  From: Jacky Huang <ychuang3@nuvoton.com>

Moved the declaration of extern functions ma35d1_reg_clk_pll() and
ma35d1_reg_adc_clkdiv() from the .c files to the newly created header
file clk-ma35d1.h.

This part of the patch does not relate to the decription, it
looks like a minor cleanup that should be a separate patch.

The actual change looks good and required, but I can't apply it
if it's mixed with unrelated changes like this.

Dear Arnd,


Thanks for the advice.

I will extract the unrelated parts from this patch and create another 
patch for them.


Best Regards,

Ok, sounds good. It would be great to still get this today or tomorrow
though, as the merge window probably opens on Monday and I want to
have the tree in a good state before I send my pull request to Linus.
