Subject: [PATCH net-next 1/3] dt-bindings: net: add nvmem-mac-address-offset property
Date: Wed, 14 Apr 2021 17:26:55 +0200 [thread overview]
Message-ID: <20210414152657.12097-2-michael@walle.cc> (raw)
In-Reply-To: <20210414152657.12097-1-michael@walle.cc>
It is already possible to read the MAC address via a NVMEM provider. But
there are boards, esp. with many ports, which only have a base MAC
address stored. Thus we need to have a way to provide an offset per
network device.
