The last email asked you to adopt A1 method, but you did not reply?

I understand that this should be a controller, just two address 
descriptions. One is the various PLL registers and one is the clock for 
the peripherals. And PLL is to provide a clock source for various 
peripheral clocks. So a clock controller is reasonable. I think you got 
it wrong.

Ok, if you insist on using two clock controllers,, please provide your 
the reason and example code?
