From 356caf663deee8dc46ff3168ec0b24bcbeb00b28 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 8 Jun 2023 06:48:36 +0000 Subject: ASoC: add new trigger ordering method Current ASoC is assuming that trigger starting order is Link -> Component -> DAI as default, and its reverse order for stopping. But some Driver / Card want to reorder it for some reasons. We have such flags, but is unbalance like below. struct snd_soc_component_driver :: start_dma_last struct snd_soc_dai_link :: stop_dma_first We want to have more flexible, and more generic method. This patch adds new snd_soc_trigger_order for start/stop at component / DAI-link.
