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

So lets adopt the same for Ultra96, which is one of the 96Boards
CE and AI platform. Since the WLAN and BT LEDs are hardwired onboard,
consolidate only User LEDs.
Hello,

Any update on this patch?
I am still waiting for reaction from Rob.
We are keep trying to keep backward compatibility and this patch is
breaking it that's why I want to know DT guys reaction on this change.
dts changes and backwards compatibility are ultimately up to the
platform maintainers. Your users can yell at you if they care. I only
ask that changes that break compatibility are documented as doing so.

Personally, I'm in favor of this change. I'd rather seem uniformity
across boards and this is just a dev board and LED functions won't
affect booting.
Ok.

Then please fix the patch and do it in a way

label = "green:user1"; /* ds2 */

ds2 reflects name on schematics.

in ds4 case default trigger is changes to mmc1. It suggests sd/emmc but
on ultra96 it is sd slot and wifi on second slot.

ds5 - linux,default-trigger = "none"; looks weird. None trigger should
be simply ensured by removing that line.

Thanks,
Michal
