A const prefix was put wrongly in the middle at the code refactoring
commit 932eaf7c79 ("ASoC: sh: siu_pcm: remove snd_pcm_ops"), which
leads to a build error as:
sound/soc/sh/siu_pcm.c:546:8: error: expected '{' before 'const'
Also, another inconsistency is that the declaration of siu_component
misses the const prefix.
This patch corrects both failures.

The tasklet is an old API that should be deprecated, usually can be
converted to another decent API. In ASoC SH SIU driver, a tasklet is
still used for offloading the hardware reset function. It can be
achieved gracefully with a work queued, too.
This patch replaces the tasklet usage in SH SIU driver with a simple
work. The conversion is fairly straightforward.

Fix the rsnd_ssi_stop function to skip disabling the individual SSIs of
a multi-SSI setup, as the actual stop is performed by rsnd_ssiu_stop_gen2
- the same logic as in rsnd_ssi_start. The attempt to disable these SSIs
was harmless, but caused a "status check failed" message to be printed
for every SSI in the multi-SSI setup.
The disabling of interrupts is still performed, as they are enabled for
all SSIs in rsnd_ssi_init, but care is taken to not accidentally set the
EN bit for an SSI where it was not set by rsnd_ssi_start.

The master SSI of a multi-SSI setup was attached both to the
RSND_MOD_SSI slot and the RSND_MOD_SSIP slot of the rsnd_dai_stream.
This is not correct wrt. the meaning of being "parent" in the rest of
the SSI code, where it seems to indicate an SSI that provides clock and
word sync but is not transmitting/receiving audio data.
Not treating the multi-SSI master as parent allows removal of various
special cases to the rsnd_ssi_is_parent conditions introduced in commit
a09fb3f28a ("ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode").
It also fixes the issue that operations performed via rsnd_dai_call()
were performed twice for the master SSI. This caused some "status check
failed" spam when stopping a multi-SSI stream as the driver attempted to
stop the master SSI twice.

The HDMI?_SEL register maps up to four stereo SSI data lanes onto the
sdata[0..3] inputs of the HDMI output block. The upper half of the
register contains four blocks of 4 bits, with the most significant
controlling the sdata3 line and the least significant the sdata0 line.
The shift calculation has an off-by-one error, causing the parent SSI to
be mapped to sdata3, the first multi-SSI child to sdata0 and so forth.
As the parent SSI transmits the stereo L/R channels, and the HDMI core
expects it on the sdata0 line, this causes no audio to be output when
playing stereo audio on a multichannel capable HDMI out, and
multichannel audio has permutated channels.
Fix the shift calculation to map the parent SSI to sdata0, the first
child to sdata1 etc.

As diffstat shows we've had again a lot of works done for this cycle:
majority of changes are the continued componentization and code
refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI;
some ioctls have been extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers;
the API itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers;
now including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers

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.

The current driver only sets 0x76543210 and 0x67452301 for DALIGN.
This doesn’t work well for TDM split and ex-split mode for all SSIU.
This patch programs the DALIGN registers based on the SSIU number.

According to R-Car3 HW manual 40.3.3 (Data Format on Audio Local Bus),
in case of monaural data writing or reading through Audio-DMAC,
it's always in Left Justified format, so both src and dst
DMA Bus width should be equal to physical data width.
Therefore set src and dst's DMA bus width to:
- [monaural case] data width
- [non-monaural case] 32bits (as prior applying the patch)

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.

ADG is using clk_get_rate() under atomic context, thus, we might
have scheduling issue.
To avoid this issue, we need to get/keep clk rate under
non atomic context.
We need to handle ADG as special device at Renesas Sound driver.
From SW point of view, we want to impletent it as
rsnd_mod_ops :: prepare, but it makes code just complicate.

Renesas sound device has many IPs and many situations.
If platform/board uses MIXer, situation will be more complex.
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 solve these issues, we need below.
To avoid card re-binding issue: check registered card->controls
To avoid duplicate DVC registration: check registered rsnd_kctrl_cfg
To allow multiple MIX registration: check registered rsnd_kctrl_cfg
This patch do it.

Current rsnd is using RSND_REG_xxx for register naming,
and using RSND_REG_##f style macro for read/write.
The biggest reason why it uses this style is that
we can avoid non-existing register access.
But, its demerit is sequential register access code will
be very ugly.
Current rsnd driver is well tested, so, let's remove RSND_REG_
from rsnd_reg, and cleanup sequential register access code.

commit c16015f36c ("ASoC: rsnd: add .get_id/.get_id_sub")
add new .get_id/.get_id_sub to indicate module ID/subID.
It is used for SSIU and CTU. In SSIU case, subID indicates BUSIF,
but register settings is based on SSIU ID.
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.

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")

- we can break loop if rsnd_dai_connect() was called

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] */
->

Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU.
Current driver is assuming it is using BUSIF0 as default.
Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach().
But, TDM split mode also needs other BUSIF to use it.
This patch adds missing SSIU BUSIFx support.
BUSIF is handled by SSIU instead of SSI anymore.
Thus, its settings no longer needed on SSI node on DT.
This patch removes its settings from Document, but driver is still
keeping compatibility. Thus, old DT style is still working.
But, to avoid confusing, it doesn't indicate old compatibility things on
Document. New SoC should have SSIU on DT from this patch.
1) old style DT is still supported (= no rcar_sound,ssiu node on DT)
2) If ssiu is not indicated on playback/capture,
BUSIF0 will be used as default
playback = <&ssi3>; /* ssiu30 will be selected */
3) you can select own ssiu
playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */

converted rate/chan are handled each rated module, but
it will be used other module too.
For examle, converted channel is currently used for CTU,
but, it will be used for TDM Split mode, too.
