This won't actually do what I think you want. Since the dtsi has the
node name "dp-controller@145B0000", you will end up duplicating a new
node and not build on top of that one.
There's two ways to do it: Always include the unit address, or create
a label in the dtsi such that:
dp_controller: dp-controller@ {....
}
Then in your dts you can, at the root level:
&dp_controller {
... new stuff and overrides ...
};
