[alsa-devel] snd_usb_endpoint_free
by Julia Lawall 25 Jun '14

25 Jun '14

The function snd_usb_endpoint_free in sound/usb/endpoint.c is defined as follows: void snd_usb_endpoint_free(struct list_head *head) { struct snd_usb_endpoint *ep; ep = list_entry(head, struct snd_usb_endpoint, list); release_urbs(ep, 1); kfree(ep); } I wonder if the final kfree should be list_del? In practice, this function is only used from snd_usb_audio_disconnect in sound/usb/card.c where the entire list is destroyed, but it seems like quite a generic function that someone may someday want to use for just freeing one entry. julia

[alsa-devel] [PATCH v6 0/3] Add ES8328 audio codec
by Sean Cross 25 Jun '14

25 Jun '14

This patchset adds support for the Everest Semi ES8328 audio codec. It also adds support for using the es8328 on IMX boards. We write a machine driver rather than using simple-card because the machine driver needs to support regulators for the speaker amps and as well as supporting headphone jacks. Changes since v5: - Removed empty imx_set_frequency function from imx-es8328.c - Move the clock from imx-audio-es8328 to the es8328 codec itself - Add support for 2x (22.5792 MHz) and 1x (11.2896 MHz) source clocks - Restore registers on resume - Document pins for ES8328, including input pins Changes since v4: - Simplify clock handling and use assigned-clock-parents - Move the codec regulator from the machine driver to the codec - Specify all four regulators, and require their presence - Fix audio recording, such that it enables the PGA Changes since v3: - Add OF bindings for everest,es8328 - Add back in patch to add everest as a vendor prefix - Give clocks more generic names - Document required clocks in DT bindings document Changes since v2: - Change deemph to a bool, and update based on sample rate - Replace value enums with regular enums - Break SPI and I2C drivers into their own modules - Rename everest,es8328 to es8328 as the module wasn't getting detected. Because of this, the patch to vendor-prefixes.txt has been dropped. Changes since v1: - Rename HP/Speaker to OUT1/OUT2 - Use DAPM widgets for startup/shutdown - Add regulator support to machine driver Sean Cross (3): devicetree: bindings: Add Everest Semicodunctor ASoC: add es8328 codec driver ASoC: fsl: add imx-es8328 machine driver Documentation/devicetree/bindings/sound/es8328.txt | 38 ++ .../devicetree/bindings/sound/imx-audio-es8328.txt | 61 ++ .../devicetree/bindings/vendor-prefixes.txt | 1 + sound/soc/codecs/Kconfig | 13 + sound/soc/codecs/Makefile | 6 + sound/soc/codecs/es8328-i2c.c | 60 ++ sound/soc/codecs/es8328-spi.c | 49 ++ sound/soc/codecs/es8328.c | 719 +++++++++++++++++++++ sound/soc/codecs/es8328.h | 314 +++++++++ sound/soc/fsl/Kconfig | 14 + sound/soc/fsl/Makefile | 2 + sound/soc/fsl/imx-es8328.c | 224 +++++++ 12 files changed, 1501 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/es8328.txt create mode 100644 Documentation/devicetree/bindings/sound/imx-audio-es8328.txt create mode 100644 sound/soc/codecs/es8328-i2c.c create mode 100644 sound/soc/codecs/es8328-spi.c create mode 100644 sound/soc/codecs/es8328.c create mode 100644 sound/soc/codecs/es8328.h create mode 100644 sound/soc/fsl/imx-es8328.c -- 2.0.0

[alsa-devel] [PATCH] ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13
by Takashi Iwai 24 Jun '14

24 Jun '14

HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).

[alsa-devel] [PATCH 0/4 v2] arizona: Improvements to codec DVFS control
by Charles Keepax 23 Jun '14

