   4 Subject: [PATCH 2/2] net: phy: qcom: qca808x: default to LED active High if
   5  not set
   6
   7 qca808x PHY provide support for the led_polarity_set OP to configure
   8 and apply the active-low property but on PHY reset, the Active High bit
   9 is not set resulting in the LED driven as active-low.
  10
  11 To fix this, check if active-low is not set in DT and enable Active High
  12 polarity by default to restore correct funcionality of the LED.

  14 Fixes: 7196062b64ee ("net: phy: at803x: add LED support for qca808x")
