Code:
                       my_pps_pin@0 {
                               linux,phandle = <0xba>;
                               phandle = <0xba>;
                               allwinner,pins = "PC8";
                               allwinner,function = "gpio_in";
                               allwinner,pname = "pps_gpio";
                               allwinner,muxsel = <0x0>;
                               allwinner,pull = <0x1>;
                               allwinner,drive = <0x0>;
                               allwinner,data = <0xffffffff>;
                       };

Then, you declare the device (again after vdevice@0) :

Code:
               ppsgpio_device@0 {
                       compatible = "pps-gpio";
                       gpio = <0x30 0x2 0x8 0x0>;
                       pinctrl-names = "default";
                       pinctrl-0 = <0xba>;
                       status = "okay";
               };

Then, recompile the dtb (always keep a backup of the original)

thx. Smile  i'll give it a try after the wedding... maybe tomorrow.

Congratulation on the wedding.
