Looks like Rob still has some feedback that still needs to be addressed.
I'm happy to take these via the RISC-V tree when the bindings are set
(assuming the DTs match whatever gets agreed upons), but also fine if
someone else wants to take it so

Either way, I'm going to drop this (and the v4, which was at the top of
my inbox) as it looks like there'll be at least a v6.
Thanks!
