That's heavy stuff.

I was hoping that the first example of using clk notifiers would be
something like mach-davinci replacing it's legacy clock framework
with drivers/clk and then go in and change the horrid cpufreq hack
that is currently in drivers/mmc/host/davinci_mmc.c to use a
clock notifier instead of cpufreq.

Sekhar/Kevin, any chance to have DaVinci converted to Mikes new
clock framework? It doesn't look super-complex and would be a
good example for others I think.

Yours,
