+title: NVMEM layout of the Kontron SMARC-sAL28 vital product data
+
+maintainers:
+  - Michael Walle <michael@walle.cc>
+
+description:
+  The vital product data (VPD) of the sl28 boards contains a serial
+  number and a base MAC address. The actual MAC addresses for the
+  on-board ethernet devices are derived from this base MAC address by
+  adding an offset.
+
+properties:
+  compatible:
+    items:
+      - const: kontron,sl28-vpd
+      - const: user-otp
+
+  serial-number:
+    type: object
+
+  base-mac-address:
+    type: object
+
+    properties:
+      "#nvmem-cell-cells":
+        const: 1
+
+required:
+  - compatible
+
+additionalProperties: false
+
+examples:
+  - |
+      otp-1 {
+          compatible = "kontron,sl28-vpd", "user-otp";
+
+          serial_number: serial-number {
+          };

+          base_mac_address: base-mac-address {
+              #nvmem-cell-cells = <1>;
