The binding prefers naming the led nodes differently:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/leds/leds-gpio.yaml?h=v6.12#n22
If you must name the nodes this way, can you document why in a comment
in the devicetree?

Does this expander really only expose the identify led?

Bit of nitpick, but perhaps the node label could be improved?
fan_leds0? And fan_leds1 below?
