From 8dfd69beccc1c582fba134825df65f7e5d2f17ad Mon Sep 17 00:00:00 2001

Subject: [PATCH 258/454] BCM27XX_DT: Set LED modes from Device Tree
The new default values for LAN7515 (LAN7800) are:
LED0 = 1 (link1000/activity)
LED1 = 6 (link10/link100/activity)
Also add two dtparams - eth_led0 and eth_led1 - to provide user control
over the LEDs.
