Subject: [PATCH 069/114] Fix the activity LED in DT mode
|
|
|
|
Add a "leds" node to the base DTBs, and a subnode for the activity
|
|
LED. You can change the LED function like this:
|
|
|
|
dtparam=act_led_trigger=heartbeat
|
|
|
|
Add aliases for the other main nodes (soc, intc).
|
|
|
|
Issue: linux #757
