From 97126ce8ce8d6f023b8ce3b71c3df882a2951605 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Fri, 13 May 2016 16:45:16 +0100 Subject: ASoC: arizona: Add voice trigger output widget In some situations the voice control firmware will by used to only provide a trigger notification event. In this case a compressed stream will not be opened by user-space, as such we need to provide a virtual output to power on the DSP in this use-case. This patch adds a virtual output 'DSP Voice Trigger' that can be used for this, and a switch that lets it be connected to the core when required.
