No guarantee that they'll not change, especially in a situation where we
have two devices on different speeds on a bus working at the same time.

Are you saying, that between a prepare and unprepare there could be transfers 
for another device? Then all the clock setting couldn't be done in prepare 
either.
Apart from that, if two transfers in the same message are not guarantied to 
have the same speed, this still needs to be fixed. I'll roll a v2.

There are two prepares, I don't know which you're talking about.  The
most common is prepare_transfer_hardware() which is used to power up the
hardware and may have many transfers for many devices before it is
reversed.  The other is prepare_message() which is called once per
message.
