The pull-up resistors are inside the SoCs.

Well, I've been taught that devicetree is for describing the hardware,
and
the driver code is for functionality. So that's why I put it in
devicetree.

That's also the reason why I put the list of functions and groups in
devicetree and not in the driver code.

I can change that.
