= 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";
qcom,intents = <0x2000 2>;
reg = <GPR_DOMAIN_ADSP>;
cdev_name = "nongpr_channel";
cc_codec: qcom,cc-codec {
compatible = "qcom, cc-codec";
};
};
