It is thus crucial to allow the driver for such a controller discriminate between the two. A simple way to do so is to tag the wake-up irqdomain with a "bus token" that indicates the wake-up domain. This slightly abuses the notion of bus, but also radically simplifies the design of such a driver. Between two evils, we choose the least damaging.
