-Required properties:
-
-  - compatible         : "fsl,imx-audio-sgtl5000"
-
-  - model              : The user-visible name of this sound complex

-  - audio-codec                : The phandle of the SGTL5000 audio codec
-
-  - audio-routing      : A list of the connections between audio components.
-                         Each entry is a pair of strings, the first being the
-                         connection's sink, the second being the connection's
-                         source. Valid names could be power supplies, SGTL5000
