2023-06-05net: mdio: Introduce a regmap-based mdio driverMaxime Chevallier1-0/+11
There exists several examples today of devices that embed an ethernet PHY or PCS directly inside an SoC. In this situation, either the device is controlled through a vendor-specific register set, or sometimes exposes the standard 802.3 registers that are typically accessed over MDIO. As phylib and phylink are designed to use mdiodevices, this driver allows creating a virtual MDIO bus, that translates mdiodev register accesses to regmap accesses. The reason we use regmap is because there are at least 3 such devices known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is exposed over SPI. Signed-off-by: Maxime Chevallier <[email protected]> Reviewed-by: Simon Horman <[email protected]> Signed-off-by: David S.

2023-04-12net: ethernet: Add missing depends on MDIO_DEVRESAndrew Lunn1-0/+3
A number of MDIO drivers make use of devm_mdiobus_alloc_size(). This is only available when CONFIG_MDIO_DEVRES is enabled. Add missing depends or selects, depending on if there are circular dependencies or not. This avoids linker errors, especially for randconfig builds.

2021-06-11net: mdiobus: Introduce fwnode_mdiobus_register_phy()Calvin Johnson1-0/+7
Introduce fwnode_mdiobus_register_phy() to register PHYs on the mdiobus. From the compatible string, identify whether the PHY is c45 and based on this create a PHY device instance which is registered on the mdiobus. Along with fwnode_mdiobus_register_phy() also introduce fwnode_find_mii_timestamper() and fwnode_mdiobus_phy_device_register() since they are needed. While at it, also use the newly introduced fwnode operation in of_mdiobus_phy_device_register().

Move all the MDIO drivers and multiplexers into drivers/net/mdio. The mdio core is however left in the phy directory, due to mutual dependencies between the MDIO core and the PHY core. Take this opportunity to sort the Kconfig based on the menuconfig strings, and move the multiplexers to the end with a separating comment. v2: Fix typo in commit message Acked-by: Florian Fainelli <[email protected]> Signed-off-by: Andrew Lunn <[email protected]> Signed-off-by: David S.
