+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,sama7g5-chipid
+      - microchip,sama7d65-chipid

+  reg:
+    maxItems: 1
