7 title: Xilinx AXI GPIO controller
10   - Neeli Srinivas <srinivas.neeli@amd.com>
13   The AXI GPIO design provides a general purpose input/output interface
14   to an AXI4-Lite interface. The AXI GPIO can be configured as either
15   a single or a dual-channel device. The width of each channel is
17   generate an interrupt when a transition on any of their inputs occurs.
