[alsa-devel] [PATCH 1/2] ASoC: ak4118: Add support for AK4118 S/PDIF transceiver
by Clément Péron 15 Nov '18

15 Nov '18

From: Adrien Charruel <adrien.charruel(a)devialet.com> The AK4118A is a digital audio transceiver supporting 8 input channels at 192kHz and with 24bits resolution. It converts the S/PDIF signal to I2S format and is configurable over I2C. This driver introduce a minimal support of the AK4118, like selecting the input channel, reading input frequency and detecting some errors.

[alsa-devel] [RFC][PATCH] ASoC: rsnd: add SSIU BUSIF support
by Kuninori Morimoto 15 Nov '18

15 Nov '18

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU. Current driver is assuming it is using BUSIF0 as default. Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach(). But, TDM split mode also needs other BUSIF to use it. This patch adds missing SSIU BUSIFx support. BUSIF is handled by SSIU instead of SSI anymore. Thus, its settings no longer needed on SSI node on DT. This patch removes its settings from Document, but driver is still keeping compatibility. Thus, old DT style is still working. But, to avoid confusing, it doesn't indicate old compatiblity things on Document. New SoC should have SSIU on DT from this patch. 1) old style DT is still supported (= no rcar_sound,ssiu node on DT) 2) If ssiu is not indicated on playback/capture, BUSIF0 will be used as default playback = <&ssi3>; /* ssiu30 will be selected */ 3) you can select own ssiu playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */ Not-yet-Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> --- > Jiada This patch supports BUSIF, you can select it on DT. Is this style OK for you ? For example playback = <&src0 &dvc0 &ssiu02 &ssi0>; ~~~~~~~ It is keeping compatiblity. no <&ssiu> is still OK playback = <&src0 &dvc0 &ssi0>; .../devicetree/bindings/sound/renesas,rsnd.txt | 78 ++++----- sound/soc/sh/rcar/core.c | 1 + sound/soc/sh/rcar/dma.c | 37 ++++- sound/soc/sh/rcar/rsnd.h | 6 +- sound/soc/sh/rcar/ssi.c | 22 +-- sound/soc/sh/rcar/ssiu.c | 178 +++++++++++++++++++-- 6 files changed, 255 insertions(+), 67 deletions(-) diff --git a/Documentation/devicetree/bindings/sound/renesas,rsnd.txt b/Documentation/devicetree/bindings/sound/renesas,rsnd.txt index d92b705..8dfbe5b 100644 --- a/Documentation/devicetree/bindings/sound/renesas,rsnd.txt +++ b/Documentation/devicetree/bindings/sound/renesas,rsnd.txt @@ -363,6 +363,9 @@ Required properties: - rcar_sound,ssi : Should contain SSI feature.

[alsa-devel] [PATCH] ASoC: dapm: Recalculate audio map forcely when card instantiated
by Tzung-Bi Shih 14 Nov '18

14 Nov '18

Audio map are possible in wrong state before card->instantiated has been set to true. Imaging the following examples: time 1: at the beginning in:-1 in:-1 in:-1 in:-1 out:-1 out:-1 out:-1 out:-1 SIGGEN A B Spk time 2: after someone called snd_soc_dapm_new_widgets() (e.g. create_fill_widget_route_map() in sound/soc/codecs/hdac_hdmi.c) in:1 in:0 in:0 in:0 out:0 out:0 out:0 out:1 SIGGEN A B Spk time 3: routes added in:1 in:0 in:0 in:0 out:0 out:0 out:0 out:1 SIGGEN -----> A -----> B ---> Spk In the end, the path should be powered on but it did not. At time 3, "in" of SIGGEN and "out" of Spk did not propagate to their neighbors because snd_soc_dapm_add_path() will not invalidate the paths if the card has not instantiated (i.e. card->instantiated is false). To correct the state of audio map, recalculate the whole map forcely.

[alsa-devel] Applied "ASoC: pcm3060: Add DT property for single-ended output" to the asoc tree

14 Nov '18

The patch ASoC: pcm3060: Add DT property for single-ended output 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.

[alsa-devel] [PATCH] ASoC: omap-abe-twl6040: Fix missing audio card caused by deferred probing

Further investigation showed that on the second try of loading fails because the dai_link->platform is no longer NULL and it might be pointing to uninitialized memory. The fix is to move the snd_soc_dai_link and snd_soc_card inside of the abe_twl6040 struct, which is dynamically allocated every time the driver probes.

[alsa-devel] alsa-utils: axfer: rewrite aplay, adding 'timer-based scheduling' option
by GitHub pull_request - opened 14 Nov '18

14 Nov '18

alsa-project/alsa-utils pull request #3 was opened from takaswie: Hi, This patchset is an updated version of my previous RFCv3, and for merging to upstream. [alsa-devel] [RFCv3][PATCH 00/39] axfer: rewrite aplay, adding 'timer-based scheduling' option http://mailman.alsa-project.org/pipermail/alsa-devel/2017-October/125961.ht… As I noted in RFCv3, some patches are dropped in this patchset, due to some technical issues. In detail, please refer to RFCv3. Changes from RFCv3: - rename scheduling option to 'sched-model' - improve waiter implementation and add support for select(2) - categorize supported options as common and backend-dependent - release alsa-lib configuration space at the end of runtime - valgrind test and fix some memory leaks - add 'frame-cache' internal interface to share implementation by several backends. - add 'libffado' backend just for technical preview (linkage of this library brings problems. Please refet to patch comment.) I apologize but in this time I don't prepare any help document and manuals as well as RFCv3. Let me put them to a part of task for this development period.
