[alsa-devel] [PATCH 00/13 v2] ASoC: audio/simple card tidyup/cleanup
Hi Mark
As I mentioned on off-list mail, I noticed that previous patch-set included many exchanges in 1 patch. Because of this, the reviewing was very difficult. I had break downed it into few more small patches. I hope it becomes more review-able
1) : for "reg" property issue, again. 2) - 7) : missing 1CPU-1Codec DPCM case, and cleanup for audio-graph 8) - 13) : missing 1CPU-1Codec DPCM case, and cleanup for simple-card
Kuninori Morimoto (13): 1) ASoC: simple-card-utils: check "reg" property on asoc_simple_card_get_dai_id() 2) ASoC: audio-graph-card: add asoc_graph_card_get_conversion() 3) ASoC: audio-graph-card: add 1 CPU : 1 Codec support again 4) ASoC: audio-graph-card: add link_info 5) ASoC: audio-graph-card: cleanup DAI link loop method - step1 6) ASoC: audio-graph-card: cleanup DAI link loop method - step2 7) ASoC: audio-graph-card: reduce naming prefix 8) ASoC: simple-card: add asoc_simple_card_get_conversion() 9) ASoC: simple-card: add 1 CPU : 1 Codec support again 10) ASoC: simple-card: add link_info 11) ASoC: simple-card: cleanup DAI link loop method - step1 12) ASoC: simple-card: cleanup DAI link loop method - step2 13) ASoC: simple-card: reduce naming prefix

We will get DAI ID from "reg" property if it has on DT, otherwise get it by counting port/endpoint.
But in below case, we need to get DAI ID = 0 via port reg = <0>, but current implementation returns ID = 1, because it can't judge ID = 0 was from "non reg" or "reg = <0>". Thus, it will count port/endpoint number as "non reg" case.
of_graph_parse_endpoint() implementation itself is not a problem, but because asoc_simple_card_get_dai_id() need to count port/endpoint number when "non reg" case, it need to know ID = 0 was from "non reg" or "reg = <0>". This patch fix this issue.
port { reg = <0>; xxxx: endpoint@0 { }; => xxxx: endpoint@1 { }; };

audio-graph-card is now supporting normal sound and DPCM sound. For DPCM sound, original sound card (= audio-graph-scu) had been supported 1 CPU : 1 Codec connection which uses hw_params_fixup() for convert-rate/channel. But, merged audio-graph-card is completely forgeting about it.
To re-support 1 CPU : 1 Codec DPCM for hw_params_fixup(), it need to judge whether it is DPCM by checking convert-rate/channel. For this purpose, this patch adds asoc_graph_card_get_conversion() as preparation

Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

The patch
ASoC: audio-graph-card: add link_info
has been applied to the asoc tree at
https://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

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:45:59 +0900 Subject: [PATCH] ASoC: audio-graph-card: add link_info
Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:45:59 +0900 Subject: [PATCH] ASoC: audio-graph-card: add link_info
Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch adds/modifies counting and parsing function for "normal sound" and "DPCM sound", and call it from link loop. This is prepare for cleanup DAI link loop method.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:05 +0900 Subject: [PATCH] ASoC: audio-graph-card: cleanup DAI link loop method - step1
Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch adds/modifies counting and parsing function for "normal sound" and "DPCM sound", and call it from link loop. This is prepare for cleanup DAI link loop method.

Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch cleanups the code by using asoc_graph_card_for_each_link() which judges normal link / DPCM link.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:20 +0900 Subject: [PATCH] ASoC: audio-graph-card: cleanup DAI link loop method - step2
Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch cleanups the code by using asoc_graph_card_for_each_link() which judges normal link / DPCM link.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:20 +0900 Subject: [PATCH] ASoC: audio-graph-card: cleanup DAI link loop method - step2
Current audio-graph-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch cleanups the code by using asoc_graph_card_for_each_link() which judges normal link / DPCM link.

