arm/dts: omap4-sdp: Enable audio support via device tree
On OMAP4 SDP the audio setup includes the twl6040 codec and digital microphones. Since OMAP4 SDP is a reference board it has all possible audio interfaces connected. This information is passed via the ti,audio-routing property. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
