+Renesas RCar r8a779x reset module
+-----------------------------------------------------
+This binding defines the reset module found on Renesas RCar r8a779x
+SoCs. The reset module contains several reset related registers,
+the meaning of them is implementation dependent.
+
+Required properties:
+- compatible : "renesas,rcar-rst"
+- reg : Location and size of the reset module
+
+Example:
+ reset-controller@e6160000 {
+ compatible = "renesas,rcar-rst";
+ reg = <0 0xe6160000 0 0x200>;
+ };
