Subject: [PATCH 1/2] nvmem: imx-ocotp: reverse MAC on imx6qdl
Message-Id: <20221128074901.8D80B135A@mail.steuer-voss.de>
Precedence: bulk

Ethernet MAC on iMX6Q/DL is stored in OTP in little-endian byte order. I
suspect that this is true for all iMX flavors. If so, we could get rid
of the .reverse_mac_address attribute entirely.
