[alsa-devel] [PATCH v2 0/4] ASoC: codecs: Add WSA881x Smart Speaker amplifier support
by Srinivas Kandagatla 09 Aug '19

09 Aug '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 and module_sdw_driver macro. 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. This patchset also depends on the soundwire Kconfig patch https://lkml.org/lkml/2019/7/18/834 from Pierre Thanks, srini Changes since v1 RFC: - bindings document renamed to slave.txt - fix error code from dt slave parsing Srinivas Kandagatla (4): dt-bindings: soundwire: add slave bindings soundwire: core: add device tree support for slave devices dt-bindings: ASoC: Add WSA881x bindings ASoC: codecs: add wsa881x amplifier support .../bindings/sound/qcom,wsa881x.txt | 27 + .../devicetree/bindings/soundwire/slave.txt | 46 + drivers/soundwire/bus.c | 2 + drivers/soundwire/bus.h | 1 + drivers/soundwire/slave.c | 47 + sound/soc/codecs/Kconfig | 10 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/wsa881x.c | 1160 +++++++++++++++++ 8 files changed, 1295 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/qcom,wsa881x.txt create mode 100644 Documentation/devicetree/bindings/soundwire/slave.txt create mode 100644 sound/soc/codecs/wsa881x.c -- 2.21.0

[alsa-devel] [PATCH] ASoC: hdac_hda: fix page fault issue by removing race
by Pierre-Louis Bossart 08 Aug '19

08 Aug '19

From: Keyon Jie <yang.jie(a)linux.intel.com> There is a race between hda codec device removing and the jack-detecting work, which will lead to a page fault issue as the latter work is accessing codec device which could be already removed. Here add the cancellation of jack-detecting work before codecs are actually removed to avoid the race and fix the issue.
