This series includes the following:
- new audio clock and reset controller data and adaptation for it of existing
code (patches 0001..0004);
- adaptation of existing audio components for A1 Soc (patches 0005..0021);
- handy cosmetics for dai-link naming (patches 0022..0023);
- integration of audio devices into common trees (patch 0024);
- audio support bring up on Amlogic ad402 reference board (patch 0025). This
patch is not actually checked on real hardware (because all ad402 that we had
were burned out). This patch is based on ad402's schematics and on experience
with our own hardware (which is very close to reference board);

Existing values were insufficient to produce accurate clock for audio
devices. New values are safe and most suitable to produce 48000Hz sample
rate.

The hifi pll is not about 48k only. I see no reason to restrict the PLL
to a single setting.
You've provided no justification why the PLL driver can't reach the same
setting for 48k. The setting below is just the crude part. the fine
tuning is done done with the frac parameter so I doubt this provides a
more accurate rate.

The hifi pll is not about 48k only. I see no reason to restrict the PLL
to a single setting.
You've provided no justification why the PLL driver can't reach the same
setting for 48k. The setting below is just the crude part. the fine
tuning is done done with the frac parameter so I doubt this provides a
more accurate rate.

You are right, it is not about 48k only. However, there are two issues.
First, indeed, I could just extend the range of multipliers to 1..255.
But I am unsure if hifi_pll is able to handle whole range of
mulptipliers. The value 128 is taken from Amlogic's branch, and I am
pretty sure that it works.
Second, unfortunately frac parameter currently doesn't work. When frac
is used enabling of hifi_pll fails in meson_clk_pll_wait_lock(). I see
it when try to use 44100Hz and multipliers' range is set to 1..255. So,
support of other rates than 48k requires extra effort.

Why 1..255 ? This is not what I'm pointing out
According to the datasheet - the range is 32 - 64, as currently
set in the driver.
The change you have provided request a multipler of 128/5 = 25,6
If you put assigned-rate = 614400000 in DT, I see no reason can find the
same solution on its own.

Then your change is even more problematic because it certainly does not
disable frac ... which you say is broken.
That parameter should be removed with a proper comment explaining why
you are disabling it. That type a limitation / known issue should be
mentionned in your change.

Could you point where in the doc the range 32..64 is documented?
Documentation that I have may be not so complete, but I don't see there
any mention about it.
Anyway, range 32..64 of multipliers is not enough to produce accurate
clock, and a need 128 for 48kHz.

The reasoning is following. I don't know why 32..64 range was declared
for this clock, and whether it would be safe to extend it and include
128, which is required for 48kHz. But I know, that multiplier=128 is
safe and works fine (together divider=5).

Handling of frac should not be removed, it should be fixed to achieve
another rates. But that is not the goal of this commit.

You have not answer my remark.
Mainline does not do everything like the AML SDK does. Saying you are
copying it because you know it works (in your opinion) is not good
enough.
I'm telling you that your hack is not necessary and so far, you have not
demonstrated that it is.
Also the multiplier range in m/n, not m alone.

You argued that frac was broken and that was partly why you introduced
this work around. I'm telling you this approach is incorrect.
So either :
* Remove frac for now, until it is fixed, because it is broken and add
comment clearly explaining that quirk.
* Or fix it now.
Your choice.

You argued that frac was broken and that was partly why you introduced
this work around. I'm telling you this approach is incorrect.
So either :
* Remove frac for now, until it is fixed, because it is broken and add
comment clearly explaining that quirk.
* Or fix it now.
Your choice.

You have not answer my remark.
Mainline does not do everything like the AML SDK does. Saying you are
copying it because you know it works (in your opinion) is not good
enough.
I'm telling you that your hack is not necessary and so far, you have not
demonstrated that it is.
Also the multiplier range in m/n, not m alone.

BTW, here Amlogic already mentioned all possible output audio rates for
which hifipll can be used:
https://lore.kernel.org/all/1569411888-98116-1-git-send-email-jian.hu@amlogic.com/T/#md7083b4f851ab97dfce43f8f6a3b266eb49ed329
```
The audio working frequency are 44.1khz, 48khz and 192khz.
614.4M can meet the three frequency.
after the hifi pll, there are two dividers in Audio clock.
614.4M/3200 = 192khz
614.4M/12800 = 48khz
614,4M/13932 = 44.0999khz
```

