From 474b62d6eee733abdcd36f8e3e5ce504fbb9110b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 18 Jan 2011 16:14:44 +0000 Subject: ASoC: Provide per widget type callback when executing DAPM sequences Many modern devices have features such as DC servos which take time to start. Currently these are handled by per-widget events but this makes it difficult to paralleise operations on multiple widgets, meaning delays can end up being needlessly serialised. By providing a callback to drivers when all widgets of a given type have been handled during a DAPM sequence the core allows drivers to start operations separately and wait for them to complete much more simply.
