(I think YAML allowed it at one time, but it is deprecated) The only way to fix it in the tool would be to define some way to handle the collision like renaming properties and then undoing that. > Do you plan to enforce it at some point? How close are you? Soon as this patch is merged. There's a switch in parsing tools to disallow the collision, so it will be an error instead of a warning. > > Cc: Nicolas Ferre <nicolas.ferre@xxxxxxxxxxxxx> > > Cc: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx> > > Cc: Ludovic Desroches <ludovic.desroches@xxxxxxxxxxxxx> > > Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx > > Signed-off-by: Rob Herring <robh@xxxxxxxxxx> > > Acked-by: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx> Is someone going to apply this?
