From 31b85ba13aa394c98f2d6955b55f3f9a0623c14d Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>

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
