Subject: [PATCH 2/2] ARM: dts: lan966x: add support for pcb8309
Date:   Wed, 20 Jul 2022 21:49:04 +0200
Message-ID: <20220720194904.2025384-3-horatiu.vultur@microchip.com>
In-Reply-To: <20220720194904.2025384-1-horatiu.vultur@microchip.com>

Add basic support for pcb8309. It is similar with pcb8291 with one big
difference that is having 2 SFP cages. Therefore it has 4 network ports.
