[alsa-devel] [PATCH v2 00/12] AC97 device/driver model revamp
by Robert Jarzmik 19 Sep '17

19 Sep '17

Hi Lars, Mark, Charles, Lee, This serie has been stalled for almost one year, as I wasn't feeling that well lately. I'm quite better now, so let's get back to it. As it's been so long since the last review, I basically withdrew all my former objections and took into account all remarks regardless of my own judgement. This is especially the case with Lars's review on the bus code, where I tried to address all his comments. For this next round, let's sum up what happened : - I rebased against latest Linus's tree => as Lars had made ports to regmap of several impacted wm97xx drivers, all the better for me. - ALSA: ac97: add an ac97 bus => this addresses Lars's comments => history : https://patchwork.kernel.org/patch/9398229/ => there is one remark which was left out, the drop of the table ac97_controller->codecs. The reason is that there are traversals required in the bus scan and controller removal, and the code is way simpler with a table, and the data structure very compact. - Input: wm97xx: split out touchscreen registering => Charles's comment taken into account => history: http://https://patchwork.kernel.org/patch/9398223/ Have a happy review. -- Robert Robert Jarzmik (11): ALSA: ac97: add an ac97 bus ASoC: add new ac97 bus support ASoC: arm: make pxa2xx-ac97-lib ac97 codec agnostic Input: wm97xx: split out touchscreen registering mfd: wm97xx-core: core support for wm97xx Codec Input: wm97xx: add new AC97 bus support ASoC: wm9713: add ac97 new bus support ASoC: wm9712: add ac97 new bus support ASoC: wm9705: add private structure ASoC: wm9705: add ac97 new bus support ASoC: pxa: switch to new ac97 bus support Takashi Iwai (1): ASoC: Fix use-after-free at card unregistration drivers/input/touchscreen/Kconfig | 2 +- drivers/input/touchscreen/wm97xx-core.c | 252 ++++++++++----- drivers/mfd/Kconfig | 14 + drivers/mfd/Makefile | 1 + drivers/mfd/wm97xx-core.c | 282 +++++++++++++++++ include/linux/mfd/wm97xx.h | 31 ++ include/sound/ac97/codec.h | 118 +++++++ include/sound/ac97/compat.h | 21 ++ include/sound/ac97/controller.h | 85 ++++++ include/sound/pxa2xx-lib.h | 15 +- sound/Kconfig | 2 + sound/Makefile | 1 + sound/ac97/Kconfig | 19 ++ sound/ac97/Makefile | 8 + sound/ac97/ac97_core.h | 10 + sound/ac97/bus.c | 526 ++++++++++++++++++++++++++++++++ sound/ac97/codec.c | 15 + sound/ac97/snd_ac97_compat.c | 105 +++++++ sound/arm/Kconfig | 1 - sound/arm/pxa2xx-ac97-lib.c | 37 ++- sound/arm/pxa2xx-ac97.c | 35 ++- sound/soc/Kconfig | 4 + sound/soc/codecs/Kconfig | 9 +- sound/soc/codecs/wm9705.c | 59 ++-- sound/soc/codecs/wm9712.c | 37 ++- sound/soc/codecs/wm9713.c | 39 ++- sound/soc/pxa/Kconfig | 5 +- sound/soc/pxa/pxa2xx-ac97.c | 43 ++- sound/soc/soc-core.c | 5 +- 29 files changed, 1603 insertions(+), 178 deletions(-) create mode 100644 drivers/mfd/wm97xx-core.c create mode 100644 include/linux/mfd/wm97xx.h create mode 100644 include/sound/ac97/codec.h create mode 100644 include/sound/ac97/compat.h create mode 100644 include/sound/ac97/controller.h create mode 100644 sound/ac97/Kconfig create mode 100644 sound/ac97/Makefile create mode 100644 sound/ac97/ac97_core.h create mode 100644 sound/ac97/bus.c create mode 100644 sound/ac97/codec.c create mode 100644 sound/ac97/snd_ac97_compat.c -- 2.1.4

[alsa-devel] [PATCH 0/9] AC97 device/driver model revamp
by Robert Jarzmik 19 Sep '17

