GPIO number

Rockchip RK3568 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below: 

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

For Rockchip 4.19 kernel, the GPIO number can be calculated as below, take GPIO3_C2 (PIN2 on 10-PIN HEADER) as an example: 

GPIO3_C2 = 3*32 + 2*8 + 2 = 114 
(A=0, B=1, C=2, D=3)

To set GPIO3_C2 output 

cd /sys/class/gpio
echo 114> export
cd gpio114
echo out > direction
echo 1 > value     # output high
echo 0 > value     # output low
