[PATCH 0/35] ASoC: rsnd: add CTU/MIX prototype support

[Kuninori Morimoto]

Hi Mark, Simon

These patches add CTU/MIX prototype support on Renesas sound card driver.
It needs DPCM feature, so it is assuming to be used via rsrc-card sound card.
These CTU/MIX is still prototype support. This Mixer works well if sound A and B
are using same bit length, same sampling rate.

 1) -  2) adds audio prefix support on DT which is needed on DPCM
 3) - 29) cleanup/tidyup/workaround/prepare patches for CTU/MIX support
30) - 31) CTU/MIX support on driver
32) - 35) CTU/MIX support on SoC

Simon, This time I didn't Cc:ed to SH-ML, since 32) - 35) need
Document update (?). It is done on 30) - 31).
I can post 32) - 35) if Mark accepted 1) - 31)

[PATCH 01/35] ASoC: core: add snd_soc_of_parse_audio_prefix()

[Kuninori Morimoto]

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

Current ASoC can add name_prefix for DAPM, and it is necessary for
route settings. This patch adds snd_soc_of_parse_audio_prefix() for
this purpose. It will be used with snd_soc_of_parse_audio_routing().

[PATCH 08/35] ASoC: rsnd: fixup each module counter on __rsnd_mod_call()

[Kuninori Morimoto]

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

'5451ea443b ("ASoC: rsnd: count each mod (SSI/SRC/DVC)")' counts each
module's callback status, but counts 1st callback only.
This patch fixup it. Otherwise, multi-called function will be trouble

[PATCH 17/35] ASoC: rsnd: add rsnd_path_parse() for CTU/MIX/DVC route setting

[Kuninori Morimoto]

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

Current sound data route settings is done in dvc.c, and it doesn't care
about CTU/MIX at this poinnt, but we need to care about these.
OTOH, rsnd driver already has rsnd_path_xxx() functions for data path which
are good match for CTU/MIX/DVC path selectio.
This patch adds new rsnd_path_parse() to select sound data route which will
care about CTU/MIX/DVC path.

[PATCH 18/35] ASoC: rsnd: add rsnd_dvc_initialize_lock/unlock()

[Kuninori Morimoto]

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

Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC,
and these have similar register. xxxIR (Initialization Register) is one
of them. These xxxIR need be set to 1 during initialization.
Current rsnd driver has src.c / dvc.c, and we will have mix.c.
It is readable if these have same named function.
This patch adds rsnd_dvc_initialize_lock/unlock() and make sure it

[PATCH 20/35] ASoC: rsnd: tidyup ADINR function name

[Kuninori Morimoto]

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

Renesas sound IP (= SSIU/SRC/CTU/MIX/DVC) have ADINR
(= Audio Information Register), but some of them (= SSIU/SRC/DVC)
are for audio data bits, some of them (= CTU/MIX) are for audio data
channels.
Current rsnd driver is supporting SSIU/SRC/DVC, and these ADINR were
for bits. This patch rename rsnd_get_adinr() to rsnd_get_adinr_bit(),
and we will have rsnd_get_adinr_chan() for CTU/MIX.

[PATCH 22/35] ASoC: rsnd: tidyup data align position

[Kuninori Morimoto]

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

Sound L/R order of SSI is different from Linux sound data order.
So current rsnd driver is using DALIGN (= data align) to exchange data
align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
sound volume will be exchanged if user used volume control on DVC.
Because SSIU which exchanges data align is located after DVC.

	MEM -> SRC -> DVC -> SSI

This patch exchanges data align SRC if possible

[PATCH 29/35] ASoC: rsnd: update Audio DMA path search method

[Kuninori Morimoto]

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

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.

[PATCH 30/35] ASoC: rsnd: add CTU (Channel Transfer Unit) prototype support

[Kuninori Morimoto]

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

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.

[PATCH 31/35] ASoC: rsnd: add MIX (Mixer) support

[Kuninori Morimoto]

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

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>;
			};
		};
	};

Applied "ASoC: core: add snd_soc_of_parse_audio_prefix()" to the asoc tree

[Mark Brown]

The patch

   ASoC: core: add snd_soc_of_parse_audio_prefix()

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: core: add snd_soc_of_parse_audio_prefix()

Current ASoC can add name_prefix for DAPM, and it is necessary for
route settings. This patch adds snd_soc_of_parse_audio_prefix() for
this purpose. It will be used with snd_soc_of_parse_audio_routing().

Applied "ASoC: rsnd: rsnd_mod_id() return -1 if mod was NULL" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: rsnd_mod_id() return -1 if mod was NULL

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Applied "ASoC: rsnd: remove unnecessary 'out of memory' message from SSI" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: remove unnecessary 'out of memory' message from SSI

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and

*Please* don't submit such large patch serieses unless you really need
to, it's a lot to review at once.  It's best to split things up to
smaller sets to be easier to work with.  For example with this set it'd
be better to send the cleanups and tidyups first (ideally one kind of
cleanup at a time) then the new feature.

Subject: [PATCH] ASoC: rsnd: tidyup data align position

Sound L/R order of SSI is different from Linux sound data order.
So current rsnd driver is using DALIGN (= data align) to exchange data
align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
sound volume will be exchanged if user used volume control on DVC.
Because SSIU which exchanges data align is located after DVC.

	MEM -> SRC -> DVC -> SSI

This patch exchanges data align SRC if possible

Renesas sound IP (= SSIU/SRC/CTU/MIX/DVC) have ADINR
(= Audio Information Register), but some of them (= SSIU/SRC/DVC)
are for audio data bits, some of them (= CTU/MIX) are for audio data
channels.
Current rsnd driver is supporting SSIU/SRC/DVC, and these ADINR were
for bits. This patch rename rsnd_get_adinr() to rsnd_get_adinr_bit(),
and we will have rsnd_get_adinr_chan() for CTU/MIX.

Applied "ASoC: rsnd: add rsnd_src_initialize_lock/unlock()" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: add rsnd_src_initialize_lock/unlock()

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] ASoC: rsnd: add rsnd_src_initialize_lock/unlock()

Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC,
and these have similar register. xxxIR (Initialization Register) is one
of them. These xxxIR need be set to 1 during initialization.
Current rsnd driver has src.c / dvc.c, and we will have mix.c.
It is readable if these have same named function.
This patch adds rsnd_src_initialize_lock/unlock() and make sure it

Subject: [PATCH] ASoC: rsnd: add rsnd_path_parse() for CTU/MIX/DVC route
 setting

Current sound data route settings is done in dvc.c, and it doesn't care
about CTU/MIX at this poinnt, but we need to care about these.
OTOH, rsnd driver already has rsnd_path_xxx() functions for data path which
are good match for CTU/MIX/DVC path selectio.
This patch adds new rsnd_path_parse() to select sound data route which will
care about CTU/MIX/DVC path.

   ASoC: rsnd: src: make sure SRC soft reset

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: rsnd: src: make sure SRC soft reset

Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC,
and these have similar register. xxxRSR (Software reset Register) is one
of them. These xxxRSR need be set to 1 to 0 when software reset.
Current rsnd driver has src.c / dvc.c, and we will have mix.c.
It is readable if these have same named function.
This patch adds rsnd_src_soft_reset() and make sure it

Subject: [PATCH] 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.

					    |
					    +-> [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>;
			};
		};
	};

Applied "ASoC: rsnd: add CTU (Channel Transfer Unit) prototype support" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: add CTU (Channel Transfer Unit) prototype support

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] 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.

   ASoC: rsnd: update Audio DMA path search method

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,

Subject: [PATCH] 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.
