I would like to add that OF probing for MFD driver was added the same time as bindings, so that's the time when OF was added. Therefore you cannot use excuse "there is ABI", because your commits added both OF support and non-matching documentation. My stance is: fix the driver, not the binding. Best regards, Krzysztof
