The parent SSI of a multi-SSI setup must be fully setup, started and
stopped since it is also part of the playback/capture setup. So only
skip the SSI (as per commit 203cdf51f2 ("ASoC: rsnd: SSI parent cares
SWSP bit") and commit 597b046f0d ("ASoC: rsnd: control SSICR::EN
correctly")) if the SSI is parent outside of a multi-SSI setup.

Sound card disconnecting operation was needed when "sound driver" was
unbinded without unbinding "sound card".
In such case, sound driver should be stopped even though it was
playbacking/capturing. Otherwise clock open/close counter mismatch happen.
One headache was that we can't skip unbind in error case because unbind
operation doesn't check return value from each drivers.
snd_soc_disconnect_sync() was added for these purpose, and Renesas
sound card only is used it.
But now, ALSA SoC automatically disconnect sound card when sound driver
was unbinded. Thus, snd_soc_disconnect_sync() is no longer needed.
This patch removes it.

Unlike other format-related DAI parameters, rdai->bit_clk_inv flag
is not properly re-initialized when setting format for new stream
processing. The inversion, if requested, is then applied not to default,
but to a previous value, which leads to SCKP bit in SSICR register being
set incorrectly.
Fix this by re-setting the flag to its initial value, determined by format.

Renesas sound device has many IPs and many situations.

To avoid duplicate DVC kctrl registration when MIXer was used,
it had original flags.
But it was issue when sound card was re-binded, because
no one can't cleanup this flags then.
To solve this issue, commit 9c698e8481 ("ASoC: rsnd: tidyup

card->controls, because if card was re-binded, these were cleanuped
automatically. This patch could solve re-binding issue.
But, it start to avoid MIX kctrl.

To allow multiple MIX registration: check registered rsnd_kctrl_cfg

OTOH, in CTU case, subID indicates CTU channel, and register settings
is based on it. This means regmap read/write function needs to care it.
This patch fixup this issue. It can't play MIXed sound without this
patch.

For TDM debug purpose, indicating Channel and Mode is very
useful. This patch indicate it if it has #define DEBUG

Current rsnd dvc.c is using flags to avoid duplicating register for
MIXer case. OTOH, commit e894efef9a ("ASoC: core: add support to card
rebind") allows to rebind sound card without rebinding all drivers.
Because of above patch and dvc.c flags, it can't re-register kctrl if
only sound card was rebinded, because dvc is keeping old flags.
(Of course it will be no problem if rsnd driver also be rebinded,
but it is not purpose of above patch).
This patch checks current card registered kctrl when registering.
In MIXer case, it can avoid duplicate register if card already has same
kctrl. In rebind case, it can re-register kctrl because card registered
kctl had been removed when unbinding.
This patch is updated version of commit b918f1bc7f ("ASoC: rsnd: DVC
kctrl sets once")

ssi.c only is using rsnd_ssi_is_dma_mode().
Let's move it as static function.

rsnd_parse_connect_ssiu_compatible() is doing
- using rsnd_ssiu_id(), but we use it via rsnd_mod_id()
- we can break loop if rsnd_dai_connect() was called
This patch fixup these.

commit c0ea089dba ("ASoC: rsnd: rsnd_mod_name() handles both name and
ID") merged "name" and "ID" on rsnd_mod_name() to handle sub-ID
(= for CTU/BUSIF).
Then, it decided to share static char to avoid pointless memory.
But, it doesn't work correctry in below case, because last called
name will be used.
dev_xxx(dev, "%s is connected to %s\n",
rsnd_mod_name(mod_a), /* ssiu[00] */
rsnd_mod_name(mod_b)); /* ssi[0] */
->
rcar_sound ec500000.sound: ssi[0] is connected to ssi[0]
~~~~~~ ~~~~~~
We still don't want to have pointless memory, so let's use ring buffer.
16byte x 5 is very enough for this purpose.
dev_xxx(dev, "%s is connected to %s\n",
rsnd_mod_name(mod_a), /* ssiu[00] */
rsnd_mod_name(mod_b)); /* ssi[0] */
->
rcar_sound ec500000.sound: ssiu[00] is connected to ssi[0]
