Subject: [PATCH net-next 2/3] net: bcmgenet: Pass "main" clock down to the MDIO driver
Date: Fri, 16 Feb 2024 10:42:36 -0800 [thread overview]
Message-ID: <20240216184237.259954-3-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20240216184237.259954-1-florian.fainelli@broadcom.com>
GENET has historically had to create a MDIO platform device for its
controller and pass some auxiliary data to it, like a MDIO completion
callback. Now we also pass the "main" clock to allow for the MDIO bus
controller to manage that clock adequately around I/O accesses.
