Hi Preeti,

I thought I was pretty clear when I said you should do that as a follow-up
patch.

This is now doing too many things, it's not a single logical change, and it's
touching code in arch/powerpc and the driver. Which means neither I nor Rafael
can easily merge it.  

So please go back to the v2 you had. And then do the of_property_count_u32_elems()
changes as separate patches.

cheers
