How to specify uart on modem drivers

[mjm987]

At least for the the simcom,sim7080 LPWA modem driver using uart0 seems to be hardcoded.

Following compiles without error if defined in the DTS overlay:

&uart0 {
	compatible = "nordic,nrf-uart";
	status = "okay";
        current-speed = < 115200 >;
	test_simcom_sim7080: sim7080 {
		compatible = "simcom,sim7080";
		label = "simcom,sim7080";
		mdm-power-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
	};
};

But if I try to reference uart1, following error appears:

zephyr/drivers/modem/libdrivers__modem.a(simcom-sim7080.c.obj): in function `modem_init':
.../zephyr/drivers/modem/simcom-sim7080.c:2410: undefined reference to `__device_dts_ord_128'

I couldn't find any CONFIG Options to specify the uart.

Any suggestions?

Solution: on uart1 you have to specify compatible = "nordic,nrf-uarte" and not compatible = "nordic,nrf-uart"
