In linux kernel since version 6.4 (release Date: 2023-06-25)  
Say yes here to support the GPIO functionality of a number of
Loongson series of chips. The Loongson GPIO controller supports
up to 60 GPIOS in total, 4 of which are dedicated GPIO pins, and
the remaining 56 are reused with other functions, with edge or
level triggered interrupts.
