+description:
+  This binding describes the Atmel/Microchip Chip ID register block used
+  for SoC identification and revision information. It requires compatible
+  strings matching specific SoC families and a reg property defining the
+  register address and size.
+
+properties:
+  compatible:
+    enum:
+      - atmel,sama5d2-chipid
+      - microchip,sama7d65-chipid
+      - microchip,sama7g5-chipid
+
+  reg:
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+
+unevaluatedProperties: false
+
+examples:
+  - |
+    chipid@fc069000 {
+        compatible = "atmel,sama5d2-chipid";
+        reg = <0xfc069000 0x8>;
