*** 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.

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.63V |
| ADC_IN5 | 1.8V | 1.98V |
</pre>

=== 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

=== Using OpenOCD via GPIO Port ===
Example: if using GPIO1_A0 as swdio pin, GPIO1_A1 as swclk pin and GPIO0_B5 as nrst pin, specify:
adapter driver linuxgpiod
transport select swd

adapter gpio swdio 0 -chip 1
adapter gpio swclk 1 -chip 1
adapter gpio srst 13 -chip 0

(GPIO0_B5: 13 = B*8 + 5)

*** Remove R90526 R90527
*** 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.

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.63V |
| ADC_IN5 | 1.8V | 1.98V |
</pre>

=== 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

=== Using OpenOCD via GPIO Port ===
Example: if using GPIO1_A0 as swdio pin, GPIO1_A1 as swclk pin and GPIO0_B5 as nrst pin, specify:
adapter gpio swdio 0 -chip 1
adapter gpio swclk 1 -chip 1
adapter gpio srst 13 -chip 0

(GPIO0_B5: 13 = B*8 + 5)

* USB 2.0: x1, USB_DP(PIN#27) + USB_DM(PIN#28)
** When we select this USB function, you need to modify the hardware like this.
*** Remove R90526 R90527
*** 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.

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.63V |
| ADC_IN5 | 1.8V | 1.98V |
</pre>

=== 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

=== Using OpenOCD via GPIO Port ===
Example: if using GPIO1_A0 as swdio pin, GPIO1_A1 as swclk pin and GPIO0_B7 as nrst pin, specify:
adapter gpio swdio 0 -chip 1
adapter gpio swclk 1 -chip 1
adapter gpio srst 13 -chip 0
