+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>;
+ };
+ };
