[alsa-devel] [PATCH] ASoC: Intel: sof_rt5682: Ignore the speaker amp when there isn't one.
by Sam McNally 03 Jan '20

03 Jan '20

Some members of the Google_Hatch family include a rt5682, but not a speaker amp. When a speaker amp is also present, it matches MX98357A as well, resulting in the quirk_data field in the snd_soc_acpi_mach being non-null. When only the rt5682 is present, quirk_data is left null. The sof_rt5682 driver's DMI data matching identifies that a speaker amp is present for all Google_Hatch family devices. Detect cases where there is no speaker amp by checking for a null quirk_data in the snd_soc_acpi_mach and remove the speaker amp bit in that case.

[alsa-devel] topology file broadwell.conf
by Jaroslav Kysela 02 Jan '20

02 Jan '20

Hi all, I am working on some (major) cleanups for the topology library and I hit the issue with the topology file broadwell.conf in upstream. It cannot be compiled with the latest alsatplg / libatopology, because the SectionPCMConfig was removed in commit 368e4f2a897b5500573a2ee525f5504c135cfca2 in alsa-lib. Which driver is using this topology in the current linux kernel? Thanks, Jaroslav -- Jaroslav Kysela <perex(a)perex.cz> Linux Sound Maintainer; ALSA Project; Red Hat, Inc.

[alsa-devel] [PATCH v4 0/2] ASoC: mt8183: fix audio playback slowly after playback
by Jiaxin Yu 02 Jan '20

02 Jan '20

This series patches add reset controller for MT8183, and audio will use it in machine driver during bootup, they depend on the for-next. v4 changes: 1. Fixed wrong signed-off as correct mail suffix. 2. Fixed patch subject that add patch version. v3 changes: 1. https://patchwork.kernel.org/patch/11164283/ and https://patchwork.kernel.org/patch/11164305/ has been merged. 2. Change the name of mtk_wdt_compatible to mtk_wdt_data. 3. Remove toprgu_reset struct and use mtk_wdt_dev instead. 4. Get the value of sw_rst_num from .h file. 5. Adddd mt2712-resets.h for mt2712. 6. Improve commit message. v2 changes: 1. remove "WIP" that in the title of patches 2. add hyper link for the patch that depends on 3. patchwork list: https://patchwork.kernel.org/cover/11164285/ https://patchwork.kernel.org/patch/11164295/ https://patchwork.kernel.org/patch/11164299/ https://patchwork.kernel.org/patch/11164283/ https://patchwork.kernel.org/patch/11164305/ v1 changes: 1. patchwork list: https://patchwork.kernel.org/cover/11164173/ https://patchwork.kernel.org/patch/11164181/ https://patchwork.kernel.org/patch/11164185/ https://patchwork.kernel.org/patch/11164187/ https://patchwork.kernel.org/patch/11164175/ yong.liang (2): dt-bindings: mediatek: mt8183: Add #reset-cells watchdog: mtk_wdt: mt8183: Add reset controller .../devicetree/bindings/watchdog/mtk-wdt.txt | 10 +- drivers/watchdog/Kconfig | 1 + drivers/watchdog/mtk_wdt.c | 111 +++++++++++++++++- .../reset-controller/mt2712-resets.h | 22 ++++ .../reset-controller/mt8183-resets.h | 15 +++ 5 files changed, 155 insertions(+), 4 deletions(-) create mode 100644 include/dt-bindings/reset-controller/mt2712-resets.h -- 2.18.0
