This is my DTS file for OrangePi Zero2, opened UART5 for attach a GPS module on GPIO.

 

Tried to add 1wire, PPS and SPI , but can't work.

 

maybe help someone.

sun50i-h616-orangepi-zero2.dts

the new one, add bluetooth,  now hciconfig can found hci0, but can't  init it.

And what overlay_prefix do you have set in /boot/armbianEnv.txt?

@mantouboji did you ever get this working?

I'm also trying to get GPS with PPS on Orange Pi Zero 2.

orangepi@orangepi:~$ dmesg | grep pps
[    6.546878] sun50i-h616-pinctrl 300b000.pinctrl: pin PC1 already requested by pps@0; cannot claim for 300b000.pinctrl:65
[    6.546910] pps-gpio pps@0: error -EINVAL: failed to request PPS GPIO
[    6.546918] pps-gpio: probe of pps@0 failed with error -22


My overlay:
 

/dts-v1/;
/plugin/;

/ {
        compatible = "allwinner,sun50i-h616";

        fragment@0 {
                target = <&pio>;
                __overlay__ {
                        pps_pins: pps_pins {
                                pins = "PC1";
                                function = "gpio_in";
                        };
                };
        };

        fragment@1 {
                target-path = "/";
                __overlay__ {
                        pps@0 {
                                compatible = "pps-gpio";
                                pinctrl-names = "default";
                                pinctrl-0 = <&pps_pins>;
                                gpios = <&pio 2 1 0>; /* PC1 */
                                status = "okay";
                        };
                };
        };
};

 

two DTS, one for PPS-GPIO, and one for W1-GPIO,  test successful .

 

Maybe someone  can intergrate into kernel source tree
