Paul/Conor: what is the right tree for a arch/riscv/configs/defconfig
patch like this?

Thanks,
Drew

I dunno, in arm land the various platform maintainers take care of this
kind of thing for their own platforms. That hasn't happened (yet?) for
riscv. I've probably taken most SoC support things like this recently.

Does it need to be built-in, or would a module work?

It's not a huge driver (~20KB), but it all adds up.

cheers
