> Transition the PXA25x and PXA27x CPUs to the clock framework.
> This transition still enables legacy platforms to run without device
> tree as before, ie relying on platform data encoded in board specific
> files.
>
> The transition breaks the previous clocks activation of pin
> control (gpio11 and gpio12). Machine files should be amended to take
> that into account.
>
> This is the last step of clock framework transition for pxa25x and
> pxa27x, leaving only pxa3xx for further work.
