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.

Current rsnd_mod_call is counting its calling count to avoid unbalanced
function pair calling for error cases (ex init <-> quit).
SSI parent is now controlled as "mod" on current rsnd driver. Because of

SSI parent when user tried unbind. But probe/remove pair were not

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 355cb84fbe ASoC: rsnd: attach Audio-DMAC-periperi correctly
SSI/SRC will try to attach DMAC as Audio-DMAC or Audio-DMAC-periperi.
It is fixed IP, but will be attached to each streams as different module
in case of MUX (= multi sound path will be merged).
This patch solves this issue.

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.

Kuninori Morimoto 0719ecf7cb ASoC: rsnd: indicate register name for debug
Current rsnd driver is indicating how to use regmap debug method
on gen.c comment area.
regmap debug method indicates address and value, but rsnd driver is
using too many IPs (SSI/SSIU/SRC/CTU/MIX/DVC/CMD), and address.
Thus, we would like to know more useful information for debugging.
This patch indicates address name for debugging.

Arnd Bergmann e6e969f1fd ASoC: sh: fix fsi build warnings for 64 bit
As this driver can now be compiled for ARM64, we get a new warning
as a result of passing a DMA filter data pointer through an 'int':

sound/soc/sh/fsi.c: In function 'fsi_dma_probe':
sound/soc/sh/fsi.c:1372:24: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
     shdma_chan_filter, (void *)io->dma_id,

We already know that we only need the legacy filter function on
arch/sh, so we can hide the legacy DMA interface function
behind an #ifdef. This has the other advantage of no longer
depending on the shdma_chan_filter function to be visible.

Mengdong Lin 1a497983a5 ASoC: Change the PCM runtime array to a list
Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.

We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.

As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.

Later patches will further implement the DAI link list.

More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.

- traverse the rtd list to probe the link components and dais.

- Add a field "num" to PCM runtime struct, used to specify the device
  number when creating the pcm device, and for a soc card to access
  its dai_props array.

- The following 3rd party machine/platform drivers iterate the rtd list
  to check the runtimes:
  sound/soc/intel/atom/sst-mfld-platform-pcm.c
  sound/soc/intel/boards/cht_bsw_rt5645.c
  sound/soc/intel/boards/cht_bsw_rt5672.c

Renesas sound needs many devices
(SSI/SSIU/SRC/CTU/MIX/DVC/CMD/AudioDMAC/AudioDMACpp).
SSI/SRC/CTU/MIX/DVC are implemented as module.
SSI parent, SSIU are implemented as part of SSI
CMD is implemented as part of CTU/MIX/DVC
AudioDMAC/AudioDMACpp are implemented as part of SSI/SRC
It is nice sense that these all devices are implemented as mod.

Current rsnd_dma_of_path is assuming that all mods are related to DMA.
But it will be wrong. This patch tidyup this wrong assumption

Kuninori Morimoto 48d582819f ASoC: rsnd: remove all modules when PIO fallback
Current Renesas sound is supporting PIO fallback if it can't use DMA.
In such case, it should remove all attached modules, but current driver
is missing about CTU/MIX. Because current implement requests
specific mod for remove.
To avoid same things in future, this patch removes all mods,
and re-connects SSI when PIO fallback case.

not customer controlled module. These should be automatically install

each mod. SSI can be very special, because it will be installed as
SSI-parent / SSI-child. Thus, new rsnd_dai_connect() has type parameter
which should be mod->type except SSI-parent

Kuninori Morimoto 4362495734 ASoC: rsnd: Announce for removing Gen1 SRU support
Gen1 SRU support was created for preparation of Gen2 SRC support,
but no-one is using this feature (sampling rate convert) on Gen1.
BockW had used SRU before, but it was pass through mode.
This means it is same as SSI. And BockW "platform base" code was
removed from upstream code. It is now supported via DT, but it doesn't
use SRU. More detail, r8a7778.dtsi has "rcar_sound,src" entry, but
no-one is using this feature today. SRU probing has no relation to this
removing. This means there is no effect for DT compatibility, no issues
on upstream kernel.

Gen2 SRC was created from Gen1 SRU, these are similar but not same IP.
Keeping Gen1 SRU in current driver is a little bit difficult,
and no-one is using it today. Gen1 sound is still supported via SSI.
Gen1 SRU support will be removed in the next kernel version.
This patch announces it.

Kuninori Morimoto f1df122907 ASoC: rsnd: add common mod confirm method
Renesas sound has SSI/SRC/DVC/MIX/ADG modules, and these have original
register mapping. Thus this driver is using regmap field, and each module
is using it based on each module ID.

Sometimes, each module needs other module to controlling. but current each
function is using just "mod" as parameter name. This is confusable.
For example, if SSI0 and SRC2 are connected, and if SRC module function
has bug of module access, and if it needs to control connected SSI,
SRC function will access to SSI2 (It should access to SSI0, but it uses
SRC's ID 2). This is easy to happen in current driver style.

Add an intermediate cast to "uintptr_t" to kill the compile warning.

Lars-Peter Clausen e773c2f964 ASoC: rcar ctu: Staticise local symbols
rsnd_of_parse_ctu() is not used outside this file so it can be static.
Fixes the following sparse warning:

	sound/soc/sh/rcar/ctu.c:72:6: warning: symbol 'rsnd_of_parse_ctu' was
		not declared. Should it be static?

Kuninori Morimoto 70fb10529f ASoC: rsnd: add MIX (Mixer) support
This patch adds MIX (Mixer) initial support for rsnd driver.
It is assuming that this MIX is used via DPCM.

This is sample code for playback.

	CPU0  : [MEM] -> [SRC1] -> [CTU02] -+
					    |
					    +-> [MIX0] -> [DVC0] -> [SSI0]
	                                    |
	CPU1  : [MEM] -> [SRC2] -> [CTU03] -+

	sound {
		compatible = "renesas,rsrc-card";

		...

		cpu@0 {
			sound-dai = <&rcar_sound 0>;
		};

		cpu@1 {
			sound-dai = <&rcar_sound 1>;
		};

		codec {
			...
		};
	};

	rcar_sound {

		...

		rcar_sound,dai {
			dai0 {
				playback = <&src1 &ctu02 &mix0 &dvc0 &ssi0>;
			};
			dai1 {
				playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;
			};
		};
	};

Kuninori Morimoto 9269e3c3cf ASoC: rsnd: add CTU (Channel Transfer Unit) prototype support
This patch adds CTU (Channel Transfer Unit) support for rsnd driver.
But, it does nothing to data at this point, but is required for MIX
support.

CTU design is a little different from other IPs (CTU0 is including
CTU00 - CTU03, and CTU1 is including CTU10 - CTU13, these have different
register mapping) We need to care about it on this driver.

Kuninori Morimoto 7dfb491945 ASoC: rsnd: update Audio DMA path search method
Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri
are used from SSI/SSIU/SRC/DVC. But we will add CTU/MIX to this driver.
Then, current DMA path searching method is not understandable, and good
enough for this purpose. This patch update DMA path search method, more
simply.
