Yeah, I wasn't really trying to place any expectations on how the driver
would look. My motivation in talking about offloads here was to see if
the data direct switch would help at all in trying to ensure the
spi-offloads stuff was being handled generically.

That said, I do think the current implementation binding wise is
probably capable of supporting both directions with little to no
problems, it'd mostly be the kernel's (proposed) interpretation that'd
not be up to it?
