To support multiple codecs per SoundWire link, we have to assign multiple
CPU DAIs to different DAI links sharing the same physical link. This is
not possible with the existing code since we assume that only 'Pin2' is
used for playback and 'Pin3' used for capture - additional DAIs cannot
be handled.
This patch enables more CPU DAIs to be used, e.g. "SDW0 Pin2",
"SDW0 Pin3", and "SDW0 Pin4" for SDW0-Playback-SimpleJack,
SDW0-Capture-SimpleJack, and SDW0-Playback-SmartAmp DAI links on physical
link #0.

We append codec type to dailink name to distinguish different dailink
on the same sdw link and direction. But we could create multi dailinks
for a codec and the dailink name will be duplicated if we append codec
type to the dailink name.
Appending dai type instead of codec type can solve the issue.
For example, if a codec supports JACK on dai 0 and AMP on dai 1, the
existing code will create dailinks
SDW0-Playback-SimpleJack or SDW0-Playback-SmartAmp for both dailinks,
and it will be SDW0-Playback-SimpleJack for dailink 0 and
SDW0-Playback-SmartAmp for dailink 1 after this change.
Then codec type is not used any more and can be removed.

The existing code create a dailink for a codec. However, we may need
multi dailinks for a codec. This commit adds a new struct in
sof_sdw_codec_info{} to store the dai info of a codec.
The initial assumption if that we will create at most 3 dailink types
for a codec, since this is the max known with upcoming SDCA devices. We
may need to increase this number as new SDCA 'functions' become available.
One strong assumption is that all dailinks exposed are independent, as per
SDCA directions.
This commit just moves some items into the new sof_sdw_dai_info struct.
There is no function changed. Multi dais supported will be added in the

Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:
This patch series handles a few issues related to the ES8316 audio
codec, discovered while doing some testing on the Rock 5B board.
When using the codec through the generic audio graph card, there are at
least two calls of es8316_set_dai_sysclk(), with the effect of limiting
the allowed sample rates according to the MCLK/LRCK ratios supported by
the codec:
1. During audio card setup, to set the initial MCLK - see
asoc_simple_init_dai().
2. Before opening a stream, to update MCLK, according to the stream
sample rate and the multiplication factor - see
asoc_simple_hw_params().
In some cases the initial MCLK might be set to a frequency that doesn't
match any of the supported ratios, e.g. 12287999 instead of 12288000,
which is only 1 Hz below the supported clock, as that is what the
hardware reports. This creates an empty list of rate constraints, which
is further passed to snd_pcm_hw_constraint_list() via
es8316_pcm_startup(), and causes the following error on the very first
access of the sound card:
$ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav
Broken configuration for playback: no configurations available: Invalid argument
Setting of hwparams failed: Invalid argument
Note that all subsequent retries succeed thanks to the updated MCLK set
at point 2 above, which uses a computed frequency value instead of a
reading from the hardware registers. Normally this would have mitigated
the issue, but es8316_pcm_startup() executes before the 2nd call to
es8316_set_dai_sysclk(), hence it cannot make use of the updated
constraints.
Since es8316_pcm_hw_params() performs anyway a final validation of MCLK
against the stream sample rate and the supported MCLK/LRCK ratios, fix
the issue by ensuring that sysclk_constraints list is only set when at
least one supported sample rate is autodetected by the codec.

The following error occurs when trying to restore a previously saved
ALSA mixer state (tested on a Rock 5B board):
$ alsactl --no-ucm -f /tmp/asound.state store hw:Analog
$ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog
alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument
According to ES8316 datasheet, the register at address 0x2B, which is
related to the above mixer control, contains by default the value 0xB0.
Considering the corresponding ALC target bits (ALCLVL) are 7:4, the
control is initialized with 11, which is one step above the maximum
value allowed by the driver:
ALCLVL | dB gain
-------+--------
0000 | -16.5
0001 | -15.0
0010 | -13.5
.... | .....
0111 | -6.0
1000 | -4.5
1001 | -3.0
1010 | -1.5
.... | .....
1111 | -1.5
The tests performed using the VU meter feature (--vumeter=TYPE) of
arecord/aplay confirm the specs are correct and there is no measured
gain if the 1011-1111 range would have been mapped to 0 dB:
dB gain | VU meter %
--------+-----------
-6.0 | 30-31
-4.5 | 35-36
-3.0 | 42-43
-1.5 | 50-51
0.0 | 50-51
Increment the max value allowed for ALC Capture Target Volume control,
so that it matches the hardware default. Additionally, update the
related TLV to prevent an artificial extension of the dB gain range.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
The topology file and the machine driver rely on common definitions
for the dailink stream_name. To avoid any backwards-compatibility
problems, the machine driver stream names are set in stone and cannot
be modified.
This is problematic when we try to name some of the topology widgets
after the stream_name, since the widget name is limited to 44
characters
tools/include/uapi/sound/asound.h:#define SNDRV_CTL_ELEM_ID_NAME_MAXLEN 44
Existing examples include "Analog Playback and Capture" for HDaudio
dailinks, which leaves less than 20 chars to identify widgets/controls
with a meaningful name.
Since the 44-char limit is part of the UAPI definitions, we assumed
there is no way to increase it.
This patchset suggests instead a partial match which allows topology
files to use a shorter stream_name, which in turn allows for
self-explanatory widget names that comply with the 44-char limit.
This should not break any existing setup but with the introduction of
a partial match new dailinks should be named carefully to avoid
