+- ports: A Codec may have a single or multiple I2S interfaces. These
+  interfaces on Codec side can be described under 'ports' or 'port'.
+  When the SoC or host device is connected to multiple interfaces of
+  the Codec, the connectivity can be described using 'ports' property.
+  If a single interface is used, then 'port' can be used. The usage
+  depends on the platform or board design.
