[alsa-devel] Best representation for TDM devices
by Maxime Ripard 25 Jul '19

25 Jul '19

Hi, I'm currently working on a device that has two Analog's ADAU7002 connected to an I2S/TDM Controller (sound/soc/sunxi/sun4i-i2s.c, with some modifications), over the slots 1/2 and 3/4. The capture itself is working fine, however I'm not quite sure about the way to expose those streams to the userspace. Since I have two codecs, I have two links (described through simple-card) and thus two subdevices. However, the microphones connected are really separate streams, so ideally (I guess?) we should have 1 subdevice per microphone. An alternative would be that we capture the whole 4 channels and use dsnoop to demux them, but trying to use the device directly (using arecord -D hw:0) results in the ioctl to change the number of channels being rejected, I'm assuming because each codec only has 2 channels? So I'm a bit lost at this point about how I should go and expose this. I couldn't really find any similar setup either in the kernel. Any preferred way of doing this? Thanks!

[alsa-devel] [PATCH 1/3] ASoC: wm_adsp: Allow bus error handler to be called directly
by Charles Keepax 25 Jul '19

There is no need for end drivers to add helper functions to allow the bus error handler to be called, simply update the prototype so it can be called directly.

[alsa-devel] [PATCH 00/10] Add support for new SAI IP version
by Daniel Baluta 25 Jul '19

25 Jul '19

So far SAI IPs integrated with imx6 only supported one data line. Starting with imx7 and imx8 SAI integration support up to 8 data lines and multiple ways of combining the fifos for each data line. New SAI IP version introduces two new registers (Version and Parmeter registers) which are placed at the beginning of register address space. For this reason we need to fix the register's address. Patches 1 and 2 from Lucas enhance per SOC handling of SAI properties. Patches 3,4,5,6,7,8 allow SAI driver to read active data lines and fifo combine mode from DT. Patch 9 fixes new SAI register address space. Patch 10 enable SAI for imx7ulp and imx8mq. This patch introduces Daniel Baluta (8): ASoC: fsl_sai: Add registers definition for multiple datalines ASoC: fsl_sai: Update Tx/Rx channel enable mask ASoC: fsl_sai: Add support to enable multiple data lines ASoC: dt-bindings: Document dl_mask property ASoC: fsl_sai: Add support for FIFO combine mode ASoC: dt-bindings: Document fcomb_mode property ASoC: fsl_sai: Add support for SAI new version ASoC: fsl_sai: Add support for imx7ulp/imx8mq Lucas Stach (2): ASoC: fsl_sai: add of_match data ASoC: fsl_sai: derive TX FIFO watermark from FIFO depth .../devicetree/bindings/sound/fsl-sai.txt | 9 + sound/soc/fsl/fsl_sai.c | 393 +++++++++++++----- sound/soc/fsl/fsl_sai.h | 98 +++-- 3 files changed, 361 insertions(+), 139 deletions(-) -- 2.17.1

[alsa-devel] [PATCH 00/22] ReST conversion of text files without .txt extension
by Mauro Carvalho Chehab 25 Jul '19

25 Jul '19

This series converts the text files under Documentation with doesn't end neither .txt or .rst and are not part of ABI or features[1]. This series is at: https://git.linuxtv.org/mchehab/experimental.git/log/?h=rst_for_5_4_v2.1 And comes after the pending patches I had for v5.13 (some not applied yet): https://git.linuxtv.org/mchehab/experimental.git/log/?h=pending_docs_after_… [1] I submitted already a series to handle ABI and features. There are some files besides the ones there with, IMHO, it doesn't make sense to convert. So, I wrote a small ugly script to track the files waiting to be converted: #!/bin/bash find Documentation/ -name '*.txt'|grep -vE '(features/|devicetree/|sphinx/|output/|dax-hv-api.txt|draft-ietf-cipso-ipsecurity-01.txt|translations)' for i in $(find Documentation/ -type f|grep -v translations/|grep -v output/|grep -v devicetree|grep -v -E "\.(rst|txt|py|pyc|pl|dot|conf|svg|sh|awk|gif|S|inf|c|csv|css|vim|exceptions|modes)$"|grep -v ABI/ |grep -v Documentation/EDID/hex|grep -v dontdiff|grep -v Kconfig|grep -v Makefile|grep -v Module.symvers|grep -vE '\b(CodingStyle|SubmittingPatches|target-export-device|hotplug-script|wusb-cbaf)\b'|grep -v -E '(LICENSE|COPY|gitignore|Makefile|AUTHORS|TODO|CHANGES|CREDITS|ChangeLog)'|grep -v Documentation/virtual/kvm/devices/README); do echo $i; done After this patch series, the script reports 358 files missing conversion, all ending with .txt. >From those, ~40 files are already at ReST format - the ones at Documentation/*.txt - except for a couple of files there. So, there's around 320 files left to be converted after this series, with gives me hope that we may finally finish the conversion this year. Let's see.

[alsa-devel] [PATCH 0/6] ASoC: improve codec to codec link support
by Jerome Brunet 25 Jul '19

25 Jul '19

As explained in this previous series [0], on Amlogic, we are using codec to codec links to deal with the glue which is between the i2s backends and the synopsys hdmi controller. This worked well until I tried to .get_eld() support in the dw-hdmi-i2s driver. Doing so adds channel mapping controls to the codec. This shown several problem 1) .pcm_new() is not called on codec to codec links. struct snd_soc_pcm_runtime do not even have a valid .pcm 2) struct snd_pcm_substream and struct snd_pcm_runtime are ephemeral This is a problem if a control needs to access them The goal of this patchset is to resolve the above issues and improve the codec to codec link support enough to correctly handle the hdmi-codec The support of these codec to codec links could probably be improved in the future to behave like any other link and use soc_pcm_open(), soc_pcm_hw_params(), etc... The challenge lies in the dapm mutex. The soc_pcm call dapm function locking this mutex but the dapm mutex is already held in snd_soc_dai_link_event() [0]: https://lkml.kernel.org/r/20190515131858.32130-1-jbrunet@baylibre.com Jerome Brunet (6): ASoC: codec2codec: run callbacks in order ASoC: codec2codec: name link using stream direction ASoC: codec2codec: deal with params when necessary ASoC: create pcm for codec2codec links as well ASoC: codec2codec: remove ephemeral variables ASoC: codec2codec: fill some of the runtime stream parameters sound/soc/soc-core.c | 42 +++------- sound/soc/soc-dapm.c | 186 +++++++++++++++++++++++++++---------------- sound/soc/soc-pcm.c | 35 +++++++- 3 files changed, 162 insertions(+), 101 deletions(-) -- 2.21.0
