labels missing from DTS in nRF Connect SDK 2.1.0

[denis]

In nRF Connect SDK 2.1.0 the devices in the DTS file are missing the "label".

For example, in nRF Connect SDK 2.0.0:

gpio0: gpio@842500 {

        compatible = "nordic,nrf-gpio";

        gpio-controller;

        reg = <0x842500 0x300>;

        #gpio-cells = <2>;

        label = "GPIO_0";

        status = "disabled";

        port = <0>;

};

But in nRF Connect SDK 2.1.0:

gpio0: gpio@842500 {

        compatible = "nordic,nrf-gpio";

        gpio-controller;

        reg = <0x842500 0x300>;

        #gpio-cells = <2>;

        status = "disabled";

        port = <0>;

};

This breaks code that does dynamic lookup of the device using the function device_get_binding (in my case passing in a string that is constructed at run time).

The developers recommend not using device_get_binding()

However, it is strange that the Zephyr examples use strings with device_get_binding.

For example:

samples\boards\nrf\nrf53_sync_rtc\net\src\main.c
67: ipm_dev = device_get_binding("IPM_2");

samples\drivers\flash_shell\src\main.c
const char *name;
name = argv[1];
714: dev = device_get_binding(name);

samples\drivers\i2s\litex\src\main.c
37: host_i2s_rx_dev = device_get_binding("i2s_rx");

samples\sensor\thermometer\src\main.c
17: temp_dev = device_get_binding("TEMP_0");

samples\subsys\usb\hid\src\main.c
154: hdev = device_get_binding("HID_0");

samples\subsys\usb\hid-cdc\src\main.c
550: hid0_dev = device_get_binding("HID_0");
556: hid1_dev = device_get_binding("HID_1");

samples\subsys\usb\hid-mouse\src\main.c
249: hid_dev = device_get_binding("HID_0");
