[alsa-devel] [PATCH v1 0/9] Basic sound support for Arndale board / wm8994 updates
by Sylwester Nawrocki 19 Sep '19

19 Sep '19

This patch series adds basic audio support for Exynos5250 SoC based Arndale board, the Bluetooth receiver source and HDMI output are not covered yet. There is also one fix for wm8994 driver related to WM1811 CODEC and wm8994 updates to handle MCLK clocks, similar to patches: ae1ea48c5c59 ("ASoC: arizona: Add gating for source clocks of the FLLs") 7a4413d0dc96 ("ASoC: arizona: Add gating for clock when used for direct MCLK") Sylwester Nawrocki (9): ASoC: wm8994: Do not register inapplicable controls for WM1811 mfd: wm8994: Add support for MCLKn clock control ASoC: wm8994: Add support for setting MCLKn clock rate ASoC: wm8994: Add support for MCLKn clock gating ASoC: samsung: arndale: Simplify DAI link initialization ASoC: dt-bindings: Document "samsung,arndale-wm1811" compatible ASoC: samsung: arndale: Add support for WM1811 CODEC ASoC: samsung: arndale: Add missing OF node dereferencing ARM: dts: arndale: Add audio support (WM1811 CODEC boards) .../devicetree/bindings/sound/arndale.txt | 5 +- arch/arm/boot/dts/exynos5250-arndale.dts | 27 ++- drivers/mfd/wm8994-core.c | 9 + include/linux/mfd/wm8994/core.h | 9 + sound/soc/codecs/wm8994.c | 164 +++++++++++++++--- sound/soc/samsung/arndale_rt5631.c | 155 +++++++++++++---- 6 files changed, 306 insertions(+), 63 deletions(-) -- 2.17.1

[alsa-devel] DPCM: suspicious code in dpcm_prune_paths()
by Guennadi Liakhovetski 19 Sep '19

19 Sep '19

Hi, This code in dpcm_prune_paths() seems to have no effect: /* is there a valid CODEC DAI widget for this BE */ for_each_rtd_codec_dai(dpcm->be, i, dai) { widget = dai_get_widget(dai, stream); /* prune the BE if it's no longer in our active list */ if (widget && widget_in_list(list, widget)) continue; } Neither of the variables, that are modified in this loop are used outside of it. Was the "continue" maybe meant to continue the encompassing loop? Thanks Guennadi

[alsa-devel] [PATCH v6 0/4] ASoC: codecs: Add WSA881x Smart Speaker amplifier support
by Srinivas Kandagatla 19 Sep '19

19 Sep '19

This patchset adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier which is SoundWire interfaced. This also adds support to some missing bits in SoundWire bus layer like Device Tree support. This patchset along with DB845c machine driver and WCD934x codec driver has been tested on SDM845 SoC based DragonBoard DB845c with two WSA8810 speakers. Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team. TODO: Add thermal sensor support in WSA881x. Thanks, srini Changes since v5: - updated slave bindings with proper licencing and fixed up examples.

[alsa-devel] [RFC PATCH 0/9] soundwire: add Master device support, GreyBus style
by Pierre-Louis Bossart 18 Sep '19

18 Sep '19

The current use of platform devices leads to limitations in terms of API and problematic reference counts flagged during the review of sysfs patches. As suggested by Greg KH, this patch series introduces a 'Master device' and gets rid of platform devices. The code is inspired by GreyBus, e.g. 'gb_hd_driver' is translated for the SoundWire context as 'sdw_md_driver' and likewise 'gb_host_device' is translated as 'sdw_master_device'. There are differences in the way devices are created, using device_register instead of the multiple steps used in GreyBus. All I know about GreyBus is that it's based on Unipro, so the code updates are based on a first-order analysis, it could very well be I missed concepts while trying to reverse-engineer the code in staging/greybus/. I focused on the concepts mainly and it's also possible that the dual-license for new files or plan-vanilla EXPORT_SYMBOL are not appropriate for all the changes in this series. Please don't take errors as deliberate intent to work-around GPL but rather as an indicator of maturity of the code only developed in the last few days. These changes make it possible to provide new callbacks, e.g splitting the bus startup from the initializations in probe, which is very much desired on Intel platforms to detect the machine driver as early as possible before the hardware is fully powered/enable. These patches will be provided as a separate RFC later today to illustrate the benefit of these changes. To make the code more consistent the first series of patches are renames. I did not rename 'sdw_slave' or 'module_sdw_driver' to avoid compatibility issues since there are codec drivers almost ready for integration. I don't have any specific opinion on if/when additional renames should be done, as long as there is a means to clearly identify what is specific to a SoundWire Master I am fine. Feedback and reviews welcome.

[alsa-devel] RFC: TDM mode support on the tegra30
by Ben Dooks 18 Sep '19

18 Sep '19

This is an initial set that adds support for both the TDM and for formats other than 8/16bit audio through the audio system. It also fixes a minor issue with the FIFO stopping order. I have further patches following on which deal with selection of clocks to allow the use of the tegra's audio unit to run as clock slave (all current examples have the tegra as clock master).