BTW, here Amlogic already mentioned all possible output audio rates for
which hifipll can be used:
https://lore.kernel.org/all/1569411888-98116-1-git-send-email-jian.hu@amlogic.com/T/#md7083b4f851ab97dfce43f8f6a3b266eb49ed329
```
The audio working frequency are 44.1khz, 48khz and 192khz.
614.4M can meet the three frequency.
after the hifi pll, there are two dividers in Audio clock.
614.4M/3200 = 192khz
614.4M/12800 = 48khz
614,4M/13932 = 44.0999khz
```

Thank you,

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

This controller provides clocks and reset functionality for audio
peripherals on Amlogic A1 SoC family.
The driver is almost identical to 'axg-audio', however it would be better
to keep it separate due to following reasons:
- significant amount of bits has another definition. I will bring there
a mess of new defines with A1_ suffixes.
- registers of this controller are located in two separate regions. It
will give a lot of complications for 'axg-audio' to support this.

All the above does essentially the same things as the macro of
axg-audio, to some minor differences. Yet it is another set to maintain.
I'd much prefer if you put the axg-audio macro in a header a re-used
those. There would a single set to maintain. You may then specialize the
included in the driver C file, to avoid redundant parameters
Rework axg-audio to use clk_parent_data if you must, but not in the same
series please.

Again, I'm not a fan of this many levels of macro. I can live with it
but certainly don't want the burden of reviewing and maintaining for
clock driver. AXG / G12 and A1 are obviously closely related, so make it common.

That is overengineered. Please keep it simple. Declare the regmap_config
as static const global, and do it like axg-audio please.

No - Looks to me you just have two clock controllers you are trying
force into one.

Again, this shows 2 devices. The one related to your 'map0' should
request AUD2_CLKID_AUDIOTOP as input and enable it right away.

That is seriouly overengineered.
The following are offset. Just write what they are.
There is not reason to put that into a header. It is only going to be
used by a single driver.

Does not help readeability. Just pass the flag as axg-audio does.

All the above does essentially the same things as the macro of
axg-audio, to some minor differences. Yet it is another set to maintain.
I'd much prefer if you put the axg-audio macro in a header a re-used
those. There would a single set to maintain. You may then specialize the
included in the driver C file, to avoid redundant parameters
Rework axg-audio to use clk_parent_data if you must, but not in the same
series please.

Again, I'm not a fan of this many levels of macro. I can live with it
but certainly don't want the burden of reviewing and maintaining for
clock driver. AXG / G12 and A1 are obviously closely related, so make it common.

That is overengineered. Please keep it simple. Declare the regmap_config
as static const global, and do it like axg-audio please.

No - Looks to me you just have two clock controllers you are trying
force into one.

Again, this shows 2 devices. The one related to your 'map0' should
request AUD2_CLKID_AUDIOTOP as input and enable it right away.

That is seriouly overengineered.
The following are offset. Just write what they are.
There is not reason to put that into a header. It is only going to be
used by a single driver.

Does not help readeability. Just pass the flag as axg-audio does.

All the above does essentially the same things as the macro of
axg-audio, to some minor differences. Yet it is another set to maintain.
I'd much prefer if you put the axg-audio macro in a header a re-used
those. There would a single set to maintain. You may then specialize the
included in the driver C file, to avoid redundant parameters
Rework axg-audio to use clk_parent_data if you must, but not in the same
series please.

Again, I'm not a fan of this many levels of macro. I can live with it
but certainly don't want the burden of reviewing and maintaining for
clock driver. AXG / G12 and A1 are obviously closely related, so make it common.

That is overengineered. Please keep it simple. Declare the regmap_config
as static const global, and do it like axg-audio please.

No - Looks to me you just have two clock controllers you are trying

Again, this shows 2 devices. The one related to your 'map0' should
request AUD2_CLKID_AUDIOTOP as input and enable it right away.

That is seriouly overengineered.
The following are offset. Just write what they are.
There is not reason to put that into a header. It is only going to be
used by a single driver.

Most of fishy workarounds that you commented is caused the fact the mmio
of this clock controller is divided into two parts. Compare it with
axg-audio driver, things that was part of contigous memory region (like
pdm) here are moved to second region. Is this enough to make a guess
that these are two devices?
Concerning AUD2_CLKID_AUDIOTOP clock, as it turned out, it must be
enabled before enabling of clocks from second region too. That is
AUD2_CLKID_AUDIOTOP clock feeds both parts of this clock controller.

Except one thing... Here I keep memory identifier to which this clock
belongs:
.map = AUDIO_REG_MAP(_reg),
It is workaround, but ->map the only common field in clk_regmap that
could be used for this purpose.

