+STM32 External Interrupt Controller
+
+Required properties:
+
+- compatible: Should be "st,stm32-exti"
+- reg: Specifies base physical address and size of the registers
+- interrupt-controller: Indentifies the node as an interrupt controller
+- #interrupt-cells: Specifies the number of cells to encode an interrupt
+  specifier, shall be 2
+- interrupts: interrupts references to primary interrupt controller
+
+Example:
+
+exti: interrupt-controller@40013c00 {
+	compatible = "st,stm32-exti";
+	interrupt-controller;
+	#interrupt-cells = <2>;
+	reg = <0x40013C00 0x400>;
+	interrupts = <1>, <2>, <3>, <6>, <7>, <8>, <9>, <10>, <23>, <40>, <41>, <42>, <62>, <76>;
+};
