+Macronix NANDs Device Tree Bindings
+-----------------------------------
+
+Macronix NANDs support randomizer operation for user data scrambled,
+which can be enabled with a SET_FEATURE. The penalty of randomizer
+is subpage accesses prohibited. By adding a new specific property
+in children nodes to enable randomizer function.
+
+Required NAND chip properties in children mode:
+- randomizer enable: should be "mxic,enable-randomizer-otp"
+
+Example:
+
+	nand: nand-controller@unit-address {
+
+		nand@0 {
+			reg = <0>;
+			mxic,enable-randomizer-otp;
+		};
+	};
