Rockchip RK3566 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:
 +
 
 +
GPIO0_A0 ~ A7
 +
GPIO0_B0 ~ B7

....
 +
GPIO1_D0 ~ D7
 +
 
 +
For Rockchip 4.19 kernel, the GPIO number can be calculated as below, take GPIO4_A7 (PIN26 on 40-PIN HEADER) as an example:
 +
 
 +
GPIO4_A7 = 4*32 + 0*8 + 7 = 135
 +
(A=0, B=1, C=2, D=3)
 +
 
 +
To set GPIO4_A7 output
 +
 
 +
cd /sys/class/gpio
 +
echo 135 > export
 +
cd gpio135
 +
echo out > direction
 +
echo 1 > value    # output high

Rockchip RK3566 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below: 

GPIO0_A0 ~ A7 
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
