Currently, we support only rising edge interrupts, and in fact we assume that the interrupt we're given is rising edge (and things won't work if it's not). However, the device supports rising edge, falling edge, level low, and level high interrupts. Empirically, on my system, switching to level interrupts has fixed a problem I had with significant (~40%) interrupt loss with edge interrupts. This issue is likely related to the SoC I'm using (Allwinner H3), but being able to switch the interrupt type is still a very useful workaround. I tested this with each interrupt type and verified correct behavior in a logic analyzer. Add support for these interrupt types while also eliminating the error case of the device tree and driver using different interrupt types.
