Let's keep it in the core child node then where we can still retrieve from the glue parent directly. (I assume you're not suggesting also adding 'wakeup-source' to the qcom glue node, which is where the actual wakeup interrupts live.) The glue and core parts needs to work in concert even if the current implementation tends to make that harder than it should be. Johan
