Muic needs a node to be used with extcon_get_edev_by_phandle().
Charger needs a node to reference a regulator.

The pattern is to use the parent device's node.

So is extcon going to be a self-reference then?  

I guess, assuming you even need to look this up via the device tree.

I could use extcon_get_extcon_dev("max8997-muic") and basically hard
code the extcon device name in the charger driver. Then I only need
charger-supply in DTS which could be added to the parent device's node.

Would that be acceptable for everyone?
