It's a bit unclear here. Is this a general recommendation or is it
specific to _this_ location in the code?

> Just make an external function for the register

Dou you suggest to share something like a1_register_clk()? Currently, it
is not good idea, axg-audio uses slightly different way to register
their clocks.
