ASoC: rsnd: adjust disabled module
In general Renesas SoC's SSI/SRC are all enabled, but some SoC is not.

	H2	E2

	SRC0	      <=
	SRC1	SRC1
	SRC2	SRC2
	...	...

Renesas Sound driver is assuming that *all* modules are
enabled, and thus it is using *data array* to access each modules.
Because of it, we have been using "status = disabled" at DT,
and using *full size* array but avoiding disabled module.

ex)
	rcar_sound,src {
		src-0 {
=>			status = "disabled";
		};
		src1: src-1 {
			...
		};
		...

But R-Car D3 have many disabled modules (It has SSI3/SSI4, SRC5/SRC6),
and Renesas SoC maintainer don't want above style on DT.

ex)
	rcar_sound,src {
=>		src0: src-0 { status = "disabled"; };
=>		src1: src-1 { status = "disabled"; };
=>		src2: src-2 { status = "disabled"; };
=>		src3: src-3 { status = "disabled"; };
=>		src4: src-4 { status = "disabled"; };
		src5: src-5 {
			...
		};
		src6: src-6 {
			...
		};
	};

	rcar_sound,ssi {
=>		ssi0: ssi-0 { status = "disabled"; };
=>		ssi1: ssi-1 { status = "disabled"; };
=>		ssi2: ssi-2 { status = "disabled"; };
		ssi3: ssi-3 {
			...
		};
		ssi4: ssi-4 {
			...
		};
	};

To adjust it, it needs to care about related for_each_child_of_node()
loop on rsnd driver, and it is used from...

	> grep -l for_each_child_of_node sound/soc/sh/rcar/*
	sound/soc/sh/rcar/core.c
	sound/soc/sh/rcar/ctu.c
	sound/soc/sh/rcar/dma.c
	sound/soc/sh/rcar/dvc.c
	sound/soc/sh/rcar/mix.c
	sound/soc/sh/rcar/src.c
	sound/soc/sh/rcar/ssi.c
	sound/soc/sh/rcar/ssiu.c

This patch adjust to this situation.
By this patch, we can avoid disabled modules on DT

	rcar_sound,src {
		src5: src-5 {
			...
		};
		src6: src-6 {
			...
		};
	};

	rcar_sound,ssi {
		ssi3: ssi-3 {
			...
		};
		ssi4: ssi-4 {
			...
		};
	};

ASoC: rsnd: protect mod->status
Renesas Sound uses many modules (SSI/SSIU/SRC/CTU/MIX/DVC/DMA),
and supports complex connections/path.
Thus each modules needs to save its status to correctly control it.
This status is updated when by .trigger, and .hw_params/.hw_free.

Renesas Sound is protecting modules by using lock when .trigger,
but it was not enough to protecting each modules "status" if it was
used from many paths.

1) .hw_params/.hw_free update status
2) another doesn't update status, but overwrites by same value

This patch do
1) protects .hw_params/.hw_free by lock
2) do nothing if no status update

Without this patch, protected mod->status (= .trigger) might be
overwrote by non protected mod->status (= .hw_params / .hw_free),
and in such case, CTU/MIX/DVC/SSIU/SSI which are used from
many paths might get damage.

If above issue happens, Renesas Sound will be hung (= silence)
and never be recoverd.
I could reproduce this issue by continue playing very short sound
with loop very long term (3-4 hours) through 2 inputs (= MIXer).

For updating rsnd_status_update(), this patch removes rsnd_dai_call()
debug message. Because we already have debugfs support, and is not
good match to new code.

ASoC: rsnd: core: Check convert rate in rsnd_hw_params
snd_pcm_hw_params_set_rate_near can return incorrect sample rate in
some cases, e.g. when the backend output rate is set to some value higher
than 48000 Hz and the input rate is 8000 Hz. So passing the value returned
by snd_pcm_hw_params_set_rate_near to snd_pcm_hw_params will result in
"FSO/FSI ratio error" and playing no audio at all while the userland
is not properly notified about the issue.

If SRC is unable to convert the requested sample rate to the sample rate
the backend is using, then the requested sample rate should be adjusted in
rsnd_hw_params. The userland will be notified about that change in the
returned hw_params structure.

75b1a8f9d6 ALSA: Convert strlcpy to strscpy when return value is unused
strlcpy is deprecated.  see: Documentation/process/deprecated.rst

Change the calls that do not use the strlcpy return value to the
preferred strscpy.

Done with cocci script:

@@
expression e1, e2, e3;
@@

-	strlcpy(
+	strscpy(
	e1, e2, e3);

This cocci script leaves the instances where the return value is
used unchanged.

After this patch, sound/ has 3 uses of strlcpy() that need to be
manually inspected for conversion and changed one day.

$ git grep -w strlcpy sound/
sound/usb/card.c:               len = strlcpy(card->longname, s, sizeof(card->longname));

sound/usb/mixer.c:                      return strlcpy(buf, p->names[index], buflen);

Miscellenea:

o Remove trailing whitespace in conversion of sound/core/hwdep.c

ASoC: soc-core: remove snd_soc_disconnect_sync()
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.

ASoC: rsnd: fix DALIGN register for SSIU
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.

ASoC: rsnd: Reinitialize bit clock inversion flag for every format setting
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.

It is pointless and confusable.

ASoC: rsnd: fixup MIX kctrl registration
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
registering method for rsnd_kctrl_new()") checks registered
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.

ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()
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")

ASoC: rsnd: add SSIU BUSIF support
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 */
