It is quite common for users to delete power supply nodes of regulators which aren't yet supported. The idea of a function call or devicetree property which allows use of dummy regulator is not new. This implementation uses barebox specific devicetree property "barebox,allow-dummy-supply" to allow switching to dummy power regulator. Basically just catch the regulators ensure_probed error, if this property is set.
