[PATCH 0/19] ASoC: rsnd: new module path method and DT support

[PATCH 0/19] ASoC: rsnd: new module path method and DT support

[Kuninori Morimoto]

Hi Mark

These are Renesas R-Car sound driver patches.
#1 - #7 are clean up patches.
#8 - #18 adds new module path method
#19 adds DT support

Now, Mark's ALSA branch doesn't include SH-ARM platform branch.
Thus, these patches are keeping compatible for it at this point.
Compatible code will be removed after merge.

Kuninori Morimoto (19):
       1) ASoC: rsnd: move priv member settings to upper side
       2) ASoC: rsnd: move rsnd_mod_call() macro
       3) ASoC: rsnd: remove verbose function parameter
       4) ASoC: rsnd: remove verbose debug message from scu/ssi
       5) ASoC: rsnd: unify rdai naming
       6) ASoC: rsnd: add .set_sysclk on snd_soc_dai_ops
       7) ASoC: rsnd: tidyup RSND_SSI_xxx flags
       8) ASoC: rsnd: run rsnd_path_init() when probe() timing
       9) ASoC: rsnd: use mod array instead of list on rdai
      10) ASoC: rsnd: get ssi/scu from rsnd_dai_stream
      11) ASoC: rsnd: add struct rsnd_dai_platform_info
      12) ASoC: rsnd: use function pointer for each probe
      13) ASoC: rsnd: Get correct SCU ID
      14) ASoC: rsnd: add rsnd_scu_enable_ssi_irq()
      15) ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSI
      16) ASoC: rsnd: add probe/remove callback on rsnd_mod_ops
      17) ASoC: rsnd: use mod probe method on SCU
      18) ASoC: rsnd: use mod probe method on SSI
      19) ASoC: rsnd: add DeviceTree support

[PATCH 06/19] ASoC: rsnd: add .set_sysclk on snd_soc_dai_ops

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

This patch adds struct snd_soc_dai_ops :: set_sysclk.
But, it do nothing, since rsnd sysclk is controlled by ADG.
Without this patch, simple-card init will be failed
if DT case.

We should fix the simple-card code so that it does not need this rather
than adding empty functions to all the drivers - I'd expect it to handle
-ENOTSUPP as not an error.

Ahh...

Current simple-card will get sysclk absolutely in normal (?) way.
Can you see end of asoc_simple_card_sub_parse_of() ?

rsnd got sysclk from it, but it is "module" clock, not "sysclk".

I guess I can avoid this issue if dtsi has

	system-clock-frequency = 0;

but it is strange.

Oops, I was misunderstanding.
I see, I will add -ENOTSUPP support.

[PATCH 08/19] ASoC: rsnd: run rsnd_path_init() when probe() timing

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rsnd SSIU/SSI/SCU/SRU path is set
when playback/capture starts up.
But it is meaningless method, since the path is based
on platform and can be set in probe() timing.
This patch sets the path on probe() timing.

This is fine but it depends on the set_sysclk() patch.

[PATCH 09/19] ASoC: rsnd: use mod array instead of list on rdai

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

struct rsnd_dai_stream used list for mod list.
It added only odd flexibility to current driver, and
it is a factor which makes extendibility difficult.
rsnd use mod array instead of list from now.

[PATCH 11/19] ASoC: rsnd: add struct rsnd_dai_platform_info

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

R-Car sound DAI consists from SSI/SCU/SSIU/SRU...
Current R-Car sound DAI is decided from these settings,
but it is intuitively unclear, and is not good design for DT support.
This patch adds new rsnd_dai_platform_info to solve this issue.

But now, many platform is using this driver without
rsnd_dai_platform_info.
So, this patch still supports DAI settings via SSI to keep compatible.
It will be removed in next Linux version.

[PATCH 13/19] ASoC: rsnd: Get correct SCU ID

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rsnd driver is assuming that SCU/SRU ID is
same as SSIU/SSI ID, because Gen1 can't select it.
But, Gen2 can select it.
The SCU/SRU/SSIU/SSI pair depends on the platform.
This patch get correct SCU ID from platform info.
To keep compatible, it still assuming SCU ID = SSI ID
if platform doesn't have info

[PATCH 14/19] ASoC: rsnd: add rsnd_scu_enable_ssi_irq()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current R-Car sound driver is assuming that
SCU mod is used even though it is not needed.
Because scu.c is controlling SSIU too.
(it is Gen1 compatibility)
But, SCU mod will be really not used if new platform dai
feature was used.
Thus, SSIU irq setting is called from SSI
directory by this patch.

[PATCH 16/19] ASoC: rsnd: add probe/remove callback on rsnd_mod_ops

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Each rsnd mod needs specific probe method,
and its best timing is DAI probe timing.
But current code runs it mod probe timing.
This patch adds new probe/remove callback to solve it.

Thank you for your help.
I tested these well. it can keep compatibility.
Thus, mark/topic/rcar is no problem I think.

But, can you please drop last [19/19] DT patch ?
I noticed not good point on this.

Sure, I'll skip it - still not read the full series yet anyway.

The ones I didn't comment on look broadly OK but there's dependencies on
earlier patches.

