As previously discussed, 'compatible = "clock";' isn't a very good binding; but I won't say any more on this here since Shawn reworks this code in his series.

Since aips isn't addressable, and there is no 'reg' property in this node, the name can simply be 'aips' or 'aips1' (or whatever name is used in the imx reference manual). Same goes for the spba node below.

Unfortunately we're leaking Linux implementation details here by needing to use the name "fec_clk". This will require some more thought on the best way to handle (but I'm not asking you to change anything yet).
