[PATCH 00/10] Add cs42l43 PC focused SoundWire CODEC
by Charles Keepax 19 May '23

19 May '23

This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC. Some supporting work is included in the chain, including adding an ASoC control notification helper function and adding support for IRQs generated by the in-band SoundWire alert mechanism. The chain is currently based of v6.4-rc1 because I am not 100% sure which tree we want to send everything through. The CODEC support has a build dependency on both the SoundWire change and the ASoC soc-component change.

[PATCH 0/3] ASoC: cs35l56: Bugfixes and efficiency improvement
by Richard Fitzgerald 19 May '23

First two patches are bugfixes. Third patch skips the overhead of rebooting the amp after applying firmware files when we know that it isn't necessary.

[PATCH] ASoC: soc-pcm: test if a BE can be prepared
by Pierre-Louis Bossart 19 May '23

19 May '23

From: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> In the BE hw_params configuration, the existing code checks if any of the existing FEs are prepared, running, paused or suspended - and skips the configuration in those cases. This allows multiple calls of hw_params which the ALSA state machine supports. This check is not handled for the prepare stage, which can lead to the same BE being prepared multiple times. This patch adds a check similar to that of the hw_params, with the main difference being that the suspended state is allowed: the ALSA state machine allows a transition from suspended to prepared with hw_params skipped. This problem was detected on Intel IPC4/SoundWire devices, where the BE dailink .prepare stage is used to configure the SoundWire stream with a bank switch. Multiple .prepare calls lead to conflicts with the .trigger operation with IPC4 configurations. This problem was not detected earlier on Intel devices, HDaudio BE dailinks detect that the link is already prepared and skip the configuration, and for IPC3 devices there is no BE trigger.

[PATCH v2 0/7] Add Chameleon v3 ASoC audio
by Paweł Anikiel 19 May '23

19 May '23

The Google Chameleon v3 is a device made for testing audio and video paths of other devices. This patchset adds support for ASoC audio on this device. It has two audio sources: HDMI audio from the it68051 chip (RX only), and analog audio from the ssm2603 chip (RX and TX). The patchset adds the ASoC platform and codec drivers, as well as some changes to the existing ssm2602 codec driver. v2 changes: * Replace chv3-audio machine driver with simple-audio-card * Use regmap_register_patch() in ssm2602 workaround * Remove ssm2602 mute gpio patch, add a gpio hog instead * Simplify hw_pointer logic in chv3-i2s * Commit splits & other misc changes Paweł Anikiel (7): ASoC: Add Google Chameleon v3 i2s driver ASoC: Add Google Chameleon v3 codec driver ASoC: dt-bindings: Add Google Chameleon v3 i2s device ASoC: dt-bindings: Add Google Chameleon v3 audio codec ARM: dts: chameleonv3: Add mute gpio hog ARM: dts: chameleonv3: Add Chameleon v3 audio ASoC: ssm2602: Add workaround for playback distortions .../bindings/sound/google,chv3-codec.yaml | 31 ++ .../bindings/sound/google,chv3-i2s.yaml | 44 +++ .../boot/dts/socfpga_arria10_chameleonv3.dts | 62 ++++ sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/codecs/Kconfig | 8 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/chv3-codec.c | 41 +++ sound/soc/codecs/ssm2602.c | 15 + sound/soc/google/Kconfig | 6 + sound/soc/google/Makefile | 2 + sound/soc/google/chv3-i2s.c | 338 ++++++++++++++++++ 12 files changed, 551 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/google,chv3-codec.yaml create mode 100644 Documentation/devicetree/bindings/sound/google,chv3-i2s.yaml create mode 100644 sound/soc/codecs/chv3-codec.c create mode 100644 sound/soc/google/Kconfig create mode 100644 sound/soc/google/Makefile create mode 100644 sound/soc/google/chv3-i2s.c -- 2.40.1.521.gf1e218fcd8-goog

[PATCH] SoC: rt5682: Disable jack detection interrupt during suspend
by Matthias Kaehlcke 18 May '23

18 May '23

The rt5682 driver switches its regmap to cache-only when the device suspends and back to regular mode on resume. When the jack detect interrupt fires rt5682_irq() schedules the jack detect work. This can result in invalid reads from the regmap in cache-only mode if the work runs before the device has resumed: [ 56.245502] rt5682 9-001a: ASoC: error at soc_component_read_no_lock on rt5682.9-001a for register: [0x000000f0] -16 Disable the jack detection interrupt during suspend and re-enable it on resume. The driver already schedules the jack detection work on resume, so any state change during suspend is still handled. This is essentially the same as commit f7d00a9be147 ("SoC: rt5682s: Disable jack detection interrupt during suspend") for the rt5682s.