23 Jun '14

Hi, Respin of Richard's DVFS series, from me since he is on holiday. I have based these on Mark's ASoC for-next branch as there a few changes in there to the same parts of code. But let me know if you would rather have a series based on Lee's tree instead. This set of changes cleans up the way the drivers handle the control of internal subsystem clocks for codecs with DVFS. This previously relied on the clock control happening as a side-effect of changing the regulator voltage, rather than explicitly, which assumed that you were using the built-in regulator. Also DVFS control was being done from the ADSP driver despite that driver supposedly being codec- agnostic. There are other cases on some codecs where DVFS control is needed so this sequence of patches cleans up the way DVFS is implemented and adds the extra case of DVFS boost for higher sample rates on WM8997 and WM5102 Changes since v1: - Changed mask variable to flags to be more consistent with its usage - Fixed minor tabbing issue - Adding missing SND_SOC_DAPM_PRE_PMD event flag in WM_ADSP2_E Richard Fitzgerald (4): mfd: arizona: Export function to control subsystem DVFS ASoC: wm_adsp: Move DVFS control into codec driver ASoC: arizona: Add DVFS handling for sample rate control regulator: arizona-ldo1: Do not control clocking from regulator drivers/mfd/arizona-core.c | 84 ++++++++++++++++++++++++++++++++++++++ drivers/regulator/arizona-ldo1.c | 5 -- include/linux/mfd/arizona/core.h | 12 +++++ sound/soc/codecs/arizona.c | 22 +++++++++- sound/soc/codecs/wm5102.c | 47 ++++++++++++++++++++- sound/soc/codecs/wm5110.c | 2 +- sound/soc/codecs/wm_adsp.c | 73 +-------------------------------- sound/soc/codecs/wm_adsp.h | 13 +++--- 8 files changed, 171 insertions(+), 87 deletions(-) -- 1.7.2.5

[alsa-devel] [RFT v3 0/3] ASoC: core: Add support for DAI multicodec
by Benoit Cousson 23 Jun '14

23 Jun '14

Hi Mark, Liam and Lars, Sorry for the delay. Here is the third version of the multicodec series. I changed the way to store the multiple codec_dai as suggested by Lars and added the missing iterations in all the places pointed by Lars in his comments. Please note that I have a very simple setup based on BBB to check if the series is working, so it will be good to test it on various platforms to ensure this is not generating any regression. Hence this version is still RFT. The series is based on asoc/for-next (v3.15-rc2). Test and comments are welcome. Thanks, Benoit v1: http://comments.gmane.org/gmane.linux.alsa.devel/120532 v2: http://comments.gmane.org/gmane.linux.alsa.devel/121024 - Split the first version in several patches. - Remove the TDM fixup v3: - Fixed all the places that were not iterating over all the codecs. - Change the structure and split it.

[alsa-devel] [PATCH v2 00/11] ASoC: Add support for DAPM at the component level
by Lars-Peter Clausen 23 Jun '14

23 Jun '14

Changes since v1: * Rebased onto asoc/for-next and 3.16-rc1 * Added patch to remove platform field from widget and DAPM context to prevent new users from being added Original cover letter: Hi, This series is the next step in componentization. It moves the DAPM support to the component level. This will allow any component to have DAPM widgets and routes, which was previously only possible for CODECs, and will allow any component to have DAPM widgets with controls (i.e. Mixers and MUXs), which was previously only possible for CODECs. At the end of this patchset the DAPM code will have (almost) no dependency on snd_soc_codec or snd_soc_platform and the dependency on snd_soc_component is confined to 4 small helper functions. The only reason why there is still snd_soc_codec/snd_soc_platform dependent code is because there are still a lot of drivers which use widget->codec/platform and dapm->codec/platform. So those still need to be initialized. This will be cleaned up in a separate series and once that's done the codec and platform fields will be removed from the widget and DAPM context struct. One of the major problems of moving DAPM to the component level is that the DAPM context is directly embedded in the snd_soc_codec and snd_soc_platform structs and there are many drivers directly accessing that embedded field. This means it is not possible to move the field without causing a bit of code churn in the drivers. The patch series solves this by adding two fields to the component struct. One pointer to a DAPM context, which points to the DAPM context that is used by the component. And one DAPM context, which is used as the default if no other DAPM context was provided. Neither of the fields is accessed directly, instead a inline helper function is added that returns the DAPM context for a component. This will make it possible to eventually seamlessly switch over once all direct references to CODEC and platform DAPM contexts have been eliminated. - Lars Lars-Peter Clausen (11): ASoC: Move name_prefix from CODEC to component ASoC: Move name and id from CODEC/platform to component ASoC: Split component registration into two steps ASoC: Auto disconnect pins from all DAPM contexts ASoC: Add a set_bias_level() callback to the DAPM context struct ASoC: Add DAPM support at the component level ASoC: Use component DAPM context for platforms ASoC: Add component level stream_event() and seq_notifier() support ASoC: Add component level set_bias_level() support ASoC: dapm: Remove DAI DAPM context ASoC: dapm: Remove platform field from widget and dapm context struct include/sound/soc-dai.h | 1 - include/sound/soc-dapm.h | 8 +- include/sound/soc.h | 53 +++++-- include/trace/events/asoc.h | 6 +- sound/soc/codecs/tlv320dac33.c | 2 +- sound/soc/soc-cache.c | 7 +- sound/soc/soc-compress.c | 8 +- sound/soc/soc-core.c | 330 +++++++++++++++++++++++------------------ sound/soc/soc-dapm.c | 183 +++++++++++++---------- sound/soc/soc-pcm.c | 4 +- 10 files changed, 344 insertions(+), 258 deletions(-) -- 1.8.0

