Top Level (root node)

Compatible for the SoC

• The .dtsi file for each SoC will have a "compatible" string to specify that SoC it is. If you decide to make your own top level compatible, make sure you include the origonal string. The reason is that some drivers look for that string to know what SoC they are running on. If it is missing, it will not load.

Here is a correct example of a .dts file:

/ {
	compatible = "my-rzg2l-board" , "renesas,r9a07g044";
	#address-cells = <2>;
	#size-cells = <2>;
};
