[PATCH v2 0/3] ASoC: SOF: Fixes for suspend after firmware crash
by Peter Ujfalusi 20 Dec '22

20 Dec '22

Hi, This is the followup series for the v1 sent out by Ranjani [1]. Unfortunately Ranjani was dragged away to another issue and could not send the update herself. Changes since v1: - In patch 2, move the tear_down_all_pipelines call instead of duplicating it Amadeusz: I have kept the check as it is: if (tplg_ops && tplg_ops->tear_down_all_pipelines) I'm preparing the ops optionality change series which would require this change.

[PATCH 0/2] ASoC: SOF: remove unregister calls from shutdown
by Kai Vehmanen 20 Dec '22

20 Dec '22

This patchset is an alternative solution to problems reported by Ricardo Ribalda <ribalda(a)chromium.org> and Zhen Ni <nizhen(a)uniontech.com>, as discussed in - "[PATCH] ALSA: core: Fix deadlock when shutdown a frozen userspace" https://mailman.alsa-project.org/pipermail/alsa-devel/2022-November/209248.… - "[PATCH] ASoc: SOF: Fix sof-audio-pci-intel-tgl shutdown timeout during hibernation" https://mailman.alsa-project.org/pipermail/alsa-devel/2022-December/209685.… It was raised by Oliver Neukum <oneukum(a)suse.com> that kernel should not let user-space stall the shutdown process in any scenario and the unregister call in current SOF shutdown code is not right. This series reverts the ASoC SOF patch to unregister clients and the machine drivers at shutdown. To avoid bringing back old bugs, the series includes a patch to fix S5 entry on certain Intel platforms.

My question is, **is it possible to specify the rate limitation in a** `SectionDevice` ? I checked the alsa-ucm-conf documentation and did not find any section for this :/ [alsa-ucm-conf docs](https://www.alsa-project.org/alsa-doc/alsa-lib/group__ucm__conf.htmll) Thanks a bunch !

by Trevor Wu 19 Dec '22

19 Dec '22

This series of patches adds support for Mediatek AFE of MT8188 SoC. Patches are based on broonie tree "for-next" branch. Changes since v2: - drop CLK_IGNORE_UNUSED flag - include bitfield.h to reslove the issue reported by kernel test robot - rename mt8188-afe-pcm.yaml to mt8188-afe.yaml - refine dt-binding files based on reviewer's suggestions Changes since v1: - remove bus protection functions in case of unmerged dependency problem - replace some bit operation macro with FIELD_PREP - simplify register control by regmap_set_bits and regmap_clear_bits - fix dt-binding errors - rename compatible string for recognition Trevor Wu (12): ASoC: mediatek: common: add SMC ops and SMC CMD ASoC: mediatek: mt8188: add common header ASoC: mediatek: mt8188: support audsys clock ASoC: mediatek: mt8188: support adda in platform driver ASoC: mediatek: mt8188: support etdm in platform driver ASoC: mediatek: mt8188: support pcmif in platform driver ASoC: mediatek: mt8188: support audio clock control ASoC: mediatek: mt8188: add platform driver ASoC: mediatek: mt8188: add control for timing select dt-bindings: mediatek: mt8188: add audio afe document ASoC: mediatek: mt8188: add machine driver with mt6359 dt-bindings: mediatek: mt8188: add mt8188-mt6359 document .../devicetree/bindings/sound/mt8188-afe.yaml | 196 + .../bindings/sound/mt8188-mt6359.yaml | 60 + sound/soc/mediatek/Kconfig | 23 + sound/soc/mediatek/Makefile | 1 + sound/soc/mediatek/common/mtk-base-afe.h | 19 + sound/soc/mediatek/mt8188/Makefile | 15 + sound/soc/mediatek/mt8188/mt8188-afe-clk.c | 656 ++++ sound/soc/mediatek/mt8188/mt8188-afe-clk.h | 114 + sound/soc/mediatek/mt8188/mt8188-afe-common.h | 151 + sound/soc/mediatek/mt8188/mt8188-afe-pcm.c | 3359 +++++++++++++++++ sound/soc/mediatek/mt8188/mt8188-audsys-clk.c | 205 + sound/soc/mediatek/mt8188/mt8188-audsys-clk.h | 15 + .../soc/mediatek/mt8188/mt8188-audsys-clkid.h | 83 + sound/soc/mediatek/mt8188/mt8188-dai-adda.c | 632 ++++ sound/soc/mediatek/mt8188/mt8188-dai-etdm.c | 2591 +++++++++++++ sound/soc/mediatek/mt8188/mt8188-dai-pcm.c | 367 ++ sound/soc/mediatek/mt8188/mt8188-mt6359.c | 808 ++++ sound/soc/mediatek/mt8188/mt8188-reg.h | 3180 ++++++++++++++++ 18 files changed, 12475 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/mt8188-afe.yaml create mode 100644 Documentation/devicetree/bindings/sound/mt8188-mt6359.yaml create mode 100644 sound/soc/mediatek/mt8188/Makefile create mode 100644 sound/soc/mediatek/mt8188/mt8188-afe-clk.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-afe-clk.h create mode 100644 sound/soc/mediatek/mt8188/mt8188-afe-common.h create mode 100644 sound/soc/mediatek/mt8188/mt8188-afe-pcm.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-audsys-clk.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-audsys-clk.h create mode 100644 sound/soc/mediatek/mt8188/mt8188-audsys-clkid.h create mode 100644 sound/soc/mediatek/mt8188/mt8188-dai-adda.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-dai-etdm.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-dai-pcm.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-mt6359.c create mode 100644 sound/soc/mediatek/mt8188/mt8188-reg.h -- 2.18.0