This only reason why it is not "static const" because I need to set

Most of fishy workarounds that you commented is caused the fact the mmio
of this clock controller is divided into two parts. Compare it with
axg-audio driver, things that was part of contigous memory region (like
pdm) here are moved to second region. Is this enough to make a guess
that these are two devices?
Concerning AUD2_CLKID_AUDIOTOP clock, as it turned out, it must be
enabled before enabling of clocks from second region too. That is
AUD2_CLKID_AUDIOTOP clock feeds both parts of this clock controller.

Except one thing... Here I keep memory identifier to which this clock
belongs:
.map = AUDIO_REG_MAP(_reg),
It is workaround, but ->map the only common field in clk_regmap that
could be used for this purpose.

This implementation uses two regmaps, and this field allow to avoid

This only reason why it is not "static const" because I need to set

This is all in order to keep range's identifier together with offset and

Most of fishy workarounds that you commented is caused the fact the mmio
of this clock controller is divided into two parts. Compare it with
axg-audio driver, things that was part of contigous memory region (like
pdm) here are moved to second region. Is this enough to make a guess
that these are two devices?
Concerning AUD2_CLKID_AUDIOTOP clock, as it turned out, it must be
enabled before enabling of clocks from second region too. That is
AUD2_CLKID_AUDIOTOP clock feeds both parts of this clock controller.

Except one thing... Here I keep memory identifier to which this clock
belongs:
.map = AUDIO_REG_MAP(_reg),
It is workaround, but ->map the only common field in clk_regmap that
could be used for this purpose.

I see obsolutely no reason to think it is a single device nor to add all the quirks
you have the way you did. So yes, in that case, 2 zones, 2 devices.

Yes. I understood the first time around and already commented on that.

I see obsolutely no reason to think it is a single device nor to add all the quirks
you have the way you did. So yes, in that case, 2 zones, 2 devices.

Yes. I understood the first time around and already commented on that.

Yes. I understood the first time around and already commented on that.

Jerome, I have reworked my driver reusing axg-audio code as most as I
could and now I have one more question. Lets see on this definition from
axg-audio:
#define AUD_MST_MUX(_name, _reg, _flag) \
AUD_MUX(_name##_sel, _reg, 0x7, 24, _flag, \
mst_mux_parent_data, 0)
#define AUD_MST_MCLK_MUX(_name, _reg) \
AUD_MST_MUX(_name, _reg, CLK_MUX_ROUND_CLOSEST)
CLK_SET_RATE_PARENT is not set here. But why? It means, that topmost pll
clock will not be reconfigured at runtime to satisfy the rate that was
requested from axg-tdm.

Jerome, I have reworked my driver reusing axg-audio code as most as I
could and now I have one more question. Lets see on this definition from
axg-audio:
#define AUD_MST_MUX(_name, _reg, _flag) \
AUD_MUX(_name##_sel, _reg, 0x7, 24, _flag, \
mst_mux_parent_data, 0)
#define AUD_MST_MCLK_MUX(_name, _reg) \
AUD_MST_MUX(_name, _reg, CLK_MUX_ROUND_CLOSEST)
CLK_SET_RATE_PARENT is not set here. But why? It means, that topmost pll
clock will not be reconfigured at runtime to satisfy the rate that was
requested from axg-tdm.

Jerome, I have reworked my driver reusing axg-audio code as most as I
could and now I have one more question. Lets see on this definition from
axg-audio:
#define AUD_MST_MUX(_name, _reg, _flag) \
AUD_MUX(_name##_sel, _reg, 0x7, 24, _flag, \
mst_mux_parent_data, 0)
#define AUD_MST_MCLK_MUX(_name, _reg) \
AUD_MST_MUX(_name, _reg, CLK_MUX_ROUND_CLOSEST)
CLK_SET_RATE_PARENT is not set here. But why? It means, that topmost pll
clock will not be reconfigured at runtime to satisfy the rate that was
requested from axg-tdm.

Yes, that is by design. It is another area where mainline audio differs
greatly from AML vendor code. The PLLs are expected be to fixed and the
audio master clock will reparent to the most adequate PLL source
depending on the use case.
This is how we manage to satisfy all audio interfaces with a very
limited number of PLLs
On AXG/G12 there is at most 6 concurrent interfaces (3 FRDDR/TODDR) - 8
on sm1 - and we can satisfy on that with 3 PLLs. That would not be
possible if interfaces were having their way with the PLLs, reseting it
everytime a stream is started.
The PLL rate should be carefully chosen so it can be derived easily. On
AXG/G12/SM1 that is:
* one PLL per rate family, to maximize clock precision
* x24 x32: to handle different sample sizes
* x2 until we reach the PLL limits to allow higher rates such as 384kHz
or even higher
If you have less PLLs on A1, you'll have to make compromises, like a less
precise clock to support multiple family with one PLL.
This is why the PLLs are set for each platform in DT because that choice
may depend on the platform use case.

