* How to set up clock using clock driver functions:
|
|
*
|
|
* 1. Setup clock sources.
|
|
*
|
|
* 2. Setup voltage for the fastest of the clock outputs
|
|
*
|
|
* 3. Set up wait states of the flash.
|
|
*
|
|
* 4. Set up all dividers.
|
|
*
|
|
* 5. Set up all selectors to provide selected clocks.
