From 64a648c2204b0c750fe49828158751183d8b5f83 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Mon, 25 Jul 2011 11:15:15 +0100 Subject: ASoC: dapm - Add DAPM stream completion event. In preparation for Dynamic PCM (AKA DSP) support. This adds a callback function to be called at the completion of a DAPM stream event. This can be used by DSP components to perform calculations based on DAPM graphs after completion of stream events.
