From: Mengdong Lin Date: Wed, 2 Nov 2016 17:05:32 +0000 (+0800) Subject: ASoC: topology: ABI - Add voice wake up flag for DAI links X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ff67ccafdf4c782489de1ccc47e1ec8d8480b63;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
