In this version I'm introducing a new helper device_find_child_by_name() as proposed by Andy. Andy requested also another helper that could be used for chaining the fwnodes, but I decided not to add that now. I would like to still think about how we should handle exceptions like if there already is a secondary node assigned for a node. The v1 commit message: This series adds support for software fwnode reference handling. In practice it means making fwnode_property_get_reference_args() function usable in the drivers also with software nodes. I send the series originally as RFC [1]. As the first user for the software node references, I'm converting intel_cht_int33fe.c to use them as part of the series.