[alsa-devel] [PATCH] ASoC: fsl: refine DMA/FIQ dependencies
by Arnd Bergmann 22 Jun '14

22 Jun '14

Commit 31ee2bfd724ab ("ASoC: fsl: select SND_SOC_IMX_PCM_DMA where needed") started selecting SND_SOC_IMX_PCM_DMA and SND_SOC_IMX_PCM_FIQ for two drivers when building for i.MX. This has turned out too aggressive, as FIQ is only available for i.mx2 through i.mx5, but not i.mx6 or vybrid. Further, two more drivers have become user-selectable in the meantime, and they both depend on DMA for the imx platform as well. This changes the selection of FIQ to depend on the TZIC or AVIC interrupt controllers that actually export the imx specific FIQ interfaces, and adds the missing select statements for SAI and ESAI.

[alsa-devel] [PATCH v5 0/3] Add ES8328 audio codec
by Sean Cross 21 Jun '14

21 Jun '14

This patchset adds support for the Everest Semi ES8328 audio codec. It also adds support for using the es8328 on IMX boards. We write a machine driver rather than using simple-card because the machine driver needs to support regulators for the speaker amps and as well as supporting headphone jacks. This requires support for DT clock reparenting in order to get the codec its 22.5792 MHz supply frequency. Changes since v4: - Simplify clock handling and use assigned-clock-parents - Move the codec regulator from the machine driver to the codec - Specify all four regulators, and require their presence - Fix audio recording, such that it enables the PGA Changes since v3: - Add OF bindings for everest,es8328 - Add back in patch to add everest as a vendor prefix - Give clocks more generic names - Document required clocks in DT bindings document Changes since v2: - Change deemph to a bool, and update based on sample rate - Replace value enums with regular enums - Break SPI and I2C drivers into their own modules - Rename everest,es8328 to es8328 as the module wasn't getting detected. Because of this, the patch to vendor-prefixes.txt has been dropped. Changes since v1: - Rename HP/Speaker to OUT1/OUT2 - Use DAPM widgets for startup/shutdown - Add regulator support to machine driver Sean Cross (3): devicetree: bindings: Add Everest Semicodunctor ASoC: add es8328 codec driver ASoC: fsl: add imx-es8328 machine driver Documentation/devicetree/bindings/sound/es8328.txt | 24 + .../devicetree/bindings/sound/imx-audio-es8328.txt | 63 ++ .../devicetree/bindings/vendor-prefixes.txt | 1 + sound/soc/codecs/Kconfig | 13 + sound/soc/codecs/Makefile | 6 + sound/soc/codecs/es8328-i2c.c | 60 ++ sound/soc/codecs/es8328-spi.c | 49 ++ sound/soc/codecs/es8328.c | 694 +++++++++++++++++++++ sound/soc/codecs/es8328.h | 313 ++++++++++ sound/soc/fsl/Kconfig | 14 + sound/soc/fsl/Makefile | 2 + sound/soc/fsl/imx-es8328.c | 263 ++++++++ 12 files changed, 1502 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/es8328.txt create mode 100644 Documentation/devicetree/bindings/sound/imx-audio-es8328.txt create mode 100644 sound/soc/codecs/es8328-i2c.c create mode 100644 sound/soc/codecs/es8328-spi.c create mode 100644 sound/soc/codecs/es8328.c create mode 100644 sound/soc/codecs/es8328.h create mode 100644 sound/soc/fsl/imx-es8328.c -- 2.0.0
