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. Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
