They are normally level, active > low. It is wanted. The I2C ioexpander component used for the interrupt supports only edge interrupts. We tested it and it works fine like that. The linux driver is now able to emulate the level interrupt in software, however ... - the DT is shared with other project, it is a HW description and it is not supposed to pair with the specific linux driver - when we tested it, the SW emulation was not really reliable, and we prefer to play on the safe side Francesco
