Hi Hui Liu,

+		color = <LED_COLOR_ID_RED>;
+		label = "red";

Please remove the deprecated "label" property. Since you already have
"color" set you only need to add "function". On phones for the
notification LED we usually use "function = LED_FUNCTION_STATUS;"

Also depends on what your hardware looks like, if it's 3 separate LEDs
then with label replaced it would be okay.
If the 3 LEDs are in one spot (so you can mix the colors with it), then
please make it a RGB multi-led like e.g. in sm8550-qrd.dts.


I already asked for this and it was ignored:

https://lore.kernel.org/all/6aa67adb-a4d5-40da-a261-c90050ac04b2@xxxxxxxxxx/

Let's engage three different community reviewers to repeat the same, one
feedback. This is just disrespectful to our time.
Sorry, I ignored that comments, I will submit v4 to update it. Thanks for your comments.

Best regards,
Krzysztof
