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. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Signed-off-by: Tony Lindgren <tony@atomide.com>
