   4 Subject: [PATCH 1/2] qca807x: add a LED quirk for Xiaomi AX9000
   5
   6 Xiaomi AX9000 has a single LED for each of 4 gigabit ethernet ports that
   7 are connected to QCA8075, and that LED is connected to the 100M LED pin.
   8
   9 So, by default it will only work when in 10 or 100Mbit mode, this is quite
  10 annoying and makes no sense(If they have connected it to the 1000Mbit LED
  11 pin then it would have worked for 10/100 by default as well).
  12
  13 So, to solve this add a check for system compatible as we cant parse if
  14 from DTS in any other way and set the 100M LED to blink on 1000Base-T
  15 as well.
