That being said, this is an additional feature we can add after this
driver is moved.

I would like this series to concentrate on the cleanups necessary to
move to drivers/*, then additional features to support other SoCs can be
added on top.

Keerthy, please prepare a patch to generalize this to other SoCs by
using dev_attr for this SoC specific data.   We can add it after this
series is merged upstream.

Thanks,

Kevin
