[PATCH 0/3] ASoC: SOF: misc fixes
We somehow missed the default path for DSP libraries for LNL, and need to restrict support for D0i3 w/ IPC4. Also add debugfs support for firmware profile information so that sof-test scripts can show what is being tested.

The commit cd6f2a2e6346 ("ASoC: SOF: Intel: Set the default firmware library path for IPC4") added the default_lib_path field for all platforms, but this was missed when LunarLake was later introduced.

From: Ranjani Sridharan ranjani.sridharan@linux.intel.com
Introduce a new field in struct sof_ipc_pcm_ops that can be used to restrict DSP D0i3 during S0ix suspend to IPC3. With IPC4, all streams must be stopped before S0ix suspend.

/**
The SOF driver has multiple profiles to select firmware/topology prefix/names depending on the platform and ipc_type, and each of those fields can be overridden with kernel parameters. This results in some cases in confusion on what configuration is actually used in a given test.
We currently log the firmware and topology names in the kernel logs, but there's been an ask to add the information in debugfs to simplify test scripts used by developers and CI.
This isn't meant to be a stable ABI used by apps, changes will be allowed as needed.

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
