[Sound-open-firmware] [PATCH AUTOSEL 6.1 03/53] ASoC: SOF: pm: Always tear down pipelines before DSP suspend
by Sasha Levin 16 Jan '23

16 Jan '23

From: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> [ Upstream commit d185e0689abc98ef55fb7a7d75aa0c48a0ed5838 ] When the DSP is suspended while the firmware is in the crashed state, we skip tearing down the pipelines. This means that the widget reference counts will not get to reset to 0 before suspend. This will lead to errors with resuming audio after system resume. To fix this, invoke the tear_down_all_pipelines op before skipping to DSP suspend.

[Sound-open-firmware] [PATCH AUTOSEL 6.1 02/53] ASoC: SOF: pm: Set target state earlier
by Sasha Levin 16 Jan '23

From: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> [ Upstream commit 6f95eec6fb89e195dbdf30de65553c7fc57d9372 ] If the DSP crashes before the system suspends, the setting of target state will be skipped because the firmware state will no longer be SOF_FW_BOOT_COMPLETE. This leads to the incorrect assumption that the DSP should suspend to D0I3 instead of suspending to D3. To fix this, set the target_state before we skip to DSP suspend even when the DSP has crashed.

[Sound-open-firmware] [PATCH] ASoC: SOF: sof-audio: Check snd_sof_widget pointer not NULL

[Sound-open-firmware] [PATCH 00/15] ASoC: Drop empty platform remove functions
by Uwe Kleine-König 27 Dec '22

27 Dec '22

From: Uwe Kleine-König <uwe(a)kleine-koenig.org> Hello, this patch series removes all platform remove functions that only return zero below sound/soc. There is no reason to have these, as the only caller is platform core code doing: if (drv->remove) { int ret = drv->remove(dev); ... } (in platform_remove()) and so having no remove function is both equivalent and simpler. Best regards Uwe Uwe Kleine-König (15): ASoC: pxa: Drop empty platform remove function ASoC: amd: Drop empty platform remove function ASoC: atmel-classd: Drop empty platform remove function ASoC: atmel-pdmic: Drop empty platform remove function ASoC: 88pm860x: Drop empty platform remove function ASoC: ac97: Drop empty platform remove function ASoC: adau7002: Drop empty platform remove function ASoC: bt-sco: Drop empty platform remove function ASoC: cq93vc: Drop empty platform remove function ASoC: mc13783: Drop empty platform remove function ASoC: wl1273: Drop empty platform remove function ASoC: pxa: e740_wm9705: Drop empty platform remove function ASoC: pxa: e750_wm9705: Drop empty platform remove function ASoC: pxa: e800_wm9712: Drop empty platform remove function ASoC: SOF: nocodec: Drop empty platform remove function sound/soc/amd/raven/acp3x-i2s.c | 8 -------- sound/soc/atmel/atmel-classd.c | 6 ------ sound/soc/atmel/atmel-pdmic.c | 6 ------ sound/soc/codecs/88pm860x-codec.c | 6 ------ sound/soc/codecs/ac97.c | 6 ------ sound/soc/codecs/adau7002.c | 6 ------ sound/soc/codecs/bt-sco.c | 6 ------ sound/soc/codecs/cq93vc.c | 6 ------ sound/soc/codecs/mc13783.c | 6 ------ sound/soc/codecs/wl1273.c | 6 ------ sound/soc/pxa/e740_wm9705.c | 6 ------ sound/soc/pxa/e750_wm9705.c | 6 ------ sound/soc/pxa/e800_wm9712.c | 6 ------ sound/soc/pxa/spitz.c | 6 ------ sound/soc/sof/nocodec.c | 6 ------ 15 files changed, 92 deletions(-) base-commit: 3a28c2c89f4b412b648761430720d40a8dc326ef -- 2.38.1
