| 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) |
| |
| Optional properties: |
| |
| - hwlocks: reference to a phandle of a hardware spinlock provider node. |
| |
| 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>; |
| }; |
