Thinking deeper: we have two options: a) dt bindings update with the property without knowing how the driver changes will be accepted or not. b) drop the header changes for the macros. I think (a) at this point is risky given the driver usage model is un-clear - the APIs are abstract enough to be used in any way of choice, but we do not want to be stuck with binding that then has to be backward-forward compatible fixup.. So. (b) is better approach, IMHO.. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D
