A bit more description of exactly _what_ these devices do would be
helpful.

Also, how does userspace interact with the driver?  What api(s) are you
using/creating?  What userspace tools work with the device?

In short, we need more than just a one sentance description to be able
to properly review the code and provide text for a user to know what to
do with this driver.

Can you fix all that up and send a v2?

thanks,
