Device Tree Syntax
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 original SoC string. The reason is that some drivers (the VSP driver for example) look for that SoC string to know what SoC they are running on. If it is missing, it will not load or run correctly.
Here is a correct example of a .dts file for a RZ/G2L board. Notice how "renesas,r9a07g044" is at the end of the line.
/ {
model = "My Really Cool RZ/G2L Board";
compatible = "my-rzg2l-board" , "renesas,r9a07g044";
chosen {
bootargs = "ignore_loglevel rw root=/dev/mmc0blk1";
stdout-path = "serial0:115200n8";
};
};
