+= AUDIO_CC_IPC_NODE
+Each subnode of the glink_slatecom_xprt is a device node exposed to user space
+by the audio-cc-ipc driver for sending ipc packets between the ipc clients.
+Maximum nodes supported is 2.
+- Each node defined should contain following property
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,audio_cc_ipc"
+
+- qcom,glink-channels:
+	Usage: required
+	Value type: <stringlist>
+
+- reg:
+	Usage: required
+	Value type: <u32>
+
+- cdev_name:
+	Usage: required
+	Value type: <stringlist>
+
+= CC_CODEC_NODE
+Audio_cc_ipc nodes can have a cc_codec child node. This node will act as an
+interface for proxy codec, to manage the communication to its counter part
+through ipc.
+- Each node defined should contain following property
+
+- compatible:
+	Usage: required
