162306a36Sopenharmony_ciTS-4800 FPGA interrupt controller 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciTS-4800 FPGA has an internal interrupt controller. When one of the 462306a36Sopenharmony_ciinterrupts is triggered, the SoC is notified, usually using a GPIO as 562306a36Sopenharmony_ciparent interrupt source. 662306a36Sopenharmony_ci 762306a36Sopenharmony_ciRequired properties: 862306a36Sopenharmony_ci- compatible: should be "technologic,ts4800-irqc" 962306a36Sopenharmony_ci- interrupt-controller: identifies the node as an interrupt controller 1062306a36Sopenharmony_ci- reg: physical base address of the controller and length of memory mapped 1162306a36Sopenharmony_ci region 1262306a36Sopenharmony_ci- #interrupt-cells: specifies the number of cells needed to encode an interrupt 1362306a36Sopenharmony_ci source, should be 1. 1462306a36Sopenharmony_ci- interrupts: specifies the interrupt line in the interrupt-parent controller 15
