Subject: [PATCH 5/6] dt-bindings: nvmem: u-boot,env: add MAC's #nvmem-cell-cells
Date: Tue, 10 Jan 2023 11:54:24 +0100	[thread overview]

U-Boot's "ethaddr" environment variable is very often used to store
*base* MAC address. It's used as a base for calculating addresses for
multiple interfaces. It's done by adding proper values. Actual offsets
are picked by manufacturers and vary across devices.
