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
