TS-4800 FPGA interrupt controller TS-4800 FPGA has an internal interrupt controller. When one of the interrupts is triggered, the SoC is notified, usually using a GPIO as parent interrupt source. Required properties: - compatible: should be "technologic,ts4800-irqc" - interrupt-controller: identifies the node as an interrupt controller - reg: physical base address of the controller and length of memory mapped region - #interrupt-cells: specifies the number of cells needed to encode an interrupt source, should be 1. - interrupt-parent: phandle to the parent interrupt controller this one is cascaded from - interrupts: specifies the interrupt line in the interrupt-parent controller