Yes, that is by design. It is another area where mainline audio differs
greatly from AML vendor code. The PLLs are expected be to fixed and the
audio master clock will reparent to the most adequate PLL source
depending on the use case.
This is how we manage to satisfy all audio interfaces with a very
limited number of PLLs
On AXG/G12 there is at most 6 concurrent interfaces (3 FRDDR/TODDR) - 8
on sm1 - and we can satisfy on that with 3 PLLs. That would not be
possible if interfaces were having their way with the PLLs, reseting it
everytime a stream is started.
The PLL rate should be carefully chosen so it can be derived easily. On
AXG/G12/SM1 that is:
* one PLL per rate family, to maximize clock precision
* x24 x32: to handle different sample sizes
* x2 until we reach the PLL limits to allow higher rates such as 384kHz
or even higher
If you have less PLLs on A1, you'll have to make compromises, like a less
precise clock to support multiple family with one PLL.
This is why the PLLs are set for each platform in DT because that choice
may depend on the platform use case.

Yes, that is by design. It is another area where mainline audio differs
greatly from AML vendor code. The PLLs are expected be to fixed and the
audio master clock will reparent to the most adequate PLL source
depending on the use case.
This is how we manage to satisfy all audio interfaces with a very
limited number of PLLs
On AXG/G12 there is at most 6 concurrent interfaces (3 FRDDR/TODDR) - 8
on sm1 - and we can satisfy on that with 3 PLLs. That would not be
possible if interfaces were having their way with the PLLs, reseting it
everytime a stream is started.
The PLL rate should be carefully chosen so it can be derived easily. On
AXG/G12/SM1 that is:
* one PLL per rate family, to maximize clock precision
* x24 x32: to handle different sample sizes
* x2 until we reach the PLL limits to allow higher rates such as 384kHz
or even higher
If you have less PLLs on A1, you'll have to make compromises, like a less
precise clock to support multiple family with one PLL.
This is why the PLLs are set for each platform in DT because that choice
may depend on the platform use case.

Thank you. Now it has become much clearer.

Unfortunately, on A1 we have only one PLL.
Yes, for us it would be better to have hifi_pll with predefined rate.
For instance it will allow to avoid that ugly workaround in PDM (sysrate
property, etc).
But what whould be preferred for upstream? I can imagine a scenario
where samples with different rate should be played, PDM attached to
fclk_divN and there are no conflicts with TDM. In this case
reconfiguration of hifi_pll on demand could better satisfy somebody's
requirements.

Thank you. Now it has become much clearer.

Unfortunately, on A1 we have only one PLL.
Yes, for us it would be better to have hifi_pll with predefined rate.
For instance it will allow to avoid that ugly workaround in PDM (sysrate
property, etc).
But what whould be preferred for upstream? I can imagine a scenario
where samples with different rate should be played, PDM attached to
fclk_divN and there are no conflicts with TDM. In this case
reconfiguration of hifi_pll on demand could better satisfy somebody's
requirements.

Thank you. Now it has become much clearer.

Unfortunately, on A1 we have only one PLL.
Yes, for us it would be better to have hifi_pll with predefined rate.
For instance it will allow to avoid that ugly workaround in PDM (sysrate
property, etc).
But what whould be preferred for upstream? I can imagine a scenario
where samples with different rate should be played, PDM attached to
fclk_divN and there are no conflicts with TDM. In this case
reconfiguration of hifi_pll on demand could better satisfy somebody's
requirements.

That where compromises comes in. Pick a rate known as 'audio friendly'
which match some rates and appromixate others, or use codec clock master.

That is another problem entirely.
Krzysztof and I already covered what you should do for this.
The exact rate the PDM system clock does not matter at all because the
driver queries the actual rate of the clocks and adapts.
You have problems here only because you added CLK_SET_RATE_PARENT and
you are triggering the concurrent usage problem I explain below.

You are considering only PDM and 1 TDM. The SoC has 2 TDMs which could
be active concurrently a different rates.

No this is not possible. Doing so does not allow all the interfaces to be
used concurrently.
* If the PLL is not protected, existing streams get broken by new
starting stream when the PLL is reconfigured
* If the PLL is protected, new stream effectively starve because no
clock may provide a 'good enough' rate for them
This is why the reference rate must carefully chosen, something CCF
cannot do for you.
For example, a source of 12.288MHz (and its powers of 2) allows to match
48 and 32kHz sample rates and approximate 44.1kHz rates with an
acceptable drift.

