    The same way as now, of course. Only getting the clock frequency would be 
different, via clk_get_rate()...

    No, this item has never been covered by the clk layer IIRC. That's what 
the device node props are for.

    I'm not sure why you call it "fake". It's a normal clk implementation, 
just not converted to the common clk framework.
