Today we will take a look how to add a device to the device tree. As an example, I will add a LED to the device tree. We also have to modify the pin multiplexing to accomplish our task.

Surprising to know that there is another thing we can include in the inclusion #include directive. Before this, what I knew was that only header (*.h) file we may include there. But now, you revealed that there is another thing we may include there. How it works and what else we may include in that directive?

Great! But how to use this dts overlay in Linux Kernel Driver? I mean, how to attach dts to kernel?

Hi, I am new embedded linux. If I want to change Device tree file by write a new file name. Do I need to config the u-boot to point to new device tree file?
