Disabling &spi1 via devicetree throws: undefined reference to `__device_dts_ord_111'

Question

Hi guys,

I want to use P1.08 on the nRF52840-DK as a GPIO in my overlay file:

/ {
    gpios {
        compatible = "gpio-keys";
        col1: col1 {
           gpios = <&gpio1 8 GPIO_ACTIVE_HIGH>;
           label = "col1";
        };
    };
    aliases {
        col1 = &col1;
    };
};

Which produces the following warning:

Pin 8 of &gpio1 already assigned to /soc/spi@40004000/pinctrl-1
nrf52840dk_nrf52840.dts(202, 2): Overlapping assignment

This leads me to the following code in nrf52840dk_nrf52840.dts:

&spi1 {
	compatible = "nordic,nrf-spi";
	status = "okay";
	pinctrl-0 = <&spi1_default>;
	pinctrl-1 = <&spi1_sleep>;
	pinctrl-names = "default", "sleep";
};

I've tried to disable &spi in nrf52840dk_nrf52840.overlay as follows:

&spi1 {
    status = "disabled";
};

Which throws the following error:

/home/laci/projects/ncs/toolchains/v2.1.2/opt/zephyr-sdk/arm-zephyr-eabi/bin/
../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: app/libapp.a(main.c.obj):
/home/laci/projects/firmware/nordic-left/src/main.c:42: undefined reference to `__device_dts_ord_111'

How can I disable &spi1 in the overlay file?

Thanks in advance!

Hi Marte, and thanks for your quick reply! 
 Line 42 of my main.c contains the following line: 
 const struct device *spi1_dev = DEVICE_DT_GET(DT_NODELABEL(spi1)); 
 Sorry for the fabulous oversight! I only looked at the devicetree files, and failed to notice this line. I re-enabed &spi1 because I want to use this peripheral. 
 The following code resolves the "pin already assigned" error: 
 arduino_spi: &spi3 {
	status = "disabled";
};
