| 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>; | |
| }; |
