DT is a method for the bootloader to pass information about the hardware
to the kernel.  Udev performs userspace actions based on kernel-provided
information about hardware (and other things).  The two are (almost)
entirely unrelated since the kernel reports the same events to udev
regardless of the form in which it received the information.
