* SMCInvoke driver to provide transport between TZ and Linux



Required properties:

- compatible : Should be "qcom,smcinvoke"

- reg : should contain memory region address reserved for loading secure apps.



Example:

	qcom_smcinvoke: smcinvoke@87900000 {

		compatible = "qcom,smcinvoke";

		reg = <0x87900000 0x2200000>;

	};
