net: phy: add a Kconfig option for mdio_devres

2020-07-07T22:37:02+00:00

If phylib is built as a module and CONFIG_MDIO_DEVICE is 'y', the mdio_device and mdio_bus code will be in the phylib module, not in the kernel image. Meanwhile we build mdio_devres depending on the CONFIG_MDIO_DEVICE symbol, so if it's 'y', it will go into the kernel and we'll hit the following linker error: ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_alloc_size': >> drivers/net/phy/mdio_devres.c:38: undefined reference to `mdiobus_alloc_size' ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_free': >> drivers/net/phy/mdio_devres.c:16: undefined reference to `mdiobus_free' ld: drivers/net/phy/mdio_devres.o: in function `__devm_mdiobus_register': >> drivers/net/phy/mdio_devres.c:87: undefined reference to `__mdiobus_register' ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_unregister': >> drivers/net/phy/mdio_devres.c:53: undefined reference to `mdiobus_unregister' ld: drivers/net/phy/mdio_devres.o: in function `devm_of_mdiobus_register': >> drivers/net/phy/mdio_devres.c:120: undefined reference to `of_mdiobus_register' Add a hidden Kconfig option for MDIO_DEVRES which will be currently selected by CONFIG_PHYLIB as there are no non-phylib users of these helpers.

of: mdio: provide devm_of_mdiobus_register()

2020-06-30T22:57:34+00:00

Implement a managed variant of of_mdiobus_register(). We need to make mdio_devres into its own module because otherwise we'd hit circular sumbol dependencies between phylib and of_mdio. Signed-off-by: Bartosz Golaszewski Signed-off-by: David S. Miller

phy: un-inline devm_mdiobus_register()

2020-06-30T22:57:34+00:00

Functions should only be static inline if they're very short. This devres helper is already over 10 lines and it will grow soon as we'll be improving upon its approach. Pull it into mdio_devres.c. Signed-off-by: Bartosz Golaszewski Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: add Broadcom BCM54140 support

2020-04-22T19:14:18+00:00

The Broadcom BCM54140 is a Quad SGMII/QSGMII Copper/Fiber Gigabit Ethernet transceiver. This also adds support for tunables to set and get downshift and energy detect auto power-down. The PHY has four ports and each port has its own PHY address. There are per-port registers as well as global registers. Unfortunately, the global registers can only be accessed by reading and writing from/to the PHY address of the first port. Further, there is no way to find out what port you actually are by just reading the per-port registers. We therefore, have to scan the bus on the PHY probe to determine the port and thus what address we need to access the global registers.

net: phy: move the mscc driver to its own directory

2020-03-15T04:06:45+00:00

The MSCC PHY driver is growing, with lots of space consuming features (firmware support, full initialization, MACsec...). It's becoming hard to read and navigate in its source code. This patch moves the MSCC driver to its own directory, without modifying anything, as a preparation for splitting up its features into dedicated files.

Synopsys DesignWare XPCS is an MMD that can manage link status, auto-negotiation, link training, ... In this commit we add basic support for XPCS using USXGMII interface and Clause 73 Auto-negotiation. This is highly tied with PHYLINK and can't be used without it.

net: add helpers to resolve negotiated flow control

2020-02-17T03:39:44+00:00

Add a couple of helpers to resolve negotiated flow control. Two helpers are provided: - linkmode_resolve_pause() which takes the link partner and local advertisements, and decodes whether we should enable TX or RX pause at the MAC. This is useful outside of phylib, e.g. in phylink. - phy_get_pause(), which returns the TX/RX enablement status for the current negotiation results of the PHY. This allows us to centralise the flow control resolution, rather than spreading it around. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
