Hi Boris,

It is a bit strange to see only a .prepare and .disable callback
populated. What happens if a driver calls clk_disable and then
clk_enable? You clock will still be disabled in hardware.

Oops, I haven't thought about that.
I did this because the clk_pll_disable does not sleep, but this is a big mistake :-(.

I'll fix this.

Thanks.

Best Regards,

Boris
