- STM32 External Interrupt Controller
- Required properties:
- - compatible: Should be:
- "st,stm32-exti"
- "st,stm32h7-exti"
- "st,stm32mp1-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
- (only needed for exti controller with multiple exti under
- same parent interrupt: st,stm32-exti and st,stm32h7-exti)
- 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>;
- };
