
functionality.
The structures and definitions in the API header are mostly redundant
copies of similar structures in ASoC headers. This is on purpose to
avoid direct dependencies to ASoC structures in video side driver.