That where compromises comes in. Pick a rate known as 'audio friendly'
which match some rates and appromixate others, or use codec clock master.

That is another problem entirely.
Krzysztof and I already covered what you should do for this.
The exact rate the PDM system clock does not matter at all because the
driver queries the actual rate of the clocks and adapts.
You have problems here only because you added CLK_SET_RATE_PARENT and
you are triggering the concurrent usage problem I explain below.

You are considering only PDM and 1 TDM. The SoC has 2 TDMs which could
be active concurrently a different rates.

No this is not possible. Doing so does not allow all the interfaces to be
used concurrently.
* If the PLL is not protected, existing streams get broken by new
starting stream when the PLL is reconfigured
* If the PLL is protected, new stream effectively starve because no
clock may provide a 'good enough' rate for them
This is why the reference rate must carefully chosen, something CCF
cannot do for you.
For example, a source of 12.288MHz (and its powers of 2) allows to match
48 and 32kHz sample rates and approximate 44.1kHz rates with an
acceptable drift.

That where compromises comes in. Pick a rate known as 'audio friendly'
which match some rates and appromixate others, or use codec clock master.

That is another problem entirely.
Krzysztof and I already covered what you should do for this.
The exact rate the PDM system clock does not matter at all because the
driver queries the actual rate of the clocks and adapts.
You have problems here only because you added CLK_SET_RATE_PARENT and
you are triggering the concurrent usage problem I explain below.

You are considering only PDM and 1 TDM. The SoC has 2 TDMs which could
be active concurrently a different rates.

No this is not possible. Doing so does not allow all the interfaces to be
used concurrently.
* If the PLL is not protected, existing streams get broken by new
starting stream when the PLL is reconfigured
* If the PLL is protected, new stream effectively starve because no
clock may provide a 'good enough' rate for them
This is why the reference rate must carefully chosen, something CCF
cannot do for you.
For example, a source of 12.288MHz (and its powers of 2) allows to match
48 and 32kHz sample rates and approximate 44.1kHz rates with an
acceptable drift.

---- >8 ----
Hope, I haven't misinterpreted the terminology and codec-glue's behavior
too much.
---- >8 ----
The glue saves stream's private data in front-end dai and then backend
dai can reach them searching backward from sink to source. For capture
stream everything left the same, but searching should be performed from
source to sink.

---- >8 ----
Hope, I haven't misinterpreted the terminology and codec-glue's behavior
too much.
---- >8 ----
The glue saves stream's private data in front-end dai and then backend
dai can reach them searching backward from sink to source. For capture
stream everything left the same, but searching should be performed from
source to sink.

---- >8 ----
Hope, I haven't misinterpreted the terminology and codec-glue's behavior
too much.
---- >8 ----
The glue saves stream's private data in front-end dai and then backend
dai can reach them searching backward from sink to source. For capture
stream everything left the same, but searching should be performed from
source to sink.

For both G12A and SM1 the width of "Lane Select" should be 2, not 3.
Otherwise, it overlaps with "Source".

Missing a Fixes tag.
Ideally fixes should be sent first in a series - or even separately in
this case

Missing a Fixes tag.
Ideally fixes should be sent first in a series - or even separately in
this case

When you resend this, could you describe how this bug might look to a
user? If a user hits this bug and they want to see if it has been
fixed by reading the commit messages, I don't think this description
is sufficient for that.

Sorry, I screwed up. Original code is correct. I mixed up the maximum
value and bit offset.

There is a lot of defines, but almost all of them are not used. Lets
rework them:
- keep separate the definition for different platforms to make easier
checking that they match documentation.
- use LSB/MSB sufixes for uniformity.
- don't use hard-coded values for already declared defines.

There is a lot of defines, but almost all of them are not used. Lets
rework them:
- keep separate the definition for different platforms to make easier
checking that they match documentation.
- use LSB/MSB sufixes for uniformity.
- don't use hard-coded values for already declared defines.

I don't understand the second part. You did not add any options, no
phandles. You added some defines for something, so say what are these
"something".

I mean the following... This commit adds new defines to
meson-g12a-toacodec.h header. These defines are used in the following way:
sound-dai = <&toacodec TOACODEC_IN_A>;
sound-dai = <&toacodec TOACODEC_CAPTURE_OUT_A>;
So, can you make an advise how to call something like "&toacodec" to
which I declare new parameters.

