ASoC: SOF: Intel: Initialize chip in hda_sdw_check_wakeen_irq()

2023-08-09T23:27:23+00:00

Clang warns (or errors with CONFIG_WERROR): sound/soc/sof/intel/hda.c:423:6: error: variable 'chip' is uninitialized when used here [-Werror,-Wuninitialized] 423 | if (chip && chip->check_sdw_wakeen_irq) | ^~~~ sound/soc/sof/intel/hda.c:418:39: note: initialize the variable 'chip' to silence this warning 418 | const struct sof_intel_dsp_desc *chip; | ^ | = NULL 1 error generated. Add the missing initialization, following the pattern of the other irq functions.

ASoC: SOF: Intel: add LunarLake support

2023-08-08T12:28:53+00:00

Merge series from Pierre-Louis Bossart : This patchset first fixes a number of errors made in the hda-mlink support, then adds Lunar Lake definitions. The main contribution is the hda-dai changes where the HDaudio DMA is now used for SSP, DMIC and SoundWire. In previous hardware the GPDMA (aka DesignWare) was used and controlled by the audio firmware. The volume of code is minimized with the abstraction added in previous kernel cycles. Due to cross-dependencies between ASoC and SoundWire trees, the full support for jack detection will be deferred to the next kernel cycle. There's not much point to ask for a sync of the two trees to support one patch for each tree - we are at -rc5 already.

ASoC: SOF: Intel: add abstraction for SoundWire wake-ups

The existing code cannot work for LunarLake, let's add a layer of abstraction. No functional change in this patch.

ASoC: SOF: Intel: fix SoundWire/HDaudio mutual exclusion

2023-06-07T11:37:19+00:00

The functionality described in Commit 61bef9e68dca ("ASoC: SOF: Intel: hda: enforce exclusion between HDaudio and SoundWire") does not seem to be properly implemented with two issues that need to be corrected. a) The test used is incorrect when DisplayAudio codecs are not supported. b) Conversely when only Display Audio codecs can be found, we do want to start the SoundWire links, if any. That will help add the relevant topologies and machine descriptors, and identify cases where the SoundWire information in ACPI needs to be modified with a quirk.
