I do intend to change the clock lookup on the Samsung series, but we're
currently in the process of trying to do a whole pile of work on not
only adding new SoCs but also cleaning up the existing support and making
a whole pile of code common to all the Samsung SoC family.

I never got the time to go throughly through Francesco's clock framework
but it seemed rathe rcomplicated for our current requirements and also
had a whole pile of style problems that made it really difficult to read.
