Hi Maxwell,

If sending a driver out prior to getting access to hardware (nothing wrong
with doing that to get early feebdack!) Then mark it RFC and state
at top of cover letter it's because it is untested on real hardware.

Note there are exceptions to this where we will merge kernel code against
emulation but that is normally about large cross industry standards or similar
not small drivers like this one.

Thanks,

Jonathan
