Hi,

From the overlapping register addresses in the examples and this
description, it looks like the pinctrlr and gpio controller are 1 
block.
If so, then there should only be 1 node.

Well, that's what I had until Linus W. just told me to do the opposite:

Just pull all these down two levels and make them one device
each instead of having them inside the pin controller node
like this.
