+DT bindings for the Renesas R-Car Reset Controller
+
+The R-Car Reset Controller provides reset control, and implements the following
+functions:
+  - Register-based reset control for the various CPU cores,
+  - Latching of the levels on mode pins when PRESET# is negated,
+  - Mode monitoring register,
+  - Boot address registers for the various CPU cores.
+
+
+Required properties:
+  - compatible: Should be "renesas,<soctype>-rst", and "syscon".
+		Examples with soctypes are:
+		  - "renesas,r8a7790-rst" (R-Car H2)
+		  - "renesas,r8a7791-rst" (R-Car M2-W)
+		  - "renesas,r8a7792-rst" (R-Car V2H
+		  - "renesas,r8a7793-rst" (R-Car M2-N)
+		  - "renesas,r8a7794-rst" (R-Car E2)
+		  - "renesas,r8a7795-rst" (R-Car H3)
+		  - "renesas,r8a7796-rst" (R-Car M3-W)
+  - reg: Address start and address range for the device.
+
+
+Example:
+
+	rst: reset-controller@e6160000 {
+		compatible = "renesas,r8a7795-rst", "syscon";
+		reg = <0 0xe6160000 0 0x0200>;
+	};
