   4 Subject: [PATCH] ARM: dts: turris-omnia: configure LED[0] pin function to
   5  link/activity
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 The marvell PHY driver changes the LED[0] pin function to "On - 1000
  11 Mbps Link, Off - Else".
  12
  13 Turris Omnia expects that the function is "On - Link, Blink - Activity,
  14 Off - No link".
  15
  16 Use the `marvell,reg-init` DT property to change the function.
  17
  18 In the future, once netdev trigger will support HW offloading, we will
  19 be able to have this configured via the combination of PHY driver and
  20 leds-turris-omnia driver.
