So no, it can't be hardcoded in DT. I see. I was thinking how to avoid of going the whole way and creating another controller capability (since this is going to be core code) - could this workaround be enabled just by a boolean DT property at controller's node instead? Or do we expect non-DT platforms to be similarly broken? Best Regards Michał Mirosław
