Without this, we would need a new type of match table that would probably duplicates part of the of_match_table to be able to match software_node against a driver. I did not found an other way to do it without modifying drivers individually to support software_nodes. -- Clément Léger, Embedded Linux and Kernel engineer at Bootlin https://bootlin.com