&toacodec is phandle but it is not really relevant here. You should
explain what these defines are. DAI ids?

Internal codec on A1 SoC has ADC and this commit adds support for
capturing from it.
Also, regmap now uses caching for all platforms. Values that are written
to toacodec's register on A1 SoC can not be read back, that breaks
regmap_update_bits() functionality. Let's hope the caching will not
break anything on other platforms.

Cc: kernel
Internal codec on A1 SoC has ADC and this commit adds support for
capturing from it.
Also, regmap now uses caching for all platforms. Values that are written
to toacodec's register on A1 SoC can not be read back, that breaks
regmap_update_bits() functionality. Let's hope the caching will not
break anything on other platforms.

If the maximum register is 0 how does the regmap have a stride?

reg_stride inherited from existing code. Apparently, it was meaningless
even before my modifications (the hardware has single register
regardless of max_register declaration) and it should be dropped. But,
is it okay to remove it in the same commit?

Yes it has a single register, for now. Still the stride is 4.
And assuming the mmio region passed from DT is correct, I'm not sure the
hunk is useful at all.

Why would this be varied at runtime rather than being something fixed

Yes, I could use SND_SOC_DAPM_SUPPLY, but it supports only raw values,
and doesn't supports enums. Here, I want to use enum to restrict
possible values, because only these values mentioned in the
documentation that I have.

A supply is an on/off switch not an enum. Users should not be selecting
values at all.

Ok. For me it is great if I am free to move these kcontrols to device tree.

This is mis-leading.
It does not look like the change is A1 specific but rather a extension
of the support for t9015. It also mixes several different topics like line
configuration, capture support, etc ...
Again, the t9015 changes should be a separated series from the rest, and
there should be one patch per topic.
As Mark, if something is meant to be configured based on the HW layout,
then there a good change a kcontrol is not appropriate, and this should
rather be part of the platform description, like DT.
It was also suggested here:

This is mis-leading.
It does not look like the change is A1 specific but rather a extension
of the support for t9015. It also mixes several different topics like line
configuration, capture support, etc ...
Again, the t9015 changes should be a separated series from the rest, and
there should be one patch per topic.
As Mark, if something is meant to be configured based on the HW layout,
then there a good change a kcontrol is not appropriate, and this should
rather be part of the platform description, like DT.
It was also suggested here:

First, it is not only extentsion. Some bits are changed comparing to
existing t9015, so new compatible string is still required.
Second, I don't know anything about about ADC in t9015 on other SoCs and
even don't sure that it exist there (may be I am inattentive, but I'm
unable to find audio input pin on sm1/g12a's pinout).

Ok. By the way, on a1 LINEOUT_CFG would have another value.

First, it is not only extentsion. Some bits are changed comparing to
existing t9015, so new compatible string is still required.
Second, I don't know anything about about ADC in t9015 on other SoCs and
even don't sure that it exist there (may be I am inattentive, but I'm
unable to find audio input pin on sm1/g12a's pinout).

Ok. By the way, on a1 LINEOUT_CFG would have another value.

First, it is not only extentsion. Some bits are changed comparing to
existing t9015, so new compatible string is still required.
Second, I don't know anything about about ADC in t9015 on other SoCs and
even don't sure that it exist there (may be I am inattentive, but I'm
unable to find audio input pin on sm1/g12a's pinout).

Ok. By the way, on a1 LINEOUT_CFG would have another value.

No vendor prefix, so is it a generic property? Also, missing unit
suffix, but more importantly I don't understand why this is a property
of hardware.

+1.
The appropriate way to set rate of the clock before the driver take over
is 'assigned-rate', if you need to customize this for different
platform.
Then you don't have to deal with it in the device driver.

It would be great, but it doesn't work. Below, is what I want to see:
assigned-clocks =
<&clkc_audio AUD2_CLKID_PDM_SYSCLK_SEL>,
<&clkc_audio AUD2_CLKID_PDM_SYSCLK_DIV>;
assigned-clock-parents =
<&clkc_pll CLKID_FCLK_DIV3>,
<0>;
assigned-clock-rates =
<0>,
<256000000>;
But regardles of this declaration, PDM's driver unconditionally sets
sysclk'rate to 250MHz and throws away everything that was configured
before, reparents audio2_pdm_sysclk_mux to hifi_pll and changes
hifi_pll's rate.
This value 250MHz is declared here:
static const struct axg_pdm_cfg axg_pdm_config = {
.filters = &axg_default_filters,
.sys_rate = 250000000,
};
The property 'sysrate' is intended to redefine hardcoded 'sys_rate'
value in 'axg_pdm_config'.

