rproc is a Linuxism. Name it after what the M4 is called.

+NXP iMX6SX/iMX7D Co-Processor Bindings
+----------------------------------------
+
+This binding provides support for ARM Cortex M4 Co-processor found on some
+NXP iMX SoCs.
+
+Required properties:
+- compatible		Should be one of:
+				"fsl,imx7d-rproc"
+				"fsl,imx6sx-rproc"
+- clocks		Clock for co-processor (See: ../clock/clock-bindings.txt)
+- syscon		Phandle to syscon block which provide access to
+			System Reset Controller
+
+Optional properties:
+- memory-region		list of phandels to the reserved memory regions.
+			(See: ../reserved-memory/reserved-memory.txt)
+
+Example:
+	m4_reserved_sysmem1: rproc@80000000 {
+		reg = <0x80000000 0x80000>;
+	};
+
+	m4_reserved_sysmem2: rproc@81000000 {
+		reg = <0x81000000 0x80000>;
+	};
+
+	imx7d-rproc {
+		compatible	= "fsl,imx7d-rproc";
+		memory-region	= <&m4_reserved_sysmem1>, <&m4_reserved_sysmem2>;
+		syscon		= <&src>;
+		clocks		= <&clks IMX7D_ARM_M4_ROOT_CLK>;
+	};
