      • Add R90536 R90537

IO Voltage

RK3568 have three IO voltages, 1.8V/3.3V. For ROCK 3, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V. 

| GPIO       | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0   | 3.3V          | 3.63V     |
| ADC_IN5    | 1.8V          | 1.98V     |

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
