This is an update on an earlier contribution from Heikki Krogerus

The function device_add_properties() is going to be removed. Replacing it with software node API equivalents.

Thanks for Hans de Goede and Andy Shevchenko for their comments, suggestions and Reviewed-by tags on GitHub. The review thread can be found at https://github.com/thesofproject/linux/pull/3041)

v3 changes: Fixed nit-picks from Andy: label, return value, missing commas/periods. Added Andy's Reviewed-by tag

v2 changes: feedback from Andy and Hans Better error handling Codec reference is kept until the .remove callback Remove bus search to find device

v1 changes from Heikki's patches: Avoid the use of devm_ routines for Baytrail machine drivers.

New subject: [PATCH v3 1/8] ASoC: Intel: boards: harden codec property handling

In current ACPI-based devices, the DSDT does not include any of the properties required by the codec driver. This is not an ACPI limitation proper since the _DSD method could be used, as done for Camera and SoundWire in newer platforms. For legacy devices, there is unfortunately no other option than using a work-around: we add properties to the codec device from the machine driver.

To avoid any issues with the codec driver being unbound, we need to keep a reference to the codec device until the card is removed.

New subject: [PATCH v3 2/8] ASoC: Intel: boards: handle errors with acpi_dev_get_first_match_dev()

acpi_dev_get_first_match_dev() searches for an acpi_handle instantiated by the ACPI table scanning done early during boot.

Two of three machine drivers using this search don't deal with errors and the one which does (bytcr_rt5651) returns -ENODEV, which doesn't make sense here: an alternate driver will not be probed.

Add consistent error handling and report -ENXIO.

New subject: [PATCH v3 5/8] ASoC: Intel: sof_sdw_rt711*: keep codec device reference until remove

Follow the example of Intel Atom drivers and keep a reference to the headset codec until the properties are removed.

There is no guarantee that the module for the codec driver is loaded before the machine driver probe, the use of the deferred probe mechanism is required.

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

Thanks for Hans de Goede and Andy Shevchenko for their comments, suggestions and Reviewed-by tags on GitHub. The review thread can be found at https://github.com/thesofproject/linux/pull/3041)

v3 changes: Fixed nit-picks from Andy: label, return value, missing commas/periods. Added Andy's Reviewed-by tag

v2 changes: feedback from Andy and Hans Better error handling Codec reference is kept until the .remove callback Remove bus search to find device

v1 changes from Heikki's patches: Avoid the use of devm_ routines for Baytrail machine drivers.

While sof_sdw_* machine boards history shows these have been updated concurrently, the same cannot be said for other, older Intel boards. And thus, I'd advise to separate changes for each older board, here: bytcht_es8316, bytcr_rt5640 and bytcr_rt5651. You could even squash smaller changes so the number of patches isn't getting out of control.

If regression occurs in just one of them - even due to spelling error or unintended code line - revert will impact all the boards. In the past having separate patches for kbl_*, bdw_* and such saved a lot of trouble, especially given their history.

This is more of an suggestion than a blocker. Haven't found any code issues:
