No. We aren't going to do it this way. You just test your current SoC where
all CPUs share clock line. The other SoC that might come later, where
clocks are per cluster, can be handled later.
So, for now you don't need any changes in the driver I believe.
Please let me know if my understanding is wrong somewhere.
