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
