From f203c8c77c7616c099647636f4c67d59a45fe8a2 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Thu, 1 Feb 2024 14:46:01 +0100 Subject: [PATCH 2/2] net: phy: qcom: qca808x: default to LED active High if not set qca808x PHY provide support for the led_polarity_set OP to configure and apply the active-low property but on PHY reset, the Active High bit is not set resulting in the LED driven as active-low. To fix this, check if active-low is not set in DT and enable Active High polarity by default to restore correct funcionality of the LED.
