From 769d3be463ba1fe1cf7ef8b59e8e969e00cd7efc Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 15 Feb 2019 13:04:22 +0100 Subject: ASoC: samsung: odroid: Add missing DAPM routes With old DTS there will be missing DAPM routes linking BE with CODECs. Add those routes in the card driver so sound works properly on Odroid XU3/4 also without DTS updates enabling the secondary PCM.