19 Sep '17

It all started in the pxa device-tree submission here : https://lkml.org/lkml/2016/2/25/965 Last submission was a RFC in here: http://www.gossamer-threads.com/lists/linux/kernel/2446863 It will be maintained in : git fetch https://github.com/rjarzmik/linux.git work/ac97 The driving ideas are still the same, and I put them in [1] for memory. This is the first post RFC submission. In order to make a full demonstration of the framework, wm97xx was converted to an MFD, see [2] for the "why". As this serie is a complete wm9713 change towards the new AC97 bus, here is the patch organization : - 1/9, 2/9, 3/9 and 5/9: the new AC97 bus, for Mark and Takashi to review - 4/9: wm9713 conversion, this one has ugly #ifdefs, should be reviewed more carefully - 6/9: prerequisite for final 9/9, for Marek and Sebastian to approve => this one is independent and can flow through Sebastian's tree in this next-cycle if accepted - 7/9: prerequisite for final 9/9, for Mark/Dmitry => this one is also independent and can flow in this cycle if accepted - 8/9: prerequisite for final 9/9, for Lee to review => this one has a dependency on 2/9, so it probably can't fit in this next-cycle - 9/9: this last one depends on all the patches before, so it can't fit in this next-cycle As a sum-up, I'd like to push for review for this -next cycle at least the patches 1, 2, 3, 5, 6 and 9. Happy review. Robert Jarzmik (9): ALSA: ac97: split out the generic ac97 registers ALSA: ac97: add an ac97 bus ASoC: add new ac97 bus support ASoC: wm9713: add ac97 new bus support ASoC: pxa: switch to new ac97 bus support power_supply: wm97xx_battery: use power_supply_get_drvdata Input: wm97xx: split out touchscreen registering mfd: wm97xx-core: core support for wm97xx Codec Input: wm97xx: add new AC97 bus support drivers/input/touchscreen/Kconfig | 2 +- drivers/input/touchscreen/wm97xx-core.c | 247 +++++++++++----- drivers/mfd/Kconfig | 14 + drivers/mfd/Makefile | 1 + drivers/mfd/wm97xx-core.c | 282 ++++++++++++++++++ drivers/power/supply/wm97xx_battery.c | 25 +- include/linux/mfd/wm97xx.h | 31 ++ include/sound/ac97/codec.h | 115 +++++++ include/sound/ac97/compat.h | 21 ++ include/sound/ac97/controller.h | 85 ++++++ include/sound/ac97/regs.h | 262 ++++++++++++++++ include/sound/ac97_codec.h | 239 +-------------- include/sound/pxa2xx-lib.h | 15 +- sound/Kconfig | 2 + sound/Makefile | 1 + sound/ac97/Kconfig | 19 ++ sound/ac97/Makefile | 8 + sound/ac97/ac97_core.h | 10 + sound/ac97/bus.c | 510 ++++++++++++++++++++++++++++++++ sound/ac97/codec.c | 15 + sound/ac97/snd_ac97_compat.c | 105 +++++++ sound/arm/Kconfig | 1 - sound/arm/pxa2xx-ac97-lib.c | 39 ++- sound/soc/Kconfig | 4 + sound/soc/codecs/Kconfig | 3 +- sound/soc/codecs/wm9713.c | 37 ++- sound/soc/pxa/Kconfig | 5 +- sound/soc/pxa/pxa2xx-ac97.c | 22 +- 28 files changed, 1738 insertions(+), 382 deletions(-) create mode 100644 drivers/mfd/wm97xx-core.c create mode 100644 include/linux/mfd/wm97xx.h create mode 100644 include/sound/ac97/codec.h create mode 100644 include/sound/ac97/compat.h create mode 100644 include/sound/ac97/controller.h create mode 100644 include/sound/ac97/regs.h create mode 100644 sound/ac97/Kconfig create mode 100644 sound/ac97/Makefile create mode 100644 sound/ac97/ac97_core.h create mode 100644 sound/ac97/bus.c create mode 100644 sound/ac97/codec.c create mode 100644 sound/ac97/snd_ac97_compat.c -- 2.1.4 [1] RFC PATCH reminder: Amongst the driving ideas behind this RFC : - use device/driver model for AC'97 device/driver binding is based on vendor_id{1,2} - use auto-probe of the AC'97 bus to enumerate codecs and create devices - be compatible with previous platform_data model for codecs => this enables a smooth transition, where a codec (here wm9713) can be used either through platform_device or automatic discovery - struct snd_ac97 is not used This structure is really heavy, and doesn't represent an AC97 device, but rather an AC'97 codec internals IIUC. I think it's right place would be in include/sound/ac97/codec.h. This is also a problem for regmap adherence, hence the include/sound/ac97/compat.h. - a new AC'97 bus Kconfig is created This was done for a smooth transition ... let's see if it's a good idea. - split the AC'97 into : - the codec - the digital controller - the bus Amongst the things that are not all touched yet : - ac97_codec.c The generic AC'97 codec in sound/pci/ac97/ac97_codec.c has really a lot features, which are not at all PCI related. They could be transfered to sound/ac97, without the pci specific field. => this deserves a deep ahead thinking, which I'll do if the current approach is accepted by the communauty. The most important patch is 2/7 "ALSA: ac97: add an ac97 bus". This is the main evaluation point for the serie, the others are here so that I can test it all. Well, this is a long term effort, which might need a complete rewrite according to the comments it'll get. Let's expose it for comments and see how I can progress with it. [2] As a corollary, wm97xx is changed into a MFD device, which at least spawns: - the touchscreen device - the ac97 codec - the problem to solve was stated in http://www.gossamer-threads.com/lists/linux/kernel/2510113#2510113

