MCP7940 device tree implementation

Question

Hi I am receiving the error "Linking C executable zephyr\zephyr_pre0.elf FAILED:" which I have found is linked to the mcp7940 device tree node through the error code " undefined reference to `__device_dts_ord_57'" in the device_generated.h file. I want to include in the device tree the interrupt that the mcp7940 on gpio 0 21 of the NRF52805 but I'm not sure if this is best practice or not. How do I solve this error and include the gpio interrupt in the device tree?

Here is the device tree node for the MCP7940n and the corresponding device tree binding.

Device Tree node

&i2c0 {
    status = "okay";
    pinctrl-0 =<&i2c0_default>;
    pinctrl-1 =<&i2c0_sleep>;
    pinctrl-names = "default","sleep";
    clock-frequency = <100000>;
    
    mcp7940n: mcp7940n@6f {
        compatible = "microchip,mcp7940n";
        reg = <0x6f>;
        label = "MCP7940N_RTC";
        //int-gpios = <&gpio0 21 GPIO_ACTIVE_LOW>;  // Use actual GPIO pin where interrupt is connected
    };
};
