Thanks for explaining that.

Ok, that makes sense. I was trying to get a sense of what belonged in
soc versus the subsystem folders.  My thinking from the limited
reading was the purpose of a SoC folder was to contain the drivers
that were only associated with a system-on-a-chip and not a part you
could buy and place on any board.  A tmp421 sensor is just a generic
part, versus the pwm controller, which is only for the specific SoCs.

That said, there are quite a few misc drivers associated with the
Aspeed parts -- and there are two under review now, so there's a
strong motivation to move those at least into the soc/aspeed folder.
Thanks for these clarifying remarks.
