Thanks for the pointers. IIUC, that's talking about a different problem:
how to utilize a GPIO key in level-triggered mode. That touches similar
code, but it doesn't really have anything to do with configuring a
different wakeup trigger type.

The two patches would need to be reconciled, if they both are going to
be merged. But otherwise, I think they're perfectly fine to be separate.
