Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
dma-names on DT was implemented as no difference between 1st / 2nd
DMAC's, since rsnd had assumed that both DMACs are implemented as
DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented
as non DMAEngine, and it doesn't need dma-names anymore. So, this
dma-names rule is no longer needed.
And additionally, dma-names was assumed that it has all
(= SSI/SSIU/SRC/DVC) nodes under sound node.
In upstream code, no SoC/platform is supporting DMA for rsnd driver yet.
This means there is no compatible issue if this patch changes
dma-names's rule of DT.
This patch assumes dma-names for 1st DMAC are tx/rx base, and listed
in each SSI/SRC/DVC subnode
ex)
rcar_sound,dvc {
dvc0: dvc@0 {
dmas = <&audma0 0xbc>;
dma-names = "tx";
};
...
rcar_sound,src {
src0: src@0 {
...
dmas = <&audma0 0x85>, <&audma1 0x9a>;
dma-names = "rx", "tx";
};
...
rcar_sound,ssi {
ssi0: ssi@0 {
...
dmas = <&audma0 0x01>, <&audma1 0x02>, <&audma0 0x15>, <&audma1 0x16>;
dma-names = "rx", "tx", "rxu", "txu";
};

ASoC: rsnd: remove NULL check from rsnd_mod_name()/rsnd_mod_id()
Current rsnd driver has rsnd_mod_id() which returns mod ID,
and it returns -1 if mod was NULL.
In the same time, this driver has rsnd_mod_name() which returns mod
name, and it returns "unknown" if mod or mod->ops was NULL.
Basically these "mod" never be NULL, but the reason why rsnd driver
has such behavior is that DMA path finder is assuming memory as
"mod == NULL".
Thus, current DMA path debug code prints like below.
Here "unknown[-1]" means it was memory.
...
rcar_sound ec500000.sound: unknown[-1] from
rcar_sound ec500000.sound: src[0] to
rcar_sound ec500000.sound: ctu[2]
rcar_sound ec500000.sound: mix[0]
rcar_sound ec500000.sound: dvc[0]
rcar_sound ec500000.sound: ssi[0]
rcar_sound ec500000.sound: audmac[0] unknown[-1] -> src[0]
...
1st issue is that it is confusable for user.
2nd issue is rsnd driver has something like below code.
mask |= 1 << rsnd_mod_id(mod);
Because of this kind of code, some statically code checker will
reports "Shifting by a negative value is undefined behaviour".
But this "mod" never be NULL, thus negative shift never happen.
To avoid these issues, this patch adds new dummy "mem" to
indicate memory, and use it to indicate debug information,
and, remove unneeded "NULL mod" behavior from rsnd_mod_id() and
rsnd_mod_name().
The debug information will be like below by this patch
...
rcar_sound ec500000.sound: mem[0] from
rcar_sound ec500000.sound: src[0] to
rcar_sound ec500000.sound: ctu[2]
rcar_sound ec500000.sound: mix[0]
rcar_sound ec500000.sound: dvc[0]
rcar_sound ec500000.sound: ssi[0]
rcar_sound ec500000.sound: audmac[0] mem[0] -> src[0]

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: 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 */

ASoC: rsnd: add rsnd_adg_clk_query()
Current Renesas sound driver is assuming that all Sampling rate and
channles are possible to use, but these are depends on inputed clock
and SSI connection situation.
For example, if it is using 1 SSI, enabled TDM mode and has 12288000
input clock, 2ch output can support until 192000Hz, but 6ch output can
support until 64000Hz, 8ch can support 48000Hz.
To control these situation correctly, it needs to support
hw_constraints / refine feature.
To support such feature, it needs SSI clock query feature, and it needs
ADG clock query feature. Current ADG has rsnd_adg_ssi_clk_try_start()
and it is doing similar things, but it try to setup ADG register in
same time. This is not needed.
This patch adds new rsnd_adg_clk_query() and separates query feature
and register setting feature in adg.c

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 */
