No, this lot is directed towards devices that use serial buses such as
i2c  and SPI whereas
UIO is, from my admittedly cursory knowledge, intended for devices which
can have
their control registers memory mapped into user space.

Looks like I need to be a bit more specific in my descriptions. It's
terrible but as all the
sensors etc I work with are connected like this it never occurred to me
to make it
explicit in the description.
