The patch ASoC: rt5682: Add the soundwire support has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 03f6fc6de9192f4e4209ceee0e92f5947d44fc0a Mon Sep 17 00:00:00 2001 From: Oder Chiou <oder_chiou@xxxxxxxxxxx> Date: Wed, 19 Feb 2020 18:28:57 +0800 Subject: [PATCH] ASoC: rt5682: Add the soundwire support This patch adds the soundwire support for ALC5682.
