This Firmware target is applied to Magolor/Maglia/Magma/Maglet etc. Is pen stuffed on all boards. I believe not. If so, can you please apply this configuration only on the boards where pen is stuffed and mark this GPIO as PAD_NC on other boards.

Otherwise you might end up receiving spurious wakes due to this GPIO configuration.
