Subject: [PATCH 0/2] nvmem: Fix reading MAC address from OCOTP on i.MX
Date: Fri, 11 Jul 2025 13:55:46 +0200 [thread overview]
Message-ID: <20250711120110.12885-1-ceggers@arri.de> (raw)
There is a (minor?) regression (also propagated via -stable series)
which causes wrong Ethernet MAC addresses read from internal OTP.
Probably this doesn't affect many system as usually the MAC address is
already read from OTP (called OCOTP on i.MX) by the boot loader and
then passed verbatim to the kernel via device tree fixups. Only if the
MAC isn't present in the device tree, the kernel reads it from the OTP
itself.
