Hello.
I want use gpioiic on Nanopi NEO with PA0 and PA2 pins.
Nanopi NEO will be master.
Help me, please, to write overlay.
I write:

/dts-v1/;
/plugin/;

/ {
    compatible = "allwinner,sun8i-h3";
};

&{/soc/} {
    gpio: gpio {
        gpio-controller;

        gpioiic0 {
            compatible    = "gpioiic";
            gpios = <&gpio 00 1 0 &gpio 02 1 0>; /* Attach to GPIO pins 00 and 02. Set them initially as inputs. */
            scl = <0>; /*    GPIO pin 00 (PA0) */
            sda = <1>; /*    GPIO pin 02 (PA2) */

        };
    };
};

But it is not worked.
Tell me, please, where I was wrong.
