Kernel-4.18.0-80.el8_st,stm32-exti

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>;
};
