Subject: [PATCH 1/5] ARM: dts: imx6ull-tarragon-common: Fix Ethernet regression
Date: Sun,  4 Oct 2026 16:01:19 +0200	[thread overview]
Message-ID: <20261004140123.46461-2-wahrenst@gmx.net> (raw)
In-Reply-To: <20261004140123.46461-1-wahrenst@gmx.net>

The commit e2ba87c745ca ("ARM: dts: imx6ul: Set macaddress location in ocotp")
introduced a OTP to MAC address mapping on DT level. But the Tarragon
platform relies on a different MAC address mapping, which is provided by
U-Boot. So unfortunately the mentioned commit breaks Ethernet on the
Tarragon platform. Fix this by dropping the additional MAC address mapping.

Fixes: e2ba87c745ca ("ARM: dts: imx6ul: Set macaddress location in ocotp")
