The assignment of the of_node to the aux bridge needs to mark the of_node as reused as well, otherwise resource providers like pinctrl will report a gpio as already requested by a different device when both pinconf and gpios property are present. Fix that by using the device_set_of_node_from_dev() helper instead.

It's quite impolite to force push patches that still under reviewing, this prevent us to know what exactly its solves.
It's quite explicit.
Auxiliary bus emphasis on *compartmentalize*, layer, and distribute domain-specific concerns via *Linux device-driver model*.
Reusing(or sharing) of_node by multiple devices proved that the two subsystems are still tangled together somehow. Which is fundamentally violate the philosophy of compartmentalization.
The way that driver operated is not via Linux device-driver model either, lots of those kind things happens quite implicitly.
But I think beautiful things associated behind this might also be voided, that's it.
This also prevent us from finding a better solution.
Better solution of ? This needed to be fixed and backported to stable, if there's desire to redesign the driver, then it should be discussed in a separate thread.
