Hm, this is actually a bit more tricky. I missed that the direction of the
SAIF is runtime programmable and not fixed. And while your probably won't
switch between transmit and receive dynamically, whether a SAIF is used as
transmitter or receiver is board specific. So I guess we need to add a
devicetree property to describe this.
