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 GPIO4_D1 (PIN26 on 4-0PIN HEADER) as an example:
GPIO4_D1 = 4*32 + 3*8 + 1 = 153 (A=0, B=1, C=2, D=3)
To set GPIO4_D1 output
cd /sys/class/gpio echo 153 > export cd gpio153 echo out > direction echo 1 > value # output high echo 0 > value # output low
