Zephyr SPI sample for reading/writing external ADC

From https://github.com/crfosse/ncs_projects/blob/main/peripheral_zephyr/spi/src/main.c , what is meaning of SPI_3? Since I can't find any *.dts files contain SPI_3?

static void spi_init(void)
{
	const char* const spiName = "SPI_3";
	spi_dev = device_get_binding(spiName);

	if (spi_dev == NULL) {
		printk("Could not get %s device\n", spiName);
		return;
	}
}

Hi,

Unfortunately not, see this case: ADC using SPI in NRF52833

The answer hasn't changed since then, as far as I know.

Best regards,
