Subject: [PATCH v2 15/20] dt-bindings: nvmem: add YAML schema for the sl28 vpd layout
Date: Fri,  2 Sep 2022 00:18:52 +0200	[thread overview]
Message-ID: <20220901221857.2600340-16-michael@walle.cc> (raw)
In-Reply-To: <20220901221857.2600340-1-michael@walle.cc>

Add a schema for the NVMEM layout on Kontron's sl28 boards.

Signed-off-by: Michael Walle <michael@walle.cc>
---
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
+
+examples:
+  - |
+      otp-1 {
+          compatible = "kontron,sl28-vpd", "user-otp";
+
+          serial_number: serial-number {
+          };
