[PATCH 2/2] arm64: dts: mt7986: add port@5 as CPU port

From: Arınç ÜNAL via B4 Relay
Date: Mon Feb 19 2024 - 04:36:45 EST


From: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>

On MediaTek MT7986b RFB and MediaTek MT7986a RFB, port 5 of the MT7531
switch is connected to the second MAC of the SoC as a CPU port. Add the
port and set up the second MAC on the bindings.
