BGRSB-RPMSG : bgrsb-rpmsg is used as an interface between

BG-RSB and Blackghost for Glink communication. bg-rsb is

used to communicate with Blackghost over Glink to

configure the RSB events.



Required properties:

- compatible : should be "qcom,bgrsb-rpmsg"

- glink-channels : RSB_CTRL

- glinkpkt-edge : bg

- intents : <0x200 20>



Example:

	qcom,bg-rsb {

		compatible = "qcom,bgrsb-rpmsg";

		qcom,glink-channels = "RSB_CTRL";

		qcom,glinkpkt-edge = "bg";

		intents = <0x200 20>;

	};
