Just to be clear, cos the last portion of that "yaml shall..." isn't to me, you mean that the driver will support 1 or 11 interrupts but you will make the binding only allow 11? That would be fine. Just note in the commit message that all of these devices have the 11 interrupts. > Is it my understanding right?
