I am not using the nrf5340DK development board; instead, I am using the nrf5340 chip, and the SDK version I'm using is V3.1.0. I defined the I2C child node "lt3582" in the device tree, and this child node is also visible under the "i2c1" node. However, the function I2C_DT_SPEC_GET in the main function keeps indicating that this child node is not defined. Could anyone please help me with this?
In the tutorial, it's possible to add one's own device tree files, but in my current device tree setup, there doesn't seem to be a place to add device tree files. Currently, there are two device tree files: nrf5340dk_nrf5340_cpuapp_ns.dts and app.overlay. The app.overlay file is the one I modified to configure device tree pins, and I'm not sure if app.overlay is my custom device tree file.

It’s possible to create a custom i2c child node, like the “mysensor” node in the DevAcademy course, and not create a proper binding to a Zephyr driver, but instead use the i2c driver directly from your application. Do you see any actual errors/warnings reported in the build output here:
If so, could you please post the log here?
