[alsa-devel] [PATCH v7 11/11] ASoC: topology: ABI - Add voice wake up flag for DAI links

[mengdong.lin at linux.intel.com]

From: Mengdong Lin <mengdong.lin at linux.intel.com>

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.
