While applying this series mvebu/dt, I got few warning with "ARM: dts:
mvebu: 98dx3236: Rename nand controller node".

I fix them and also use the new partition binding, the diff is the
following:

I amended your patch with it, but if you don't agree with it, I can
still modify it, the branch is not immutable yet.