Re: [PATCH 0/19] ASoC: rsnd: new module path method and DT support

[Kuninori Morimoto]

Hi Mark

These are Renesas R-Car sound driver patches v2.
But I separated these into
 1) cleanup patches
 2) new feature patches

Because 1) + 2) becomes large number patches.
These are 1) part patches.
I will send 2) part patches if 1) are accepted

Kuninori Morimoto (8):

      ASoC: rsnd: use mod array instead of list on rdai
      ASoC: rsnd: get ssi/scu from rsnd_dai_stream

[PATCH 1/8] ASoC: rsnd: run rsnd_path_init() when probe() timing

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rsnd SSIU/SSI/SCU/SRU path is set
when playback/capture starts up.
But it is meaningless method, since the path is based
on platform and can be set in probe() timing.
This patch sets the path on probe() timing.

[PATCH 2/8] ASoC: rsnd: use mod array instead of list on rdai

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

struct rsnd_dai_stream used list for mod list.
It added only odd flexibility to current driver, and
it is a factor which makes extendibility difficult.
rsnd use mod array instead of list from now.

Re: [PATCH 0/19] ASoC: rsnd: new module path method and DT support

[Kuninori Morimoto]

Hi Mark

These are Renesas R-Car sound driver patches v2.

 1) cleanup patches
 2) new feature patches

These are 2) part patches.
#1, #2 patches add new style (= rsnd_dai_platform_info) to driver.
Current driver is still keeping compatible to old style,
but it will be removed after marge.
#10 is big patch, since it renames scu to src.
These #1, #2, and #10 are important for DT support

These are based on latest mark/topic/rcar

Kuninori Morimoto (11):
       1) ASoC: rsnd: add struct rsnd_dai_platform_info
       2) ASoC: rsnd: Get correct SCU ID
       3) ASoC: rsnd: add rsnd_scu_enable_ssi_irq()
       4) ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSI
       5) ASoC: rsnd: add probe/remove callback on rsnd_mod_ops
       6) ASoC: rsnd: use mod probe method on SCU
       7) ASoC: rsnd: use mod probe method on SSI
       8) ASoC: rsnd: nothing to do on rsnd_dai_remove()
       9) ASoC: rsnd: remove all rsnd_xxx_remove()
      10) ASoC: rsnd: rename scu to src
      11) ASoC: rsnd: add DeviceTree support

[PATCH 01/11] ASoC: rsnd: add struct rsnd_dai_platform_info

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

R-Car sound DAI consists from SSI/SCU/SSIU/SRU...
Current R-Car sound DAI is decided from these settings,
but it is intuitively unclear, and is not good design for DT support.
This patch adds new rsnd_dai_platform_info to solve this issue.

But now, many platform is using this driver without
rsnd_dai_platform_info.
So, this patch still supports DAI settings via SSI to keep compatible.
It will be removed in next Linux version.

[PATCH 02/11] ASoC: rsnd: Get correct SCU ID

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rsnd driver is assuming that SCU/SRU ID is
same as SSIU/SSI ID, because Gen1 can't select it.
But, Gen2 can select it.
The SCU/SRU/SSIU/SSI pair depends on the platform.
This patch get correct SCU ID from platform info.
To keep compatible, it still assuming SCU ID = SSI ID
if platform doesn't have info

[PATCH 03/11] ASoC: rsnd: add rsnd_scu_enable_ssi_irq()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current R-Car sound driver is assuming that
SCU mod is used even though it is not needed.
Because scu.c is controlling SSIU too.
(it is Gen1 compatibility)
But, SCU mod will be really not used if new platform dai
feature was used.
Thus, SSIU irq setting is called from SSI
directory by this patch.

[PATCH 04/11] ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSI

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current R-Car sound driver is assuming that
SCU mod is used even though it is not needed.
Because scu.c is controlling SSIU too.
(it is Gen1 compatibility)
But, SCU mod will be really not used if new platform dai
feature was added.
Thus, rsnd_scu_ssi_mode_init() is called from SSI
directory by this patch.

[PATCH 05/11] ASoC: rsnd: add probe/remove callback on rsnd_mod_ops

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Each rsnd mod needs specific probe method,
and its best timing is DAI probe timing.
But current code runs it mod probe timing.
This patch adds new probe/remove callback to solve it.

[PATCH 08/11] ASoC: rsnd: nothing to do on rsnd_dai_remove()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

rsnd_dai_remove() called rsnd_path_exit(),
but these memory will be cleaned automatically.
Because it is created by devm_kzalloc().
nothing to do on rsnd_dai_remove()

[PATCH 10/11] ASoC: rsnd: rename scu to src

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

R-Car sound has SCU unit which has SRC/CTU/MIX/DVC,
and current rsnd driver has scu.c and scu module.
Current scu.c has SRC support only.
My first concept was control these feature on scu.c
but, it become difficult and un-understandable now.
This patch rename scu to src

Does it mean it don't need "interrupt-parent" ?

So, I've applied this but it needs some improvement - please do that
incrementally.  One thing you should have done here is CC the binding to
the DT list and maintainers for review.

This needs clearer documentation saying what the subnodes are - they're
actually collections of further nodes, each of which represents
something in the hardware.  The examples are fairly clear but the text
needs more than just "subnode".  Someone should be able to tell how to
write the DT just given the datasheet and this document.

I see. will do
Thank you for your advice

I've merged the rcar branch that Mark Brown has pushed out, which has
all of these except #19 and have been trying to get it to work.

I am currently seeing issues where the CODEC fails to start, thus there
is no audio produced due to no audio bit or word clocks on the I2S bus
(the CODEC is the clock master).

Please show me more detail.
Are you using Lager board ? are you using DT ? or non-DT ?
It needs Mark's mark/topic/simple branch too.
Can you show me error log ?
