+DT bindings for the Renesas RZ/N1 System Controller
+
+== System Controller Node ==
+
+The system controller node currently only hosts a single sub-node to handle
+the rebooting of the CPU. Eventually it will host the clock driver, SMP
+start handler, watchdog etc.
+
+See renesas,rzn1-reboot.txt for further details.
+
+Bindings:
++ Required:
+	compatible = "renesas,r9a06g032-sysctrl",
+			"renesas,rzn1-sysctrl",
+			"syscon", "simple-mfd";
+
+Example:
+	sysctrl: sysctrl at 4000c000 {
+		compatible = "renesas,r9a06g032-sysctrl",
+				"renesas,rzn1-sysctrl",
+				"syscon", "simple-mfd";
+		reg = <0x4000c000 0x1000>;
+	};
