[PATCH 0/6] ASoC: extra format on each DAI

[PATCH 0/6] ASoC: extra format on each DAI

[Kuninori Morimoto]

Hi Mark
Cc Stephen

Current clock provider/consumer setting is set by dai_link->dai_fmt, and it
is Codec base on Sound Card driver (= SND_SOC_DAIFMT_CBx_CFx).

Current CPU/Codec drivers are already based on its own base
(= SND_SOC_DAIFMT_Bx_Fx). So, Codec clock setting uses dai_link->dai_fmt
as-is, and CPU side clock setting is created from Codec base setting by
flipping. Because of this, we can't set both CPU/Codec clock consumer for
example.

To solve this issue, this patch-set adds new ext_fmt on each DAI.
It can keep compatible with legacy style.

	1. SND_SOC_DAIFMT_FORMAT_MASK
	2. SND_SOC_DAIFMT_CLOCK
	3. SND_SOC_DAIFMT_INV
	4. SND_SOC_DAIFMT_CLOCK_PROVIDER

	dai_fmt : dai_link->dai_fmt = common settings
	ext_fmt : each DAI settings
    
Legacy
	dai_fmt  includes 1, 2, 3, 4
    
New style
	dai_fmt  includes 1, 2, 3
	ext_fmt  includes 4

Audio-Graph-Card2 will use this new style by this patch-set.
By this patch, its default behavior (= no "clock-master / frame-master"
settings on DT) will be changed, but no drivers are having it.

In case of no DAI has "clock-master / frame-master" settings on DT

Legacy
	CPU  : provider (because flipped from Codec)
	Codec: consumer

New style
	CPU  : consumer
	Codec: consumer

One note is that Simple-Card, Audio-Graph-Card don't implement
this new style to keep compatiblily.

2nd note is that [1/6] - [4/6] are normal patch-set,
[5/6] - [6/6] are [RFC]

[PATCH 1/6] ASoC: audio-graph-card2: use __free(device_node) for device node

[Kuninori Morimoto]

audio-graph-card2 handles many type of device_node, thus need to
use of_node_put() in many place. Let's use __free(device_node)
and avoid it.

[PATCH 2/6] ASoC: audio-graph-card: use __free(device_node) for device node

[Kuninori Morimoto]

audio-graph-card handles many type of device_node, thus need to
use of_node_put() in many place. Let's use __free(device_node)
and avoid it.

[PATCH 3/6] ASoC: simple-card: use __free(device_node) for device node

[Kuninori Morimoto]

simple-card handles many type of device_node, thus need to
use of_node_put() in many place. Let's use __free(device_node)
and avoid it.

[PATCH 4/6] ASoC: soc-core: return 0 if np was NULL on snd_soc_daifmt_parse_clock_provider_raw()

snd_soc_daifmt_parse_clock_provider_raw() might be called with NULL np.
Return 0 in such case.

[PATCH 6/6] ASoC: audio-graph-card2: Use extra format on each DAI

[Kuninori Morimoto]

Current ASoC is using dai_link->dai_fmt to set DAI format for both
CPU/Codec. But because it is using same settings, and
SND_SOC_DAIFMT_CLOCK_PROVIDER is flipped for CPU, we can't set both
CPU/Codec as clock consumer, for example.

To solve this issue, this patch uses extra format for each DAI which can
keep compatibility with legacy system,

	1. SND_SOC_DAIFMT_FORMAT_MASK
	2. SND_SOC_DAIFMT_CLOCK
	3. SND_SOC_DAIFMT_INV
	4. SND_SOC_DAIFMT_CLOCK_PROVIDER

Legacy
	dai_fmt  includes 1, 2, 3, 4

New idea
	dai_fmt  includes 1, 2, 3
	ext_fmt  includes 4

Hi Morimoto-san,

This patch (#6 of the set) was generated against a tree which didn't
have the port_cpu -> port_codec correction applied
(687630aa582acf674120c87350beb01d836c837c) and it fails when applied
against HEAD of
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/

Not sure if this is a problem...

Stephen

Ah, it seems above patch is...

	asoc/for-6.13 :     included
	asoc/for-6.14 : not included

Mark, is it possible to merge for-6.13 into for-6.14 ?
It can ignore conflict issue. I can post v2 patch-set on top of it.

Thank you for your help !!

Best regards

Yes, I tend to do that if there's dependency issues.  Just base on
for-next for now, I'll do a merge into for-6.14 before applying if I've
not already merged up mainline (I'm holding off on doing the latter for
now since the KVM people broke things again).

Thanks a lot !
I have updated based on for-next branch, and pushed.

Thank you for your help !!

[PATCH 5/6] ASoC: soc-core: Enable to use extra format on each DAI

[Kuninori Morimoto]

Current ASoC is using dai_link->dai_fmt to set DAI format for both
CPU/Codec. But because it is using same settings, and
SND_SOC_DAIFMT_CLOCK_PROVIDER is flipped for CPU, we can't set both
CPU/Codec as clock consumer, for example.

To solve this issue, this patch enable to use extra format for each
DAI which can keep compatibility with legacy system,

	1. SND_SOC_DAIFMT_FORMAT_MASK
	2. SND_SOC_DAIFMT_CLOCK
	3. SND_SOC_DAIFMT_INV
	4. SND_SOC_DAIFMT_CLOCK_PROVIDER

	Legacy
		dai_fmt  includes 1, 2, 3, 4

	New idea
		dai_fmt  includes 1, 2, 3
		ext_fmt  includes 4
