- * This is a driver for the interrupt controller typically found in
- * Xilinx Virtex FPGA designs.
- *
- * The interrupt sense levels are hard coded into the FPGA design with
- * typically a 1:1 relationship between irq lines and devices (no shared
- * irq lines).  Therefore, this driver does not attempt to handle edge
- * and level interrupts differently.
