12description:
13  iomux0 is responsible for routing some functions to either the FPGA fabric,
14  or to MSSIOs. It only performs muxing, and has no IO configuration role, as
15  fabric IOs are configured separately and just routing a function to MSSIOs is
16  not sufficient for it to actually get mapped to an MSSIO, just makes it
17  possible.
