This is a follow-up question for the PHY maintainers, if they notice the E- Mail thread: I'm trying to resolve an apparent conflict between DT=20 expectations and a check in the PHY core: device_set_of_node_from_dev(dev, dev->parent); =2E.. devm_of_phy_provider_register(dev, xlate); Passes the letter of the check in __of_phy_provider_register(), but I am no= t=20 sure about the spirit. "dev" here is a MFD child node without a DT node in accordance to DT's=20 writing-bindings instructions ("DON=E2=80=99T create nodes just for the sak= e of=20 instantiating drivers"). The PHY core prohibits a child to register a phy=20 provider to its parent node.
