Why does this file have to be in include/linux?  I don't think this
exports any structures to userspace, and no other code calls this
driver, so it should all fit into the .c file just fine.

Also, please create the needed Documentation/ABI/ files for these new
sysfs entries, describing how they are used, and what the format of them
are.

Is there any way to detect automatically if this hardware is present in
the system or not?

Otherwise, how will it be loaded by a distro automatically?

thanks,
