ASoC: rsnd: src: Avoid a potential deadlock
lockdep warns us that priv->lock and k->k_lock can cause a
deadlock when after acquire of k->k_lock, process is interrupted
by src, while in another routine of src .init, k->k_lock is
acquired with priv->lock held.

This patch avoids a potential deadlock by not calling soc_device_match()
in SRC .init callback, instead it adds new soc fields in priv->flags to
differentiate SoCs.

ASoC: rsnd: update BSDSR/BSDISR handling
Current BSDSR/BSDISR are using temporary/generic settings, but it can't
handle all SRCx/SoC. It needs to handle correctry.
Otherwise, sampling rate converted sound channel will be broken if it
was TDM. One note is that it needs to overwrite settings on E3 case.

ASoC: rsnd: handle DPCM converted rate/chan under core
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.

This patch move/merge SRC/CTU hw_param under core.c
and handles converted rate/chan under rsnd_dai_stream.

ASoC: rsnd: rsnd_mod_name() handles both name and ID
Current rsnd driver is using "%s[%d]" for mod name and ID,
but, this ID portion might confusable.
For example currently, CTU ID is 0 to 7, but using 00 to 13
(= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet.

In the future, we will support BUSIFn, but it will be more complicated
numbering. To avoid future confusable code, this patch modify
rsnd_mod_name() to return understandable name.

To avoid using pointless memory, it uses static char and snprintf,
thus, rsnd_mod_name() user should use it immediately, and shouldn't keep
its pointer.

ASoC: rsnd: move .get_status under rsnd_mod_ops
Each mod needs to have .get_status, but current driver is handling it

It is not any make sence. This patch moves it to rsnd_mod_ops, and
tidyup its parameter order to align to other callback functions.

Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

ASoC: rsnd: indicate IRQ error status for debug
SSI/SRC have under/over flow error handling, and its status is useful
for debuging. But sometimes it might be too much message,
and it might blocks necessity other information.

To avoid such situation, basically this patch indicates interrupt
status debug message if DEBUG was defined, but it will be suppressed
if RSND_DEBUG_NO_IRQ_STATUS was defined.

Sergei Shtylyov de1965159a rcar: src: skip disabled-SRC nodes
The current device tree representation of the R-Car Sample Rate Converters
(SRC) assumes that they are numbered consecutively, starting from 0. Alas,
this  is not  the case with the R8A7794 SoC where SRC0 isn't present.  In
order to keep the existing  device trees working, I'm suggesting to use a
disabled node for SRC0.  Teach the SRC probe  to just skip disabled nodes.

Kuninori Morimoto eed76bb811 ASoC: rsnd: add rsnd_runtime_channel_xxx()
Current SSI is supporting Normal SSI/Multi mode SSI/TDM mode SSI
and its behavior is based on input channels.
This input channel might be converted by CTU,
and SSI needs to be Multi SSI mode / TDM SSI mode if 6ch input

EX) 6ch input, CTU for 2ch, playback

 6ch    6ch    2ch    2ch    2ch     2ch
 -> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI

EX) 6ch input, no CTU, Multi SSI, playback

 6ch    6ch    6ch    6ch    6ch     2ch
 -> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI0/SSI1/SSI2

Current driver is using rsnd_get_adinr_chan() / rsnd_get_slot_width()
for this purpose, but it is complicated enough without meaning.
This patch adds new rsnd_runtime_channel_xxx() which is caring
CTU/Multi SSI.

Kuninori Morimoto 5ba17b42e1 ASoC: rsnd: each mod has status again for CTU/MUX support
SSI will be used as normal SSI or as clock parent SSI. Therefor,
rsnd driver wants to control SSI and parent SSI separately. Otherwise it
can't use Playback/Capture in the same time.
And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each
mod's status insted of rsnd_mod") before.

OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in
separately. Otherwise, these will be re-initialized during playing if
MUX merges 2 sounds.
Because of these picky reasons, this patch re-defines status on each mod,
and add new parent_ssi_status on rsnd_dai_stream.
