GPIO number

Rockchip RK3588 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32 pins, naming as below: 

GPIO0_A0 ~ A7 
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7
   
GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

GPIO2_A0 ~ A7
....
GPIO2_D0 ~ D7

GPIO3_A0 ~ A7
....
GPIO3_D0 ~ D7

GPIO4_A0 ~ A7
....
GPIO4_D0 ~ D7


For Rockchip 5.10 kernel, the GPIO number can be calculated as below, take GPIO4_D5 as an example: 

GPIO4_D5 = 32*4 + 8*3 + 5 = 157
(A=0, B=1, C=2, D=3)

Gpio number.png

To set GPIO4_D5 output 

# cd /sys/class/gpio
# echo 157 > export
# cd gpio157
# echo out > direction
# echo 1 > value     # output high
# echo 0 > value     # output low
