Ok, I see. Let's go with Brian's suggestion then.

For reference, I'd also be fine with the alternatives
we mentioned. We've done all of those before:

1. Include the actual clk driver in the immutable
   branch to cover both compile-time and (potential)
   runtime dependencies.

2. Merge the initial clk driver through the soc tree
   alone with an Ack from Brian.

3. Decouple the dts from the binding, using only
   numeric clk IDs for the initial merge in 7.5,
   start using the binding in 7.6.

4. Merge the clk driver in 7.5 through the clk tree,
   merge the rest in 7.6 through the soc tree.
