From d35eb96a95dc82befe2d9d1533728506b0847f14 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Thu, 17 Dec 2015 20:35:45 -0600 Subject: [PATCH] ASoC: Intel: boards: add DEEP_BUFFER support for BYT/CHT/BSW Add dai links to enable additional playback stream with deeper buffer for lower power consumption. The normal and DEEP_buffer streams are not mutually exclusive, content will be mixed by the DSP.
