The flags should be documented - what do these flags mean?  The
DMAEngine stuff is a bit fun but I don't think there's yet been any

This isn't true, the driver can be used with any machine driver.  It's
true that many machines using the FSI driver can be supported with the
simple-card driver but others are also fine.

Is this definitely something that would be fixed by hardware design?

Why wouldn't stream mode be desired?
