If you're sticking to global names for now, you could just skip converting this clock altogether. I suspect .parent_names will be around for some time.
On the other hand, if you really want to get rid of global clock name based parenting, you could use clk_hw pointers, and have the probe function fix up this one based on the compatible string. That's what I did.
Just my two cents.
