= 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

	Value type: <stringlist>

	Definition: must be "qcom,cc-codec"



= EXAMPLE

The following example represents the audio-cc-ipc node having a codec child node



	audio_ipc1: qcom,audio_cc_ipc1 {

		compatible = "qcom,audio_cc_ipc";

		qcom,glink-channels = "custom_cc_apps";

		reg = <GPR_DOMAIN_ADSP>;

		cdev_name = "nongpr_channel";



		cc_codec: qcom,cc-codec {

			compatible = "qcom, cc-codec";

		};
