[alsa-devel] [PATCH 0/8] ASoC: s3c24xx_uda134x card fixes and cleanups
by Sylwester Nawrocki 25 Oct '16

25 Oct '16

This series might have a bit of an archaeological aspect, nevertheless my goal was to have sound working on one of the older S3C24XX SoC based boards for testing any patches touching the older Samsung SoC IP block related code. Together with patches: ASoC: samsung: Fix clock handling in S3C24XX_UDA134X card ARM: S3C24XX: Add dma_mask assignments for DMA devices ARM: S3C24XX: Add missing DMA device for Mini2440 board this series fixes sound on Micro2440SDK/mini2440 board broken since the 3.12 kernel release. I'm not sure how it worked before but currently the uda134x codec always fails to probe due to uninitialized platform_data, which is supposed to be set by the ASoC machine driver. This series addresses the issue by moving all required codec platform_data to the board file and exposing optional GPIO bitbang L3 bus ops which are selected by the codec. ASoC dependency patches: ASoC: samsung: Fix clock handling in S3C24XX_UDA134X card The patch "ARM: S3C24XX: Specify audio codec platform_data for mini2440 board" is for arm-soc but it would be good to merge whole series through one tree to avoid compilation breaks due to unmet dependencies. Sylwester Nawrocki (8): ASoC: L3 bus: Add default gpio ops ARM: S3C24XX: Specify audio codec platform_data for mini2440 board ASoC: uda134x: Optionally initialize L3 ops to default GPIO ops ASoC: s3c24xx_uda134x: Remove unused power() callback ASoC: s3c24xx_uda134x: Drop initialization of codec's platform data ASoC: samsung: Convert s3c24xx_uda134x to use devm_snd_soc_register_card() ASoC: samsung: s3c24xx_uda134x: debug/error trace cleanup ASoC: s3c244_uda134x: Allocate private data dynamically arch/arm/mach-s3c24xx/mach-mini2440.c | 19 ++++ include/sound/l3.h | 15 ++- include/sound/s3c24xx_uda134x.h | 1 - sound/soc/codecs/l3.c | 71 ++++++++++-- sound/soc/codecs/uda134x.c | 7 ++ sound/soc/samsung/s3c24xx_uda134x.c | 205 ++++++++++------------------------ 6 files changed, 158 insertions(+), 160 deletions(-) -- 1.9.1

[alsa-devel] Potential Audio miniconference at LPC/KS
by Mark Brown 24 Oct '16

24 Oct '16

Hi, As in previous years we're trying to organize an audio miniconference so we can get together and talk through issues, especially design decisons, face to face. This year we're trying a slightly different tack and trying to organize this as part of the workshops day at Kernel Summit and Linux Plumbers in Santa Fe the week 31st October to 4th November (I'm writing this offline so don't have the exact date for the workshop day, sorry). There is a wiki page with an initial list of proposed topics here: http://wiki.linuxplumbersconf.org/2016:workshops In order to get this workshop approved we're going to need both a clear set of things to discuss and visible interest from attendees so if people could both follow up here and add to the wiki with suggestions of topics that'd be especially appreciated. Thanks, Mark

[alsa-devel] [PATCH 0/2 v2][resend] DesignWare HDMI I2S suport

Hi Archit, Mark Cc Thierry, Russell These are resend of v2 of DesignWare HDMI I2S support patches. (I added drm-bridge maintainer Archit on To:) It will use ALSA SoC hdmi-codec driver, but we can't use it as-is at this point. 1) patch tidyup hdmi-codec driver to enable dw-hdmi I2S support. 2) patch is based on it. Difficult is that these 2 patches are under different maintainer. 1) Mark ? 2) Archit ?

[alsa-devel] [PATCH] ASoC: topology: Reenable use from userspace

We had inserted a #error into the topology UAPI code to ensure that the ABI was not adopted by userspace while final review and testing was ongoing. Since we are now comfortable that the ABI is suitable for production remove the #error, future changes will include provision for backwards compatibility.

[alsa-devel] [PATCH 0/5] ALSA: soc: fix sparse warnings
by Takashi Sakamoto 28 Sep '16

28 Sep '16

Hi, This patchset is to fix some sparse warnings in ALSA SoC part. Below items are going to be fixed: * fix a condition statement with a logical operation * purge old way to initialize array * missing 'static' qualifier for file local symbols Although I got many warnings from Intel SST drivers due to confusions of address spaces (__iomem and __kernel), I still left them as they are, because they require more codes to fix. I hope Intel developers will do additional work for them...

So we had some driver updates collated, time to send them upstream :) - manifest data size was not checked so that is fixed - previous conversion to use core parsing for HDA capabilities was wrong at one place, that is fixed. - DMA config size was wrong, that is also fixed - Add 32bit format - The module instance IDs are manged in driver now.

[alsa-devel] [PATCH 0/2] ASoC: Chromebook Pixel 2015 support
by John Keeping 25 Sep '16

25 Sep '16

These patches add basic support for audio on the Chromebook Pixel 2015. I took the machine driver from ChromeOS commit v3.14-10186-g7e7d95df2983 and other than removing support for wake on voice (which is not supported by the mainline rt5677 codec driver), the only differences are to cope with API changes since 3.14. Only two authors have committed changes to the machine driver in the ChromeOS tree and all of the commits are signed off; both authors' SoB lines are preserved in the second commit here. The codec driver is sufficiently different that I just added ACPI support from scratch using the ChromeOS source as a reference for the property names.
