+* Renesas R-Car Color Management Module (CMM)
+
+Renesas R-Car image enhancement module connected to R-Car DU video channels.
+
+Required properties:
+ - compatible: shall be one of:
+   - "renesas,rcar-gen3-cmm"
+   - "renesas,rcar-gen2-cmm"
+
+ - reg: the address base and length of the memory area where CMM control
+   registers are mapped to.
+
+ - clocks: phandle and clock-specifier pair to the CMM functional clock
+   supplier.
+
+Example:
+--------
+
+	cmm0: cmm@fea40000 {
+		compatible = "renesas,rcar-gen3-cmm";
+		reg = <0 0xfea40000 0 0x1000>;
+		power-domains = <&sysc R8A7796_PD_ALWAYS_ON>;
+		clocks = <&cpg CPG_MOD 711>;
+		resets = <&cpg 711>;
+	};
