4 separate devices, please. And the naming should be consistent with
the rest, so

:rbg:kbd_backlight-zone1

would be closer to something consistent. Should be documented in

Documentation/leds/well-known-leds.txt

. And if you take a look there, you'll notice we already have N900
that has 6 zones with white backlight.

But I'd really like to see plan to go forward. AFAICT there are
keyboards with per-key backlight, and those start to look less like a
set of LEDs and more like a display...

Best regards,
