Subject: [PATCH 0/2] arm64: dts: rockchip: fix Ethernet PHY on Theobroma PX30 devices
Date: Mon, 02 Feb 2026 11:27:24 +0100 [thread overview]
Message-ID: <20260202-px30-eth-phy-v1-0-ef365be64922@cherry.de> (raw)
This removes the reliance on the bootloader setting up the Ethernet PHY
for the Linux kernel to be able to use Ethernet.
This is due to the HW default of the PHY reset line being active and the
MDIO auto-detection mechanism not controlling a PHY's reset line such
that we need to hardcode the PHY ID in the compatible property for it to
be usable by the kernel, regardless of what the bootloader is doing.
We only ever had one PHY (DP83825) for both devices, so it's fine to
hardcode this way.
