I would like to set a GPIO to output-high during the boot. In this case, the GPIO is PG0 whose number is 192. The device tree overlay is /dts-v1/; /plugin/; / { compatible = "allwinner,sun50i-a64"; fragment@0 { target = <&pio>; __overlay__ { gpio_out_override_hog { gpio-hog; gpios = <192 0>; /* PG0 */ output-high; line-name = "PG0-gpio-hog"; }; }; }; }; However, after the application and reboot, I do not see any init information in "/sys/kernel/gpio" about GPIO 192. There is no "/sys/class/gpio/gpio192" folder existed after boot either. Is there anything wrong in the overlay file?
