Device context's field data->soc is currently obtained by comparing
of_compatible's. Provide soc_type as .data field in device's match
table, as it is done in most drivers.

Zhang & Eduardo are Thermal Maintainers (+ I'm Maintainer for
Samsung Thermal) so I assume you meant "Reviewed-by:"?

I meant Acked-by :) I don't have to be a subsystem maintainer to ack a
patch. The reviewed-by has a stronger statement than the acked-by.

The patch looks good to me.