It would be great, but it doesn't work. Below, is what I want to see:
assigned-clocks =
<&clkc_audio AUD2_CLKID_PDM_SYSCLK_SEL>,
<&clkc_audio AUD2_CLKID_PDM_SYSCLK_DIV>;
assigned-clock-parents =
<&clkc_pll CLKID_FCLK_DIV3>,
<0>;
assigned-clock-rates =
<0>,
<256000000>;
But regardles of this declaration, PDM's driver unconditionally sets
sysclk'rate to 250MHz and throws away everything that was configured
before, reparents audio2_pdm_sysclk_mux to hifi_pll and changes
hifi_pll's rate.
This value 250MHz is declared here:
static const struct axg_pdm_cfg axg_pdm_config = {
.filters = &axg_default_filters,
.sys_rate = 250000000,
};
The property 'sysrate' is intended to redefine hardcoded 'sys_rate'
value in 'axg_pdm_config'.

What is stopping you from removing that from the driver and adding
assigned-rate to 250M is the existing platform ?

... Also, considering how PDM does work, I'm not sure I get the point of
the doing all this to go from 250MHz to 256Mhz.
PDM value is sampled at ~75% of the half period. That clock basically
feeds a counter and the threshold is adjusted based on the clock rate.
So there is no need to change the rate. Changing it is only necessary
when the captured audio rate is extremely slow (<8kHz) and the counter
may overflow. The driver already adjust this automatically.
So changing the input rate from 250MHz to 256MHz should not make any
difference.

... Also, considering how PDM does work, I'm not sure I get the point of
the doing all this to go from 250MHz to 256Mhz.
PDM value is sampled at ~75% of the half period. That clock basically
feeds a counter and the threshold is adjusted based on the clock rate.
So there is no need to change the rate. Changing it is only necessary
when the captured audio rate is extremely slow (<8kHz) and the counter
may overflow. The driver already adjust this automatically.
So changing the input rate from 250MHz to 256MHz should not make any
difference.

The point is to use fclk_div3 clock as source for PDM's sysclock and
keep hiff_pll clock free for TDM. Because, I can get 256MHz from any
hifi_pll and fclk_div3, but only hifi_pll is able to provide accurate
48kHz (after several divider).

That's driver's problem. You do not change bindings, just because your
driver behaves differently. Just fix driver.

What does it have to do with bindings? Change driver if you are not
happy how it operates.

What do you mean? I am adding some new property and should describe it

No, if the property is not suitable for bindings, you should not add it
in the first place. So again: explain what sort of hardware, not driver,
problem you are solving here, so we can understand why do you need new
property. Otherwise use existing properties or no properties, because we
do not define all possible clocks in the bindings.
Let's be clear: with such commit msg explanation as you have, my answer
is: no, driver should set clock frequency and you do not need this
property at all.
Best regards,
Krzysztof

Could you please take a look on answer to "Jerome Brunet
<jbrunet@baylibre.com>"'s message on the same thread. There, I am trying
to explain what I am solving by this commit.
I would be happy to avoid this w/a, but currently this is the best I
came up with.

How is this answer here? You asked "What do you mean", so apparently you
did not understand why I am responding and why you cannot just document
whatever you wish, because that "whatever you wish" is not correct. I
explained that but now you respond that I should read other part of
emails. Really?
So again, do you understand that commit msg should provide rationale why
you think this describes hardware and why this is suitable for bindings?
Best regards,
Krzysztof

This driver unconditionally set the rate of DSP system clock to 250MHz,
that on A1 SoC family causes reconfiguring of 'hifi_pll' clock to some
rate, that is multiple to 250MHz.
Further, when playback is activating 'hifi_pll' would be reconfigured
to another rate to produce audio clock like 12288000Hz. Both these rates
can't coexist on same parent.
To avoid the fight for 'hifi_pll' clock allow PDM controller to
configure its maximum sysrate through device tree. It will allow to
inherit 'sysclk' from another clock (i.e. 'fclk_div2') and isolate
'hifi_pll' from PDM influence.

I know the rule about SoC related name but it is different here.
This does not describe HW in the SoC.
The axg sound card is just a name, much like simple-card or
audio-graph-card. I could have named it "amlogic,my-awesome-card"
We would not add "amlogic,a1-simple-card", would we ?
It is purely a software component, which aggregate HW ones.

