Okay, PR below.

I won't put this tag into my linux-next branch until the drivers are in
the clock tree, but it'll let me get my ducks in a row, particularly
beneficial given next week I'll be somewhat AFK! Duck alignment is
currently ongoing in the "jhb100" branch in my repo..

Thanks Brian, Conor.

btw, will you be at LPC or OSSEU?
