Hi Joachim,

I'm not sure why you need this. I guess it is related to my question in
patch #2 about using clock-indices? Can you explain why this function is
required?

Anyways if returning the clock index is something that is really needed
then why not rename it to "of_clk_get_index" and put it in
drivers/clk/clk.c?

Thanks,
Mike
