Check the pin configuration in /sys/kernel/debug/pinctrl/INTC1071:00/pins. But
I believe this is the wrong driver used for not yet released HW.

I suggest you not to communicate in public for this type of issues. We have
internal mailing list for that and other channels to discuss.

I am pretty sure it's irrelevant. IRQ is input mode, the value setters
shouldn't be involved in that at all.