Current audio-graph-card is using asoc_graph_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_graph_card_xxx() to graph_xxx().

The patch
ASoC: audio-graph-card: reduce naming prefix
has been applied to the asoc tree at
https://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

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:33 +0900 Subject: [PATCH] ASoC: audio-graph-card: reduce naming prefix
Current audio-graph-card is using asoc_graph_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_graph_card_xxx() to graph_xxx().

The patch
ASoC: audio-graph-card: reduce naming prefix
has been applied to the asoc tree at
https://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

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:33 +0900 Subject: [PATCH] ASoC: audio-graph-card: reduce naming prefix
Current audio-graph-card is using asoc_graph_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_graph_card_xxx() to graph_xxx().

The patch
ASoC: audio-graph-card: reduce naming prefix
has been applied to the asoc tree at
https://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

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:33 +0900 Subject: [PATCH] ASoC: audio-graph-card: reduce naming prefix
Current audio-graph-card is using asoc_graph_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_graph_card_xxx() to graph_xxx().

simple-card is now supporting normal sound and DPCM sound. For DPCM sound, original sound card (= simple-scu-card) had been supported 1 CPU : 1 Codec connection which uses hw_params_fixup() for convert-rate/channel. But, merged simple-card is completely forgeting about it.
To re-support 1 CPU : 1 Codec DPCM for hw_params_fixup(), it need to judge whether it is DPCM by checking convert-rate/channel. For this purpose, this patch adds asoc_simple_card_get_conversion() as preparation

Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

The patch
ASoC: simple-card: add link_info
has been applied to the asoc tree at
https://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

ASoC: simple-card: add link_info
has been applied to the asoc tree at
https://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.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:53 +0900 Subject: [PATCH] ASoC: simple-card: add link_info
Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:46:53 +0900 Subject: [PATCH] ASoC: simple-card: add link_info
Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
To preparing cleanup code, this patch adds link_info which handles number of DAIs/Links/Codec Conf, and CPU/Codec turn.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:47:23 +0900 Subject: [PATCH] ASoC: simple-card: cleanup DAI link loop method - step1
Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch adds/modifies counting and parsing function for "normal sound" and "DPCM sound", and call it from link loop. This is prepare for cleanup DAI link loop method.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:47:23 +0900 Subject: [PATCH] ASoC: simple-card: cleanup DAI link loop method - step1
Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch adds/modifies counting and parsing function for "normal sound" and "DPCM sound", and call it from link loop. This is prepare for cleanup DAI link loop method.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
Current simple-card is parsing DAI link for both "normal sound" and "DPCM sound". On this driver, it needs to count and parse DAIs/Links/Codec Conf from each links. Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch cleanups the code by using asoc_simple_card_for_each_link() which judges normal link / DPCM link.

Then, counting/parsing link loop are very similar, but using different implementation. Because of this background, the link loop code is very mysterious. Mystery code will be trouble in the future.
This patch cleanups the code by using asoc_simple_card_for_each_link() which judges normal link / DPCM link.

Current simple-card is using asoc_simple_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_simple_card_xxx() to simple_xxx().

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:47:34 +0900 Subject: [PATCH] ASoC: simple-card: reduce naming prefix
Current simple-card is using asoc_simple_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_simple_card_xxx() to simple_xxx().

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:47:34 +0900 Subject: [PATCH] ASoC: simple-card: reduce naming prefix
Current simple-card is using asoc_simple_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_simple_card_xxx() to simple_xxx().

The patch
ASoC: simple-card: reduce naming prefix
has been applied to the asoc tree at
https://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

The patch
ASoC: simple-card: reduce naming prefix
has been applied to the asoc tree at
https://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.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Thu, 20 Dec 2018 10:47:34 +0900 Subject: [PATCH] ASoC: simple-card: reduce naming prefix
Current simple-card is using asoc_simple_card_xxx() for function / data naming. Because of this long prefix, it is easy to be 80 character over. Let's reduce prefix from asoc_simple_card_xxx() to simple_xxx().