Same as the card driver. I could have named it "amlogic,tdm-iface"
This is purely a SW component, which help agregate clocks and
tdm-formatters. It is analog to a "gpio-leds" or a "pwm-clock"
driver. We would add a compatible for every SoC for these, would we ?
I don't think it makes a lot of sense to add this. It is not going to
hurt but this is just adding useless compatible to the doc that will
never be used

The 'link-name' property is an optional DT property that allows for the
customization of the name associated with the DAI link and PCM stream.
This functionality mirrors the approach commonly utilized in Qualcomm
audio cards, providing flexibility in DAI naming conventions for
improved system integration and userspace experience.
It allows userspace program to easy determine PCM stream purpose, e.g.:
~ # cat /proc/asound/pcm
00-00: speaker (*) : : playback 1
00-01: mics (*) : : capture 1
00-02: loopback (*) : : capture 1

The 'link-name' property presents an optional DT feature that empowers
users to customize the name associated with the DAI link and PCM stream.
This functionality reflects the approach often employed in Qualcomm
audio cards, providing enhanced flexibility in DAI naming conventions
for improved system integration and userspace experience.
It allows userspace program to easy determine PCM stream purpose, e.g.:
~ # cat /proc/asound/pcm
00-00: speaker (*) : : playback 1
00-01: mics (*) : : capture 1
00-02: loopback (*) : : capture 1
The previous naming approach using auto-generated fe or be strings
continues to be utilized as a fallback.

The 'link-name' property presents an optional DT feature that empowers
users to customize the name associated with the DAI link and PCM stream.
This functionality reflects the approach often employed in Qualcomm
audio cards, providing enhanced flexibility in DAI naming conventions
for improved system integration and userspace experience.
It allows userspace program to easy determine PCM stream purpose, e.g.:
~ # cat /proc/asound/pcm
00-00: speaker (*) : : playback 1
00-01: mics (*) : : capture 1
00-02: loopback (*) : : capture 1
The previous naming approach using auto-generated fe or be strings
continues to be utilized as a fallback.

This commit adds the declarartion of currently supported audio devices
and their pins found Amlog A1 SoC family. SPDIF declaration is missing
here becase there are no publicly available boards with it.

I'm sorry but a 25 patches series is just way too big, especially when
spamming multiple sub systems.
Please try to make one series per sub systems and general topic, I see
at least
* A1 audio clocks
* G12 acodec fix
* Acodec rework
* PDM
* pinctrl
* arm64
I did not review all but I think I've made enough comments to keep you
busy for a while

I'm sorry but a 25 patches series is just way too big, especially when
spamming multiple sub systems.
Please try to make one series per sub systems and general topic, I see
at least
* A1 audio clocks
* G12 acodec fix
* Acodec rework
* PDM
* pinctrl
* arm64
I did not review all but I think I've made enough comments to keep you
busy for a while

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
New warnings running 'make CHECK_DTBS=y amlogic/meson-a1-ad402.dtb' for 20240314232201.2102178-1-jan.dakinevich@salutedevices.com:

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade

Thanks for your serie, it's nice you're working on upstreaming this feature.
In my opinion it's fine to have a "big" initial serie if you're not sure
if your changes are ok, but next time add the RFC tag so we know it's not
a final changeset and you seek advices.
Overall the code is clean and your patch order makes sense if they were meant
to be applied by a single maintainer, but in this case it will be split
into multiple subsystems so it's better to split them as Jerome explained
to ease review and the maintainers process.
Don't hesitate discussing with us in the #linux-amlogic IRC channel
on Libera.Chat, the goal is to reduce the number of patch version and
ease the review and maintainance process.
Concerning the link-name property, I think it should be done afterwards
since it's not necessary to support audio on A1, and I think it could
be extended to other SoC boards (which would be a great feature).

Thanks for your serie, it's nice you're working on upstreaming this feature.
In my opinion it's fine to have a "big" initial serie if you're not sure
if your changes are ok, but next time add the RFC tag so we know it's not
a final changeset and you seek advices.
Overall the code is clean and your patch order makes sense if they were meant
to be applied by a single maintainer, but in this case it will be split
into multiple subsystems so it's better to split them as Jerome explained
to ease review and the maintainers process.
Don't hesitate discussing with us in the #linux-amlogic IRC channel
on Libera.Chat, the goal is to reduce the number of patch version and
ease the review and maintainance process.
Concerning the link-name property, I think it should be done afterwards
since it's not necessary to support audio on A1, and I think it could
be extended to other SoC boards (which would be a great feature).

If you don't mind, I will send this change in a separate patch series.
Although I don't have support for all boards in the linux-amlogic, I can
test it on some Khadas and Odroid boards on my side. I will prepare link
names for them.

If you don't mind, I will send this change in a separate patch series.

names for them.
