From 47eee072bf90374ce98a15668e6b450de313100a Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Fri, 23 Feb 2018 21:02:54 +0100 Subject: [PATCH] ARM: dts: omap4-droid4: add soundcard Add sound support to Motorola Droid 4 using simple-soundcard and CPCAP's audio codec. This does not yet correctly represent the whole audio routing, since McBSP3 is also connected to Bluetooth and MDM6600 modem (and probably also 4G modem). These extra DAI links are not yet supported and have not been tested.
