How to name a device in the device tree?

I have used a device tree overlay file (dtbo) to add a hardware reference over the i2c-2 node to my device tree. This device is an accelerometer that implements an existing driver that can be found here: https://elixir.bootlin.com/linux/v4.19.94/source/drivers/iio/accel/mma8452.c My device appears as iio:device0 in the /dev directory:

My device can also be viewed in:

debian@beaglebone:/sys/class/i2c-dev/i2c-2/subsystem/i2c-2/device/2-001c$ ls
driver       modalias  of_node  subsystem  uevent
iio:device0  name      power    trigger0

Here you can see the specifics of the device naming:

debian@beaglebone:/sys/class/i2c-dev/i2c-2/subsystem/i2c-2/device/2-001c/iio:device0$ cat uevent
MAJOR=248
MINOR=0
DEVNAME=iio:device0
DEVTYPE=iio_device
OF_NAME=accelerometer
OF_FULLNAME=/ocp/i2c@4819c000/accelerometer@1C
OF_COMPATIBLE_0=fsl,mma8451
OF_COMPATIBLE_N=1

**My question is, where does this device get its name as iio:device0?** I assume this is simply a default name as I haven't specified one. **My question therefore becomes: How do I specify a name for my device in the device tree? It seems I would like to change the DEVNAME somehow.** I do not see any reason for this name in my dtbo file, which can be seen below:
