Message-Id: <E1q0JfS-006Dqc-8t@rmk-PC.armlinux.org.uk> Date: Sat, 20 May 2023 11:18:30 +0100 From: "Russell King (Oracle)" <rmk+kernel@...linux.org.uk> To: Andrew Lunn <andrew@...n.ch>, Heiner Kallweit <hkallweit1@...il.com> Cc: Josua Mayer <josua@...id-run.com>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, netdev@...r.kernel.org Subject: [PATCH net-next] net: sfp: add support for a couple of copper multi-rate modules Add support for the Fiberstore SFP-10G-T and Walsun HXSX-ATRC-1 modules. Internally, the PCB silkscreen has what seems to be a part number of WT_502. Fiberstore use v2.2 whereas Walsun use v2.6. These modules contain a Marvell AQrate AQR113C PHY, accessible through I2C 0x51 using the "rollball" protocol. In both cases, the PHY is programmed to use 10GBASE-R with pause-mode rate adaption. Unlike the other rollball modules, these only need a four second delay before we can talk to the PHY.
