net: phy: move config symbol MDIO_BUS to drivers/net/phy/Kconfig

2025-09-23T23:56:27+00:00

Config symbol MDIO_BUS isn't used in drivers/net/mdio. It's only used in drivers/net/phy. So move it there. Signed-off-by: Heiner Kallweit Link: https://patch.msgid.link/164ff1c6-2cf9-4e30-80fb-da4cc7165dc8@gmail.com Signed-off-by: Jakub Kicinski

net: phy: micrel: Update Kconfig help text

2025-09-13T00:34:27+00:00

This driver by now supports 17 different Microchip (formerly known as Micrel) chips: KSZ9021, KSZ9031, KSZ9131, KSZ8001, KS8737, KSZ8021, KSZ8031, KSZ8041, KSZ8051, KSZ8061, KSZ8081, KSZ8873MLL, KSZ886X, KSZ9477, LAN8814, LAN8804 and LAN8841. Support for the VSC8201 was removed in commit 51f932c4870f ("micrel phy driver - updated(1)") Update the help text to reflect that, list families instead of models to ease future maintenance.

net: dsa: Move KS8995 to the DSA subsystem

2025-08-19T00:26:09+00:00

By reading the datasheets for the KS8995 it is obvious that this is a 100 Mbit DSA switch. Let us start the refactoring by moving it to the DSA subsystem to preserve development history. Verified that the chip still probes the same after this patch provided CONFIG_HAVE_NET_DSA, CONFIG_NET_DSA and CONFIG_DSA_KS8995 are selected.

net: phy: add driver for MaxLinear MxL86110 PHY

2025-05-27T07:36:17+00:00

Add support for the MaxLinear MxL86110 Gigabit Ethernet PHY, a low-power, cost-optimized transceiver supporting 10/100/1000 Mbps over twisted-pair copper, compliant with IEEE 802.3. The driver implements basic features such as: - Device initialization - RGMII interface timing configuration - Wake-on-LAN support - LED initialization and control via /sys/class/leds This driver has been tested on multiple Variscite boards, including: - VAR-SOM-MX93 (i.MX93) - VAR-SOM-MX8M-PLUS (i.MX8MP) Example boot log showing driver probe: [ 7.692101] imx-dwmac 428a0000.ethernet eth0: PHY [stmmac-0:00] driver [MXL86110 Gigabit Ethernet] (irq=POLL) Signed-off-by: Stefano Radaelli Reviewed-by: Andrew Lunn Link: https://patch.msgid.link/20250521212821.593057-1-stefano.radaelli21@gmail.com Signed-off-by: Paolo Abeni

net: phy: Add support for Aeonsemi AS21xxx PHYs

2025-05-21T22:56:10+00:00

Add support for Aeonsemi AS21xxx 10G C45 PHYs. These PHYs integrate an IPC to setup some configuration and require special handling to sync with the parity bit. The parity bit is a way the IPC use to follow correct order of command sent. Supported PHYs AS21011JB1, AS21011PB1, AS21010JB1, AS21010PB1, AS21511JB1, AS21511PB1, AS21510JB1, AS21510PB1, AS21210JB1, AS21210PB1 that all register with the PHY ID 0x7500 0x7510 before the firmware is loaded. They all support up to 5 LEDs with various HW mode supported. While implementing it was found some strange coincidence with using the same logic for implementing C22 in MMD regs in Broadcom PHYs. For reference here the AS21xxx PHY name logic: AS21x1xxB1 ^ ^^ | |J: Supports SyncE/PTP | |P: No SyncE/PTP support | 1: Supports 2nd Serdes | 2: Not 2nd Serdes support 0: 10G, 5G, 2.5G 5: 5G, 2.5G 2: 2.5G Reviewed-by: Andrew Lunn Signed-off-by: Christian Marangi Link: https://patch.msgid.link/20250517201353.5137-6-ansuelsmth@gmail.com Signed-off-by: Jakub Kicinski

net: phy: make mdio consumer / device layer a separate module

2025-05-20T10:22:47+00:00

After having factored out the provider part from mdio_bus.c, we can make the mdio consumer / device layer a separate module. This also allows to remove Kconfig symbol MDIO_DEVICE. The module init / exit functions from mdio_bus.c no longer have to be called from phy_device.c. The link order defined in drivers/net/phy/Makefile ensures that init / exit functions are called in the right order.

net: phy: remove Kconfig symbol MDIO_DEVRES

2025-05-15T02:12:19+00:00

MDIO_DEVRES is only set where PHYLIB/PHYLINK are set which select MDIO_DEVRES. So we can remove this symbol. Note: Due to circular module dependencies we can't simply make mdio_devres.c part of phylib.
