.. code-block:: dts
leds {
compatible = "ibm,opal-v3-led";
phandle = <0x1000006b>;

led-types = "identify", "fault";
phandle = <0x1000006f>;
linux,phandle = <0x1000006f>;
};
/* Other LED nodes like the above one */
};
compatible
property describes LEDs compatibility.
led-mode
property describes service indicator mode (lightpath/guidinglight).
Each node under 'leds' node describes location code of FRU/Enclosure.
The properties under each node:
led-types
