Orange Pi One board has a SY8113B regulator, which is controlled via GPIO and capable of outputing 1.1V when the PL6 GPIO is set to output 0 or 1.3V when the PL6 GPIO is set to input or output 1, and the output is the power supply of the ARM cores in H3 SoC. Add the device tree node of this regulator and set the cpu's cpu-supply property to it.
