From e1bebf97815158f16da96f69e9d9bb891a4c69eb Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 25 Oct 2021 22:10:18 +0100 Subject: arm64: dts: apple: j274: Expose PCI node for the Ethernet MAC address At the moment, all the Minis running Linux have the same MAC address (00:10:18:00:00:00), which is a bit annoying. Expose the PCI node corresponding to the Ethernet device, and declare a 'local-mac-address' property. The bootloader will update it (m1n1 already has the required feature). And if it doesn't, then the default value is already present in the DT. This relies on forcing the bus number for each port so that the endpoints connected to them are correctly numbered (and keeps dtc quiet).
