writing a Device Tree Overlay (.dts) file;
Generating generating a *.dtbo file, output of *.dts file build;
enable enabling the overlay through *.dtbo file.
...
Some devices are used in overlays and those devices are pre-enabled by default in the source, .
Below the reference table for pre-enabled device tree overlay.
Eg: display, touch, cpld, gpio available in overlay.
