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

device-name:green:user1  default-trigger: heartbeat
device-name:green:user2  default-trigger: mmc0/disk-activity
                                          (onboard-storage)
device-name:green:user3  default-trigger: mmc1 (SD-card)
device-name:green:user4  default-trigger: none, panic-indicator
Actually, having one LED as heartbeat and second as panic indicator
only... Could those be merged and remaining LED used to something
useful?
No. Our intention is to leave one LED as a panic indicator and a dedicated
LED for heartbeat. If user wants to override the defaults, he can always do
with any LEDs.

The purpose of this series should be standardize Led labels that's why I
would expect that leds will be called in the same way on all these
boards that's why I am not getting why there is board name.

green:user1 or just user1 should be enough.
green:user1 is better. Also... I guess this should go to the LEDs
list... and if you want to make names standard, maybe there's better
naming than user1..user4?
These are user LEDs and that's why the `userN` naming convention comes into
place. Here I agree to move with "green:user1" format and sending it to the
LEDs list.

Thanks,
Mani
