   4 Subject: [PATCH 258/454] BCM27XX_DT: Set LED modes from Device Tree
   5
   6 The new default values for LAN7515 (LAN7800) are:
   7
   8   LED0 = 1 (link1000/activity)
   9   LED1 = 6 (link10/link100/activity)
  10
  11 Also add two dtparams - eth_led0 and eth_led1 - to provide user control
  12 over the LEDs.
