+* NXP LPC18xx OTP memory

+Internal OTP (One Time Programmable) memory for NXP LPC18xx/43xx devices.
+
+Required properties:
+  - compatible: Should be "nxp,lpc1850-otp"
+  - reg: Must contain an entry with the physical base address and length
+    for each entry in reg-names.

quoted

+  - address-cells: must be set to 1.
+  - size-cells: must be set to 1.

Not needed unless you have child nodes.

They will have "nvmem" cell children. See patch 3/3

+                       /* Flashless devices has part ID in OTP bank 0 */
+                       part_id: identification@0 {
+                               reg = <0x0 0x10>;
+                       };

These cells are documented in nvmem.txt.
