[alsa-devel] [PATCH] ASoC: rsnd: update BSDSR/BSDISR handling
by Kuninori Morimoto 07 Jan '19

07 Jan '19

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Current BSDSR/BSDISR are using temporary/generic settings, but it can't handle all SRCx/SoC. It needs to handle correctry. Otherwise, sampling rate converted sound channel will be broken if it was TDM. One note is that it needs to overwrite settings on E3 case.

[alsa-devel] [PATCH 0/9] ASoC: Intel: fix Coccinelle and Sparse warnings

07 Jan '19

Make minor warnings go away to make sure Intel/SOF CI checks don't fail and new issues are detected.

[alsa-devel] [PATCH 0/4] ASoC: remove audio-graph-scu / simple-scu

Hi Mark In previous "audio-graph / simple" card merging patch-set, I mentioned I will post "remove scu" patch in next version for more safety. But I was confused. There is no xx-scu-card user on upstream (only me, locally).

[alsa-devel] [PATCH v2 0/3] add Xilinx audio formatter driver
by Maruthi Srinivas Bayyavarapu 07 Jan '19

Audio formatter IP supports two streaming interfaces - MM2S for playback and S2MM for capture. The driver enables DMA functionality for both the interfaces. Patchset includes devicetree bindings documentation, driver and build enablement.

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 sound/soc/generic/audio-graph-card.c | 465 +++++++++++++++++++--------------- sound/soc/generic/simple-card-utils.c | 14 +- sound/soc/generic/simple-card.c | 454 ++++++++++++++++++++------------- 3 files changed, 553 insertions(+), 380 deletions(-) -- 2.7.4

[alsa-devel] [PATCH 1/2] ASoC: rockchip: support ACODEC for rk3328
by Katsuhiro Suzuki 07 Jan '19

07 Jan '19

This patch adds support for audio CODEC core of rk3328. Rockchip does not publish detail specification of this core but driver source code is opened on their GitHub repository. https://github.com/rockchip-linux/kernel So I ported this code to linux-next and added some trivial fixes.

[alsa-devel] [PATCH] ASoC: xlnx: fix error handling in xlnx_formatter_pcm_probe
by Gustavo A. R. Silva 07 Jan '19

07 Jan '19

Currently, if platform_get_irq_byname() fails, the returned error turns into a huge value, once it is being store into a variable of type unsigned int, hence never actually reporting any error and causing unexpected behavior when using the values stored in aud_drv_data->s2mm_irq and aud_drv_data->mm2s_irq. Fix this by changing the type of variables s2mm_irq and mm2s_irq in structure xlnx_pcm_drv_data from unsigned int to int.
