changes since v1:
- add custom select
- add description
- add "additionalProperties: false", I wasn't sure if all the
subnodes needs it. I'd say yes, but the brcm,nvram binding
doesn't have them neither.

+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.
+
+# We need a select here so we don't match all nodes with 'user-otp'
+select:
+ properties:
+ compatible:
+ contains:
+ const: kontron,sl28-vpd
+ required:
+ - compatible
+
+properties:
+ compatible:
+ items:
+ - const: kontron,sl28-vpd
+ - const: user-otp
+
+ serial-number:
+ type: object
+ description: The board's serial number
+
+ base-mac-address:
+ type: object
+ description:
+ Base MAC address for all on-module network interfaces. The first
+ argument of the phandle will be treated as an offset.
+
+ properties:
+ "#nvmem-cell-cells":
+ const: 1
+
+ additionalProperties: false
+
+required:
+ - compatible
+
+additionalProperties: false
