ASoC: SOF: Intel: start SoundWire links earlier for LNL+ devices

2024-02-13T13:28:59Z

The SoundWire integration is different from previous platforms, with no dependencies on the DSP enablement. We can start the SoundWire links in the probe instead of waiting for the post_fw_run stage.

ASoC: SOF: Intel: hda: add 'is_chain_dma_supported' callback

2024-02-13T13:28:53Z

Reuse existing function to get the interface mask and expose it to the SOF core with a callback - the main user is the IPC4 topology so only HDaudio platforms provide this callback.

ASoC: SOF: Intel: Use existing helpers to change GPROCEN and PIE bits

2023-11-27T13:44:08Z

Instead of directly changing the GPROCEN/PIE bits in PPCTL we should use the existing helper hda_dsp_ctrl_ppcap_enable() and hda_dsp_ctrl_ppcap_int_enable() helpers for clarity.

ASoC: SOF: Make return of remove_late void, too

2023-10-25T06:38:35Z

Like the change we've done for remove callback, the newly introduced remove_late callback should be changed to void return, too.

Merge tag 'asoc-v6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2023-10-21T07:49:15Z

ASoC: Updates for v6.7 This is quite a large set of changes but mostly due to API cleanups and in driver specific ways rather than due to anything subsystem wide. Highlights include: - Standardisation of API prefixes on snd_soc_, removing asoc_. - GPIO API usage improvements. - Support for HDA patches. - Lots of work on SOF, including crash dump support. - Support for AMD platforms with es83xx, Awinc AT87390, many Intel platforms, many Mediatek platforms, Qualcomm SM6115, Richtek RTQ9128 and Texas Instruments TAS575x.

ASoC: SOF: Intel: Move binding to display driver outside of deferred probe

2023-10-19T12:56:20Z

Now that we can use -EPROBE_DEFER, it's no longer required to spin off the snd_hdac_i915_init into a workqueue. Use the -EPROBE_DEFER mechanism instead, which must be returned in the probe function. The previously added probe_early can be used for this, and we also use the newly added remove_late for unbinding afterwards.

ASoC: SOF: Intel: Fix error handling in hda_init()

2023-10-19T12:54:49Z

The hda_codec_i915_init() errors are ignored in hda_init() so it can never return -EPROBE_DEFER. Fix this before we move the call to hda_init() from the deferred probe to early probe. While at it, also fix error handling when hda_dsp_ctrl_get_caps fails.

ASoC: SOF: Intel: hda: start splitting the probe

2023-10-19T12:54:33Z

This patch moves the initial parts of the probe to the probe_early() callback, which provides a much faster decision on whether the SOF driver shall deal with a specific platform or yield to other Intel drivers. This is a limited functionality change, the bigger change is to move the i915/Xe initialization to the probe_early().

ASoC: SOF: ipc4/Intel: Support for firmware exception

2023-09-19T17:22:11Z

Merge series from Peter Ujfalusi : When a firmware crashes it creats a panic information into a telemetry slot. The panic format is defined by Zephyr, includes stack and additional information to help to identify the reason for the crash. Part of the firmware exception handling the firmware also sends an EXCEPTION_CAUGHT notification. This series implements the kernel side handling of the exception: print information into the kernel log export the whole telemetry slot to user space for tools extract additional information from the panic dump.
