Thanks for remind.
Actually the "tegra_cpu_car_ops" is more like reset & suspend/resume
handling, it's not really related to clock framework. So it's more like
some functions for CPU power management control. Maybe I can move them
(Tegra20 & Tegra30) to another pm related file later.
How do you think, Stephen?
