[PATCH -next 0/2] ASoC: Cleanup deprecated regmap-irq functionality
by Aidan MacDonald 28 Aug '22

28 Aug '22

Update two ASoC codec drivers to remove uses of regmap-irq type registers, which have recently been deprecated by the "regmap-irq cleanups and refactoring" series in linux-next.

Request for setup of new repositories
by Takashi Sakamoto 27 Aug '22

27 Aug '22

Hi Jaroslav, Iwai-san, Thanks for your maintenance for alsa-project organization in github.com. Currently I'd like to add new three repositories under the organization as a part of my work for ALSA firewire stack. I've been maintaining libhinawa since 2014 and recently realized that current design is not necessarily convenient since it includes two functions; operation to Linux FireWire cdev, and operation of ALSA HwDep cdev. Currently I'm working for new library to split the latter operation. Then I'd like you to setup below repositories: * 'libhitaki' * 'libhitaki-doc' * 'hitaki-rs' The library itself and its Rust binding are utilized by 'snd-firewire-ctl-services'[2], thus it's preferable to register them under 'GObject Introspection' Team. Thanks for your assist for my work. [1] https://github.com/alsa-project/libhinawa [2] https://github.com/alsa-project/snd-firewire-ctl-services Regards Takashi Sakamoto

[PATCH 1/2] lib/string_helpers: Introduce strsplit_u32()
by Cezary Rojewski 25 Aug '22

25 Aug '22

Add strsplit_u32() and its __user variant to allow for splitting specified string into array of u32 tokens. Originally this functionality was added for the SOF sound driver. As more users are on the horizon, relocate it so it becomes a common good.

[PATCH 1/5] soundwire: sysfs: move sdw_slave_dev_attr_group into the existing list of groups
by Greg Kroah-Hartman 24 Aug '22

24 Aug '22

The sysfs logic already creates a list of groups for the device, so add the sdw_slave_dev_attr_group group to that list instead of having to do a two-step process of adding a group list and then an individual group. This is a step on the way to moving all of the sysfs attribute handling into the default driver core attribute group logic so that the soundwire core does not have to do any of it manually.

[PATCH 0/3] ASoC: SOF: Intel: hda: Correct Firmware State Register use
by Peter Ujfalusi 23 Aug '22

23 Aug '22

Hi, The FSR (Firmware State Register) holds the ROM state information, it does not contain error information. The FSR itself is a bit more complicated as well as the state depends on the module currently in use. The error code from ROM or the status code from the firmware is located at the next register. Fix the handling of the FSR in order to provide usable and human readable (in most cases) report on the status and error. Regards, Peter --- Peter Ujfalusi (3): ASoC: SOF: Intel: hda: Correct the ROM/FW state reporting code ASoC: SOF: Intel: hda-loader: Use the FSR state definitions during bootup ASoC: SOF: Intel: hda: Drop no longer used ROM state definitions sound/soc/sof/intel/hda-loader.c | 10 +-- sound/soc/sof/intel/hda.c | 147 ++++++++++++++++++++++++++----- sound/soc/sof/intel/hda.h | 69 +++++++++++++-- 3 files changed, 194 insertions(+), 32 deletions(-) -- 2.37.0

[PATCH] ASoC: ops: Don't modify the driver's plaform_max when reading state
by Mark Brown 22 Aug '22

22 Aug '22

Currently snd_soc_info_volsw() will set a platform_max based on the limit the control has if one is not already set. This isn't really great, we shouldn't be modifying the passed in driver data especially in a path like this which may not ever be executed or where we may execute other callbacks before this one. Instead make this function leave the data unchanged, and clarify things a bit by referring to max rather than platform_max within the function. platform_max is now applied as a limit after working out the natural maximum value for the control. This means that platform_max is no longer treated as a direct register value for controls were min is non-zero. The put() callbacks already validate on this basis, and there do not appear to be any in tree users that would be affected.

This patch enables the Avid Mbox 3 audio interface to be used through ALSA. It locks the device at a 48khz sample rate.

[PATCH 1/2] ASoC: Intel: Skylake: fix error message of NHLT blob selection
by Icenowy Zheng 18 Aug '22

18 Aug '22

The query to select NHLT blob had been changed to use parameters of the pipeline instead of PCM, however the error message returned when it fails still uses PCM properties. Fix this inconsistency.

[PATCH 0/4] ASoC/soundwire: log actual PING status on resume issues
by Bard Liao 17 Aug '22

17 Aug '22

we've been stuck with problems in the dual-amplifier configurations where one of the two devices seems to become UNATTACHED and never regains sync, see https://github.com/thesofproject/linux/issues/3638. This is a rather infrequent issue that may happen once or twice per month, but still it remains a concern. One possibility is that the device does lose sync but somehow our hardware detection fails to see it resync. This series just adds a basic read directly from the PING frames to help confirm if yes/no the device regain sync. The change is mainly on soundwire. @Mark, Could you ack the ASoC patch if it looks good to you? Pierre-Louis Bossart (4): soundwire: add read_ping_status helper definition in manager ops soundwire: intel/cadence: expose PING status in manager ops soundwire: add sdw_show_ping_status() helper ASoC: codecs: show PING status on resume failures drivers/soundwire/bus.c | 32 ++++++++++++++++++++++++++++++ drivers/soundwire/cadence_master.c | 8 ++++++++ drivers/soundwire/cadence_master.h | 2 ++ drivers/soundwire/intel.c | 1 + include/linux/soundwire/sdw.h | 5 +++++ sound/soc/codecs/max98373-sdw.c | 2 ++ sound/soc/codecs/rt1308-sdw.c | 2 ++ sound/soc/codecs/rt1316-sdw.c | 2 ++ sound/soc/codecs/rt5682-sdw.c | 2 ++ sound/soc/codecs/rt700-sdw.c | 2 ++ sound/soc/codecs/rt711-sdca-sdw.c | 2 ++ sound/soc/codecs/rt715-sdca-sdw.c | 2 ++ sound/soc/codecs/rt715-sdw.c | 2 ++ 13 files changed, 64 insertions(+) -- 2.25.1
