Chunfeng, GPIO16 can be used as EINT16 mode, but the pinmux should be 0.
If you want to set its default mode to iddig, you should set it in dts.
I set it in DTS, but it didn't work, because when usb driver requested
IRQ, pinmux was switched back to default mode set by
MTK_EINT_FUNCTION().
After confirmed, there are something wrong with data sheet and pinmux
table, and GPIO16 can only receive interrupt by mode 1. So

Linus,
We find there are some other pins still have the same problem, so please
hold on it. Sorry for so much noise.
Did you made any progress on this? I didn't see any patch on the mailing
list.
Regards,
Matthias
