Personally, I'm not so fond of the <foo>-%u node names, and prefer
<foo>-<function>.  With the former, it's way too easy to have a silent
override in your .dts(i) stack.
Cfr. commit 45f5d5a9e34d3fe4 ("arm64: dts: renesas: r8a77995: draak:
Fix backlight regulator name")

How about using `lan-led`, `sys-led` and `wan-led` here?

Documentation/devicetree/bindings/leds/leds-gpio.yaml says "led-%u"
is the preferred form, but that anything containing "led" as a substring
is accepted.  So I'd go for "led-lan" etc.

BTW, you can validate your DTB against the leds-gpio DT bindings
by running:

    make dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/leds/leds-gpio.yaml

when I'm talking to journalists I just say "programmer" or something like that.
