-Macronix NANDs Device Tree Bindings
------------------------------------
-
-Macronix NANDs support randomizer operation for scrambling user data,
-which can be enabled with a SET_FEATURE. The penalty when using the
-randomizer are subpage accesses prohibited and more time period needed
-for program operation, i.e., tPROG 300us to 340us (randomizer enabled).
-Enabling the randomizer is a one time persistent and non reversible
-operation.
-
-For more high-reliability concern, if subpage write is not available
-with hardware ECC and not enabled at UBI level, then enabling the
-randomizer is recommended by default by adding a new specific property
-in children nodes.
-
-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;
-		};
-	};

+title: Macronix NAND Randomizer OTP Enable Property

+
+description:
+  Macronix NAND chips support an optional one-time programmable (OTP)
+  data randomizer that scrambles user data to improve reliability.
+  Enabling it is irreversible, prohibits subpage accesses, and slightly
+  increases program time. This property requests the driver to enable
+  the randomizer if not already set.
+
+properties:
+  mxic,enable-randomizer-otp:
+    type: boolean
+    description:
+      Presence of this property indicates that the data randomizer should
+      be enabled in OTP mode on the NAND chip.
+
+unevaluatedProperties: false
+
+examples:
+  - |
+    nand-controller {
+        #address-cells = <1>;
+        #size-cells = <0>;
+
+        nand@0 {
+            reg = <0>;
+            mxic,enable-randomizer-otp;
+        };
+    };