[alsa-devel] [PATCH 0/2] Add ACPI table for the ts3a227e driver
by Thierry Escande 19 Sep '17

19 Sep '17

Hi, This series adds ACPI match table for the ts3a227e driver. The ts3a227e is an Autonomous Audio Accessory Detection and Configuration Switch used to detect audio accessory features like jack plugging and unplugging, mic presence, and button pressed events. This series also fixes a null pointer dereference occurring in the TI max9890 driver when the ts3a227e hardware is present and its driver probed. The jack detection was enabled in the ts3a227e driver before the jack structure was allocated, causing the null pointer access. Regards, Thierry Fang, Yang A (1): ASoC: ts3a227e: add acpi table Thierry Escande (1): ASoc: cht_bsw_max98090_ti: Fix jack initialization sound/soc/codecs/ts3a227e.c | 10 ++++++ sound/soc/intel/boards/cht_bsw_max98090_ti.c | 52 +++++++++++++++++----------- 2 files changed, 41 insertions(+), 21 deletions(-) -- 2.7.4

[alsa-devel] [PATCH v3 00/11] Add STM32 DFSDM support
by Arnaud Pouliquen 11 Sep '17

11 Sep '17

Hello, I kept it as RFC as i reworked the global design (but also because not full validated...). Regarding Mark and Jonathan's comments, I decided to try an implementation with DMA support in IIO instead of handling it in ASOC. Solution seems more straightforward but as DMA cyclic mode and associated buffer block API is not part of IIO today, I still need some hacks... To be honest, I tried to integrate DMA cyclic management and associated buffer block Consumer API. but no enough expertise on IIO to success... :( Advantage vs V2: - No more data processing need in ASoC , done in IIO - ASoC uses IIO consumer interface ( except for buffer callback) Drawback : - Need to create a "SPI bus" trigger to allo to use Buffer consumer API => Need to find a solution to set this trigger by default in IIO audio driver - No standard buffer management - Implement DMA cyclic in DFSDM IIO driver. - Define specific API to handle buffer callback per period instead of callback per samples generated by iio_push_to_buffers_with_timestamp. V2-V3 delta: - New patches to support ASoC DMA codec in DT - ASoC: Add Bindins for DMIC codec driver. - ASoC: codec: add DT support in dmic codec. - New patches to allow in-kernel set of IIO buffer size and watermark - IIO: consumer: allow to set buffer sizes. - IIO DFSDM drivers - Split audio and ADC support in 2 drivers. - Implement DMA cyclic mode. - Add SPI bus Trigger for buffer management. - IIO sigma delta adc drivers - Suppress "simple and rename driver. - ASoC driver - Suppress DMA engine. - Suppress copy ops. - Use IIO consmumer interface to enable/Disable DFSDM. Regards, Arnaud Arnaud Pouliquen (11): iio: Add hardware consumer support IIO: Add DT bindings for sigma delta adc modulator IIO: ADC: add sigma delta modulator support IIO: add DT bindings for stm32 DFSDM filter IIO: ADC: add stm32 DFSDM support for Sigma delta ADC IIO: ADC: add stm32 DFSDM support for PDM microphone IIO: consumer: allow to set buffer sizes ASoC: Add Bindins for DMIC codec driver ASoC: codec: add DT support in dmic codec ASoC: add bindings for stm32 DFSDM filter ASoC: stm32: add DFSDM DAI support .../bindings/iio/adc/sigma-delta-modulator.txt | 13 + .../bindings/iio/adc/st,stm32-dfsdm-adc.txt | 120 ++++ Documentation/devicetree/bindings/sound/dmic.txt | 11 + .../devicetree/bindings/sound/st,stm32-adfsdm.txt | 41 ++ drivers/iio/Kconfig | 6 + drivers/iio/Makefile | 1 + drivers/iio/adc/Kconfig | 50 ++ drivers/iio/adc/Makefile | 4 + drivers/iio/adc/sd_adc_modulator.c | 98 +++ drivers/iio/adc/stm32-dfsdm-adc.c | 419 ++++++++++++ drivers/iio/adc/stm32-dfsdm-audio.c | 720 +++++++++++++++++++++ drivers/iio/adc/stm32-dfsdm-core.c | 658 +++++++++++++++++++ drivers/iio/adc/stm32-dfsdm.h | 372 +++++++++++ drivers/iio/buffer/industrialio-buffer-cb.c | 12 + drivers/iio/hw_consumer.c | 156 +++++ include/linux/iio/adc/stm32-dfsdm-audio.h | 41 ++ include/linux/iio/consumer.h | 13 + include/linux/iio/hw_consumer.h | 12 + sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/codecs/dmic.c | 8 + sound/soc/stm/Kconfig | 10 + sound/soc/stm/Makefile | 2 + sound/soc/stm/stm32_adfsdm.c | 362 +++++++++++ 24 files changed, 3131 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/adc/sigma-delta-modulator.txt create mode 100644 Documentation/devicetree/bindings/iio/adc/st,stm32-dfsdm-adc.txt create mode 100644 Documentation/devicetree/bindings/sound/dmic.txt create mode 100644 Documentation/devicetree/bindings/sound/st,stm32-adfsdm.txt create mode 100644 drivers/iio/adc/sd_adc_modulator.c create mode 100644 drivers/iio/adc/stm32-dfsdm-adc.c create mode 100644 drivers/iio/adc/stm32-dfsdm-audio.c create mode 100644 drivers/iio/adc/stm32-dfsdm-core.c create mode 100644 drivers/iio/adc/stm32-dfsdm.h create mode 100644 drivers/iio/hw_consumer.c create mode 100644 include/linux/iio/adc/stm32-dfsdm-audio.h create mode 100644 include/linux/iio/hw_consumer.h create mode 100644 sound/soc/stm/Kconfig create mode 100644 sound/soc/stm/Makefile create mode 100644 sound/soc/stm/stm32_adfsdm.c V2: Patch-set associated to this RFC proposes an implementation of the DFSDM features shared between ASoC and IIO frameworks. Patch-set is only a Skeleton of the drivers, so a base to discuss and validate a design. It contains minimum code to allow probing (with DT) and to expose the ASoC and IIO ABI. Hope that is sufficent in a first step to allow to focus on APIs. In this patch-set there are two new APIs used: - IIO in-kern API: based on hw_customer API proposed by Lars - ASOC <-> IIO API inspired by API defined for hdmi-codec for ASoC/DRM interconnect. API is dedicated to DFSDM only. Notice also that this design is based on following assumption: - Audio stream ABI interface is ASoC, no access to data through IIO ABI for PDM. - ASoC DMA should be used for audio transfer as designed for real time stream. - Need some runtime parameters exchange between ASoC and IIO due to the correlation between the sample frequency, the DFSDM decimation factor and the associated scaling. - "ASoC: dmaengine_pcm: add copy support" patch: I added a patch in ASoC that allows to implement a copy function to process data after DMA transfer. Requested, as DFSDM samples captured contain channel ID on 8-LSB bits and need also a potential rescale to present DAT on 24-bits. - "IIO: ADC: add sigma delta modulator support" patch: Simple dummy driver created to support external Sigma delta modulator. It is binded to DFSDM driver through hw_customer API. - 1.9.1

[alsa-devel] [PATCH] streamline TLV320AIC23 drivers
by Jens Rottmann 02 Aug '17

02 Aug '17

The iMX-TLV320AIC23 driver isn't from Freescale, but from a company named Eukrea Electromatique, originally for their own boards. From the code I get the impression it is a bit older, its DT options use a differing naming scheme. Patch it up a bit: - Remove Eukrea naming, i.MX is from Freescale, TLV320AIC23 is from TI, driver was written by Eukrea, but it's DT capable, so it's not exclusive: - Kconfig option title - 'model' option - driver 'compatible' string - Other options just have changed over time, this driver remaining (one of) the last with the old semantics: - 'audio-codec' option (also moved from ssi node) - 'mux-int/ext-port' options - All options stay backwards compatible, the DT binding documents new and old names. CONFIG variable and files have not been renamed, though, so no need to change old defconfigs.
