    Do we need to tie unused interface inputs on the CYW43907?


      There are a few interfaces we're not using in our design.  Is there a list of what to do with unused inputs or I/O lines on SDIO, MII, S/PDIF, or USB interfaces?  Are they internally pulled to safe / idle states, or do they need to be manually strapped?  If they need to be tied, are resistors required or can we connect directly to VIO/GND?  I realize this may depend on the signal / interface signal, but a list of what to do with unused signals would be very helpful.
