I'm currently attempting to change the way clks are registered so
that we don't return clk pointers from clk_register and have
users add OF clk providers that return clk_hw pointers instead of
clk pointers. Just a note, that this whole thing should be
deleted in the next cycle if I can convert everything!

EXPORT_SYMBOL_GPL?

Do I need to pick this up?
