[RFC,PATCH 1/7] arm: add a common struct clk

Hi Hartley,

This may have been a little cryptic, I'm sorry. The reason for not adding a 
'rate' member to the public clock API is that there would be now two methods 
for getting the rate of a clock: calling clk->get_rate or accessing clk->rate 
directly. The latter is not always guaranteed to work (perhaps there's a clock 
out there that needs an explicit HW query to get the rate), so we don't want 
generic drivers to be able to access this.

Cheers,


Jeremy
