The patch ASoC: topology: ABI - Add voice wake up flag for DAI links has been applied to the asoc tree at git://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 6ff67ccafdf4c782489de1ccc47e1ec8d8480b63 Mon Sep 17 00:00:00 2001 From: Mengdong Lin <mengdong.lin@xxxxxxxxxxxxxxx> Date: Thu, 3 Nov 2016 01:05:32 +0800 Subject: [PATCH] ASoC: topology: ABI - Add voice wake up flag for DAI links Add a new flag bit SND_SOC_TPLG_LNK_FLGBIT_VOICE_WAKEUP to link flags. If a link is used for voice wake up, users can set this flag bit and topology will set the link's 'ignore_suspend' to true. This ABI update is backward compatible.
