For all 96Boards, the following standard is used for onboard LEDs.

green:user1  default-trigger: heartbeat
green:user2  default-trigger: mmc0/disk-activity(onboard-storage)
green:user3  default-trigger: mmc1 (SD-card)
green:user4  default-trigger: none, panic-indicator
yellow:wlan  default-trigger: phy0tx
blue:bt      default-trigger: hci0-power

This is just a board configuration and there is absolutely no need to document
this in common LED binding. But if your intention is to document the missing
triggers, then you should look at the patch I submitted long ago.

https://lore.kernel.org/patchwork/patch/1146359/

Maybe I should resubmit it again in YAML format. (thanks for reminding me :P)

Thanks,
Mani

No, I don't think so. The common just means the property linux,default-trigger
is common, but not it values. This can be proved by counter-proving：none of
the triggerrs currently defined in common.yaml is used by 96Boards.

> triggers, then you should look at the patch I submitted long ago.

I'm just trying to eliminate the warnings related to Hisilicon that YAML detected.
So I didn't pay attention to other missing triggers.

Yes, I hope that you will resubmit it. After all, these false positives are
entirely due to YAML's failure to list all triggers. The DTS itself is fine.

By the way, the description of this patch I copied from your patch：
953d9f390365 arm64: dts: rockchip: Add on-board LED support on rk3399-rock960

That's why I Cc to you.

Right, but I was not happy with you mentioning 96Boards in the binding. Because
the triggers are used in more platforms other than 96Boards and they are not
specific to 96Boards. The documentation of triggers itself is fine.

I've now submitted the patch. Please take a look!
