[alsa-devel] Applied "ASoC: Revert "ASoC: soc-generic-dmaengine-pcm: Fix error handling"" to the asoc tree
by Mark Brown 26 Feb '18

26 Feb '18

The patch ASoC: Revert "ASoC: soc-generic-dmaengine-pcm: Fix error handling" 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 b84acf44d5b86597cebcb6aca16e7dd9ca2b0294 Mon Sep 17 00:00:00 2001 From: Fabio Estevam <fabio.estevam(a)nxp.com> Date: Mon, 26 Feb 2018 15:55:25 -0300 Subject: [PATCH] ASoC: Revert "ASoC: soc-generic-dmaengine-pcm: Fix error handling" This reverts commit f91b1e73ccde71d4bc69ae10d475196df38844ab. As explained by Lars-Peter Clausen: "This creates a resource leak. dmaengine_pcm_request_chan_of() requests bothtransmit and receive channels. It might return with an error if one of them fails, but the other one succeeded. In this case we need to call dmaengine_pcm_release_chan() to free the requested channel" So revert the commit.

From: Fabio Estevam <fabio.estevam(a)nxp.com> This reverts commit f91b1e73ccde71d4bc69ae10d475196df38844ab. As explained by Lars-Peter Clausen: "This creates a resource leak. dmaengine_pcm_request_chan_of() requests bothtransmit and receive channels. It might return with an error if one of them fails, but the other one succeeded. In this case we need to call dmaengine_pcm_release_chan() to free the requested channel" So revert the commit.

Unless we are missing something this is obviously a bug. I will try to have a look at the end of the week, but any comments are welcome. I think the fix would be to have one global priv structure and to unify imx_wm8962_data with imx_priv. thanks, Daniel.

[alsa-devel] [PATCH] ALSA: hda - Fix pincfg at resume on Lenovo T470 dock
by Takashi Iwai 26 Feb '18

26 Feb '18

We've added a quirk to enable the recent Lenovo dock support, where it overwrites the pin configs of NID 0x17 and 19, not only updating the pin config cache. It works right after the boot, but the problem is that the pin configs are occasionally cleared when the machine goes to PM. Meanwhile the quirk writes the pin configs only at the pre-probe, so this won't be applied any longer. For addressing that issue, this patch moves the code to overwrite the pin configs into HDA_FIXUP_ACT_INIT section so that it's always applied at both probe and resume time. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195161 Fixes: 61fcf8ece9b6 ("ALSA: hda/realtek - Enable Thinkpad Dock device for ALC298 platform") Cc: <stable(a)vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- sound/pci/hda/patch_realtek.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index ce28f7ce64e6..b9c93fa0a51c 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -4997,13 +4997,14 @@ static void alc_fixup_tpt470_dock(struct hda_codec *codec, if (action == HDA_FIXUP_ACT_PRE_PROBE) { spec->parse_flags = HDA_PINCFG_NO_HP_FIXUP; + snd_hda_apply_pincfgs(codec, pincfgs); + } else if (action == HDA_FIXUP_ACT_INIT) { /* Enable DOCK device */ snd_hda_codec_write(codec, 0x17, 0, AC_VERB_SET_CONFIG_DEFAULT_BYTES_3, 0); /* Enable DOCK device */ snd_hda_codec_write(codec, 0x19, 0, AC_VERB_SET_CONFIG_DEFAULT_BYTES_3, 0); - snd_hda_apply_pincfgs(codec, pincfgs); } } -- 2.16.2

[alsa-devel] [RFC PATCH 0/3] ASoC: stm32: add S/PDIF support to SAI
by Olivier Moysan 26 Feb '18

26 Feb '18

This patch-set adds S/PDIF IEC6958 protocol support to STM32 SAI. Only S/PDIF playback is supported here, as SAI peripheral does not support S/PDIF capture. SAI peripheral does not take as input full IEC60958 frames as it generates preamble and parity bit. However, it cannot handle raw PCM data, as it is not designed to insert channel status and user data in the generated IEC frames. Moreover, SAI data register format does not match exactly IEC60958 subframe format. (see figure below). Channel status (C) and User data (U) are at 26-25 bits position, in data register, instead of 30-29 bits position. IEC60958 subframe bits: 31-28 27-4 3-0 P C U V data (16|24 bits) preamble SAI data register format: 27-24 23-0 P C U V data (16|24 bits) The impact in software is that the data have to be processed before DMA transfer. These constraints should be managed at driver level to minimize the impact on application. This means that a callback is necessary to perform data processing (shift and channel status insertion) This patch-set introduces a callback to allow processing on samples. The implementation is based on previous discussions available here: https://patchwork.kernel.org/patch/9570255/ BRs Olivier Olivier Moysan (3): ASoC: stm32: Add S/PDIF to SAI bindings ASoC: dmaengine_pcm: add processing support ASoC: stm32: sai: Add support of S/PDIF playback .../devicetree/bindings/sound/st,stm32-sai.txt | 6 + include/sound/dmaengine_pcm.h | 3 + sound/soc/soc-generic-dmaengine-pcm.c | 62 ++++++++- sound/soc/stm/stm32_sai.c | 2 + sound/soc/stm/stm32_sai.h | 2 + sound/soc/stm/stm32_sai_sub.c | 153 +++++++++++++++++---- 6 files changed, 202 insertions(+), 26 deletions(-) -- 1.9.1
