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 >From af78cec45f2d01be9d14c177e403c8021ebfd40e Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Date: Mon, 16 Sep 2019 16:42:40 -0500 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.
