Subject: Applied "ASoC: soc-acpi: add link_mask field" to the asoc tree

The patch

   ASoC: soc-acpi: add link_mask field

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

Subject: [PATCH] ASoC: soc-acpi: add link_mask field

When interfaces can be pin-muxed, static information from ACPI might
not be enough. Add information on which links needs to be enabled by
hardware/firmware for a specific machine driver to be selected.

When walking through the list of possible machines, links will be
checked, which implies that configurations where multiple links are
required need to be checked first.

Additional criteria will be needed later, such as which SoundWire
Slave devices are actually enabled, but for now this helps detect
between basic configurations.
