[alsa-devel] Question about OF-graph ports
by Kuninori Morimoto 26 Jan '17

26 Jan '17

Hi Rob, Mark and ALSA SoC ML I'm working for OF-graph base sound card support. Now I want to know 1 things which can't solve by myself. It is OF-graph ports ALSA SoC needs CPU, Codec, and Sound Card. If CPU <-> Card <-> Codec case, OF-graph will be card { ports { port@0 { card_in: endpoint { remote-endpoint = <&cpu_out>; }; }; port@1 { card_out: endpoint { remote-endpoint = <&codec_in>; }; }; }; }; cpu { port { cpu_out: endpoint { remote-endpoint = <&card_in>; }; }; }; codec { port { codec_in: endpoint { remote-endpoint = <&card_out>; }; }; }; This is OK. If CPU has many ports, then ALSA SoC requests 1 Card which has many DAIs (= Digital Audio Interface). This case, cpu will have "ports" and many "port", this is OK. SoC.0 Codec0 SoC.1 <-> Card <-> Codec1 SoC.2 Codec2 In "card", CPU/Codec pair is indicated by "ports" now (= port0 is CPU, port1 is Codec, etc) My question is in this case, how to know CPU/Codec pair on "card" ? Can we have *multi ports*, like this ? card { ports { ports@0 { port@0 { /* SoC.0 */ }; port@1 { /* Codec0*/ }; }; ports@1 { port@0 { /* SoC.1 */ }; port@1 { /* Codec1*/ }; }; ports@2 { port@0 { /* SoC.2 */ }; port@1 { /* Codec2*/ }; }; }; }; Or can I use grouping, like this ? card { group = <port@0 port@1>, <port@2 port@3>, <port@4 port@5>; ports { port@0 { /* SoC.0 */ }; port@1 { /* SoC.1 */ }; port@2 { /* SoC.2 */ }; port@3 { /* Codec0*/ }; port@4 { /* Codec1*/ }; port@5 { /* Codec2*/ }; }; }; Best regards --- Kuninori Morimoto

[alsa-devel] Applied "ASoC: cq93vc: remove MFD_DAVINCI_VOICECODEC dependency from CQ0093VC" to the asoc tree
by Mark Brown 25 Jan '17

25 Jan '17

The patch ASoC: cq93vc: remove MFD_DAVINCI_VOICECODEC dependency from CQ0093VC 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.

[alsa-devel] [PATCH][resend] ASoC: cq93vc: remove MFD_DAVINCI_VOICECODEC dependency from CQ0093VC
by Kuninori Morimoto 25 Jan '17

25 Jan '17

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> CQ0093VC is no longer dependent on MFD_DAVINCI_VOICECODEC, let's remove it. Otherwise, we can't compile it by COMPILE_TEST on non-DAVINCE platform Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> --- > Mark I couldn't find this patch on your repository today. It is based on below patch which is included on latest linus/master 8ca9edc837932469b81b8b47ea43a074b6add970 ("mfd: davinci_voicecodec: Tidyup header difinitions") sound/soc/codecs/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index b3fd110..a892937 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -45,7 +45,7 @@ config SND_SOC_ALL_CODECS select SND_SOC_ALC5623 if I2C select SND_SOC_ALC5632 if I2C select SND_SOC_BT_SCO - select SND_SOC_CQ0093VC if MFD_DAVINCI_VOICECODEC + select SND_SOC_CQ0093VC select SND_SOC_CS35L32 if I2C select SND_SOC_CS35L33 if I2C select SND_SOC_CS42L51_I2C if I2C -- 1.9.1

[alsa-devel] Applied "ASoC: hdac_hdmi: Register widget event handlers" to the asoc tree
by Mark Brown 24 Jan '17

24 Jan '17

The patch ASoC: hdac_hdmi: Register widget event handlers 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 >From c9bfb5d74dd2a704bf3c622c6b268f6dc6f37ca6 Mon Sep 17 00:00:00 2001 From: Jeeja KP <jeeja.kp(a)intel.com> Date: Tue, 24 Jan 2017 21:49:03 +0530 Subject: [PATCH] ASoC: hdac_hdmi: Register widget event handlers In case of hdmi connect/disconnect or when stream need to be route to multiple monitors, corresponding port and audio infoframe needs to be reconfigured. Currently all the configuration are done in DAI ops which results in silence playback. So use dapm widget event handlers to program audio infoframe and enable /disable port configuration when widget is power on/off.

[alsa-devel] [PATCH] ASoC: rsnd: fixup for_each_rsnd_mod_array{s} iterator increment
by Kuninori Morimoto 24 Jan '17

24 Jan '17

commit 5f222a292 ("ASoC: rsnd: use for_each_rsnd_mod_xxx() ...") modifies rsnd_dai_call() to use for_each_rsnd_mod_arrays(). Current rsnd is incrementing iterator in rsnd_mod_next(), but the iterator will indicate +1 position in for_each loop in this case. Incremental position should be inside for() Reported-by: Hoan Nguyen An <na-hoan(a)jinso.co.jp> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> --- Mark This is bugfix for v4.10.
