[PATCH v2 00/11] Fix support for System Suspend for CS35L41 HDA
by Stefan Binding 28 Jul '23

28 Jul '23

There have been a couple of customer reports of intermittant issues after system resume, where sometimes the DSP firmware stops responding. Investigations into this issue show that there is a race between receiving a prepare from the HDA core, and the firmware reload which is started by the system resume. This can causes the Global Enable on the CS35L41 to be enabled during the firmware load, which can sometimes cause issues in the DSP. The existing system resume behaviour also did not resume the audio, if audio was previously playing when it was suspended. In addition, during investigation, it was found there were additional problems in the System Resume sequence, as well as the Playback sequence with External Boost, where the driver does not correctly follow its enable sequence for this mode. This can cause additional issues such as pops and clicks. This chain intends to correct the sequences for playback and system suspend/resume so that the driver: obeys the external boost enable sequence; resumes audio on system resume; and avoids the race condition on firmware load and playback during system resume. Changes since v1: - Split patch 1 into 2 separate patches - Combine Patches 6 and 9 Stefan Binding (11): ALSA: cs35l41: Use mbox command to enable speaker output for external boost ALSA: cs35l41: Poll for Power Up/Down rather than waiting a fixed delay ALSA: hda: cs35l41: Check mailbox status of pause command after firmware load ALSA: hda: cs35l41: Ensure we correctly re-sync regmap before system suspending. ALSA: hda: cs35l41: Ensure we pass up any errors during system suspend. ALSA: hda: cs35l41: Move Play and Pause into separate functions ALSA: hda: hda_component: Add pre and post playback hooks to hda_component ALSA: hda: cs35l41: Use pre and post playback hooks ALSA: hda: cs35l41: Rework System Suspend to ensure correct call separation ALSA: hda: cs35l41: Add device_link between HDA and cs35l41_hda ALSA: hda: cs35l41: Ensure amp is only unmuted during playback include/sound/cs35l41.h | 5 +- sound/pci/hda/cs35l41_hda.c | 288 +++++++++++++++++++++++++-------- sound/pci/hda/hda_component.h | 2 + sound/pci/hda/patch_realtek.c | 10 +- sound/soc/codecs/cs35l41-lib.c | 118 ++++++++++++-- sound/soc/codecs/cs35l41.c | 18 +-- 6 files changed, 343 insertions(+), 98 deletions(-) -- 2.34.1

[PATCH 0/2] Intel: sof_rt5682: remove quirk flag
by Brent Lu 28 Jul '23

28 Jul '23

We add a helper funcion to detect amplifier number according to device instance in ACPI table so the SOF_MAX98390_TWEETER_SPEAKER_PRESENT flag and a dmi quirk for 4-amplifier configuration could be safely removed. Also refactory the max_98390_hw_params() function to use an array to handle the TDM parameter. Amplifier number detection and TDM parameter are tested on two Chromebooks. One with 2 MAX98390 and one with 4 MAX98390 amplifier. *** BLURB HERE *** Brent Lu (2): ASoC: Intel: maxim-common: get codec number from ACPI ASoC: Intel: sof_rt5682: remove SOF_MAX98390_TWEETER_SPEAKER_PRESENT flag sound/soc/intel/boards/sof_maxim_common.c | 174 +++++++++++++--------- sound/soc/intel/boards/sof_maxim_common.h | 21 ++- sound/soc/intel/boards/sof_rt5682.c | 37 +---- 3 files changed, 115 insertions(+), 117 deletions(-) -- 2.34.1

[RFC v2 00/11] iio: add iio backend device type
by Olivier Moysan 27 Jul '23

27 Jul '23

This v2 is an addon to initial RFC: https://lore.kernel.org/lkml/20230623140944.2613002-1-olivier.moysan@foss.s… Despite the "IIO backend" naming has to be changed (as pointed out by Jonathan previously), it has been kept here, for time being. The appropriated naming still has to be discussed later on. In the previous RFC the "IIO backend" concept was proposed through a set of template APIs. This v2 implements a functionnal exemple based on STM32 DFSDM, to bring scaling support to this peripheral.
