Hi Rob, Mark,

Yes, that is fine with me, but can we decide on whether the platform
driver should match "tegra210-agic" or the early driver should bail-out
if clocks/power-domains are present?

I am fine with either, but I think that Rob prefers the tegra210-agic
compat string and Mark prefers to bail-out of the early driver if
clocks/power-domains are present.

Yes exactly, that was the point I was trying to make ;-)
