Subject: [PATCH v3 26/28] misc: lan966x_pci: Add dtsi/dtso nodes in order to support SFPs
Date: Fri, 13 Jun 2025 15:48:06 +0200 [thread overview]
Message-ID: <20250613134817.681832-27-herve.codina@bootlin.com> (raw)
In-Reply-To: <20250613134817.681832-1-herve.codina@bootlin.com>
Add device-tree nodes needed to support SFPs.
Those nodes are:
- the clock controller
- the i2c controller
- the i2c mux
- the SFPs themselves and their related ports in the switch
