That makes sense to me, thanks for the advice.

The only note is that 5 (the clk patch) is depended on by 6/7 to
compile (they use the header value in 5)... So I'll keep those together!

So all in all it will be the dt-binding changes + stmmac changes in one
series for networking, and the clock + devicetree changes via
ARM/Qualcomm if I am following properly.

I'll go that route for v3 and link here (just to make finding the split
easier) unless someone objects (got some time as I need to refactor
based on series feedback)!

Thanks,
Andrew
