"renesas,tx-fifo-size" and "renesas,rx-fifo-size" are part of the existing
bindings, so I'm a bit reluctant to change these.
Hmm, since the original bindings didn't specify the default values,
I could make them chip-specific, though.

The only other property is "num-cs", which can have any value if you
start using the generic "cs-gpios".

when I'm talking to journalists I just say "programmer" or something like that.
