Hi,   I managed to make w1-GPIO work in Orange Pi Zero v3 for, for example, the DS18B20 sensor.   However, I have some doubts about setting the GPIO flags for w1-gpio. Many examples provide flags in the form   gpios = <&pio 0 7 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>;   but in the dts file when I use this form it does not work (syntax error) so I have to provide the flags in digital form.   A description of flags and bits is here
