Specifies the number of cells needed to encode 9*c66ec88fSEmmanuel Vadot an interrupt source. Supported trigger types are low-to-high edge 10*c66ec88fSEmmanuel Vadot triggered and active high level-sensitive. 11*c66ec88fSEmmanuel Vadot- interrupts: describes which input line in the interrupt parent, this 12*c66ec88fSEmmanuel Vadot fic's output is connected to. This field property depends on the parent's 13*c66ec88fSEmmanuel Vadot binding 14*c66ec88fSEmmanuel Vadot 15*c66ec88fSEmmanuel VadotPlease refer to interrupts.txt in this directory for details of the common 16*c66ec88fSEmmanuel VadotInterrupt Controllers bindings used by client devices. 17*c66ec88fSEmmanuel Vadot 18*c66ec88fSEmmanuel VadotExample: 19*c66ec88fSEmmanuel Vadot 20*c66ec88fSEmmanuel Vadotamazon_fic: interrupt-controller@fd8a8500 { 21*c66ec88fSEmmanuel Vadot compatible = "amazon,al-fic"; 22*c66ec88fSEmmanuel Vadot interrupt-controller; 23*c66ec88fSEmmanuel Vadot #interrupt-cells = <2>; 24*c66ec88fSEmmanuel Vadot reg = <0x0 0xfd8a8500 0x0 0x1000>; 25*c66ec88fSEmmanuel Vadot interrupt-parent = <&gic>; 26*c66ec88fSEmmanuel Vadot interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>; 27*c66ec88fSEmmanuel Vadot}; 28
