1*c66ec88fSEmmanuel VadotTS-4800 FPGA interrupt controller 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotTS-4800 FPGA has an internal interrupt controller. When one of the 4*c66ec88fSEmmanuel Vadotinterrupts is triggered, the SoC is notified, usually using a GPIO as 5*c66ec88fSEmmanuel Vadotparent interrupt source. 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotRequired properties: 8*c66ec88fSEmmanuel Vadot- compatible: should be "technologic,ts4800-irqc" 9*c66ec88fSEmmanuel Vadot- interrupt-controller: identifies the node as an interrupt controller 10*c66ec88fSEmmanuel Vadot- reg: physical base address of the controller and length of memory mapped 11*c66ec88fSEmmanuel Vadot region 12*c66ec88fSEmmanuel Vadot- #interrupt-cells: specifies the number of cells needed to encode an interrupt 13*c66ec88fSEmmanuel Vadot source, should be 1. 14*c66ec88fSEmmanuel Vadot- interrupts: specifies the interrupt line in the interrupt-parent controller 15
