Optional properties:
-qcom,xprt : The name of the transport on which to notify this subystem.
-qca,no-notify-edges : specifies that no other subsystems needs to be notified

Example:

	glink_mpss: qcom,glink-ssr-modem {

		label = "q6v5-wcss";
		qcom,edge = "mpss";
		qca,no-notify-edges;
		qcom,xprt = "smem";
	};

	glink_mpss: qcom,glink-ssr-modem {
		compatible = "qcom,glink_ssr";
		label = "modem";
		qcom,edge = "mpss";
		qcom,notify-edges = <&glink_adsp>, <&glink_wcnss>;
		qcom,xprt = "smem";
	};

	glink_adsp: qcom,glink-ssr-adsp {
		compatible = "qcom,glink_ssr";
		label = "adsp";
		qcom,edge = "adsp";
		qcom,notify-edges = <&glink_mpss>, <&glink_wcnss>;
	};
