Subject: ARM: dts: stm32: Add nvmem-cells to ethernet nodes for constant mac-addresses
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=998adc8cd5cbd4f45446ab7ad8bc1e1e7b62d7a1;p=users%2Fjedix%2Flinux-maple.git

ARM: dts: stm32: Add nvmem-cells to ethernet nodes for constant mac-addresses

The efuse device tree description already has the two labels pointing to
the efuse nodes that specify the mac-addresses to be used. Wire them up
to the ethernet nodes. This is enough to make barebox pick the right
mac-addresses and pass them to Linux.
