Do you prefer ? I just don't see this as something that should be being varied at runtime; it is supposed to be the maximum speed that the bus can be run at, that's not something that should vary at runtime. Possibly a sysfs thing but honestly if you're prototyping via spidev I'd just set the speed in your application each time it starts.
