I strongly feel we must reuse cpufreq-cpu0 driver here after adding a clk/regulator driver for tegra to support all that.
@Stephen: If you want we can keep all that tegra specific stuff (clk/regulator) in tegra-cpufreq.c, but we can easily use cpufreq-cpu0 driver without much complications..
I have tried it earlier, got some comments and then got busy in other stuff.. https://lkml.org/lkml/2013/8/7/364

Btw, why do you need this here?
