I had a quick check in -next and there's an entry for the BMC
driver there.
How about the following? I put you as R, but clearly if you want to be
maintainer then you are *more than* qualified.
Feel free to edit the patch if so, either is fine by me.
You can tack this onto a v21 if you have more changes or I can resend
standalone once the driver is merged.

Thanks,
Conor.
