|
|
|
- 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>;
