[alsa-devel] [PATCH 0/9] ASoC: SOF updates for Intel/i.MX
Small set of updates for Intel and NXP platforms.
On the Intel side, the code is now aligned with the HDaudio legacy with the sync_write. OEMs reported concerns with mute LEDs not supported with SOF/UCM, we can now tie a topology-defined control with a mute LED. Note that the large set of differences in the topology is largely due to code move, the new functionality is minimal in size.
On the i.MX side, add topology support for ESAI parameters. This reflects on-going work on the firmware side.
And last add debug module parameters for ACPI and PCI modules. For now the only flag used is for PM runtime, e.g. to measure the suspend-resume latencies of child devices without dealing with DSP reinitialization or keep the parent active while testing the SoundWire clock-stop-mode.

Align SOF HDA implementation with snd-hda-intel driver and enable sync_write flag for all supported Intel platforms in SOF. When set, a sync is issued after each verb write.
Sync after write has helped to overcome intermittent delays in system resume flow on Intel Coffee Lake systems, and most recently probe errors related to the HDMI codec on Ice Lake systems.
Matches the snd-hda-intel driver change done in commit 2756d9143aa5 ("ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips").

This reverts commit 64ca9d9fcb3e3c86b1417e3d17a90b43dd660f81.
The workaround is no longer needed after configuring HDAC bus with sync_write=1.

Introduce sof_ipc_dai_esai_params to keep information that we get from topology and we send to DSP FW.
Also bump the ABI minor to reflect the changes on DSP FW.

From: Daniel Baluta daniel.baluta@nxp.com Date: Tue, 8 Oct 2019 11:44:39 -0500 Subject: [PATCH] ASoC: SOF: imx: Describe ESAI parameters to be sent to DSP
Introduce sof_ipc_dai_esai_params to keep information that we get from topology and we send to DSP FW.
Also bump the ABI minor to reflect the changes on DSP FW.

Currently sof pga element supports only 1 kcontrol and you can't create for example a mixer element with combined volume slider and mute switch. So enable sof pga to have more than 1 kcontrol associated with it. Also check for possible NULL tlv pointer as switch element might not have it.

The patch
AsoC: SOF: refactor control load code
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

From: Jaska Uimonen jaska.uimonen@linux.intel.com
Currently sof doesn't support acpi leds with mute switches. So implement acpi leds following quite shamelessly existing HDA implementation by Takashi Iwai.
Mute leds can be enabled in topology by adding led and direction token in switch control private data.

The patch
ASoC: SOF: acpi led support for switch controls
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

From: Jaska Uimonen jaska.uimonen@linux.intel.com Date: Tue, 8 Oct 2019 11:44:43 -0500 Subject: [PATCH] ASoC: SOF: acpi led support for switch controls
Currently sof doesn't support acpi leds with mute switches. So implement acpi leds following quite shamelessly existing HDA implementation by Takashi Iwai.
Mute leds can be enabled in topology by adding led and direction token in switch control private data.
