Can a type be declared as a oneOf or something like that? I wasn't able to get this to work with a node name of just 'nvmem'. If anybody has any suggestions, I'll gladly try them. I've renamed the node from pmic-nvmem to nvmem-0 in v2, though. https://lore.kernel.org/all/20250226-max77759-mfd-v2-3-a65ebe2bc0a9@xxxxxxxxxx/ Cheers, Andre
