GPIO number

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
GPIO0_D0 ~ D7
   
GPIO1_A0 ~ A7
....
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
echo 0 > value # output low
