clkdev provides an abstraction which can map these onto the platform, even if you don't use the generic clk API clkdev is still very useful and will help with a lot of these issues.In this specific case I don't know what the ipg or ahb clocks are on iMX (Sascha?), but there is nothing equivalent to them in the FEC cores used on existing ColdFire CPUs. They seem to be platform specific (iMX) more than FEC driver specific.I am sure the Coldfire FEC also needs clocks to work. Just like Mark said, they may be not software controllable. The names 'ipg' and 'ahb' may be i.MX specific though.
Well, yeah, of course there are clocks involved. But you pretty much hit the point here. 'ipg' and 'ahb' here are platform specific.
