+description:
+  This interrupt controller is found in Microchip SoCs (SAMA7G5) and provides
+  support for handling up to 2 external interrupt lines.
+
+properties:
+  compatible:
+    enum:
+      - microchip,sama7g5-eic
+
+  reg:
+    maxItems: 1
+
+  interrupt-controller: true
+
+  '#interrupt-cells':
+    const: 2
+    description:
+      The first cell is the input IRQ number (between 0 and 1), the second cell
+      is the trigger type as defined in interrupt.txt present in this directory.
+
+  interrupts:
+    description: |
+      Contains the GIC SPI IRQs mapped to the external interrupt lines. They
+      should be specified sequentially from output 0 to output 1.
+    minItems: 2
+    maxItems: 2
+
+  clocks:
+    maxItems: 1
