From 6ff67ccafdf4c782489de1ccc47e1ec8d8480b63 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Thu, 3 Nov 2016 01:05:32 +0800 Subject: 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.
