Subject: [PATCH 2/2] ARM: dts: meson8b: odroidc1: use the MAC address stored in the eFuse
Date: Sat, 27 Jul 2019 21:46:47 +0200 [thread overview]
Message-ID: <20190727194647.15355-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190727194647.15355-1-martin.blumenstingl@googlemail.com>
Odroid-C1 (and probably other Meson8b boards which are based on the
reference designs) uses the MAC address stored in eFuse at offset 0x1b4.
Assign the nvmem cell to the Ethernet controller as "mac-address" so the
MAC address which is stored in the eFuse is assigned to the Ethernet
controller. This means the MAC address will be consistent across
reboots.
