net: dsa: add basic initial driver for MxL862xx switches

2026-02-11T10:27:58Z

Add very basic DSA driver for MaxLinear's MxL862xx switches. In contrast to previous MaxLinear switches the MxL862xx has a built-in processor that runs a sophisticated firmware based on Zephyr RTOS. Interaction between the host and the switch hence is organized using a software API of that firmware rather than accessing hardware registers directly. Add descriptions of the most basic firmware API calls to access the built-in MDIO bus hosting the 2.5GE PHYs, basic port control as well as setting up the CPU port. Implement a very basic DSA driver using that API which is sufficient to get packets flowing between the user ports and the CPU port. The firmware offers all features one would expect from a modern switch hardware, they are going to be added one by one in follow-up patch series.

net: dsa: yt921x: Add support for Motorcomm YT921x

2025-10-22T01:25:30Z

Motorcomm YT921x is a series of ethernet switches developed by Shanghai Motorcomm Electronic Technology, including: - YT9215S / YT9215RB / YT9215SC: 5 GbE PHYs - YT9213NB / YT9214NB: 2 GbE PHYs - YT9218N / YT9218MB: 8 GbE PHYs and up to 2 GMACs. Driver verified on a stock wireless router with IPQ5018 + YT9215S. Signed-off-by: David Yang Link: https://patch.msgid.link/20251017060859.326450-4-mmyangfl@gmail.com Signed-off-by: Jakub Kicinski

net: dsa: dsa_loop: remove usage of mdio_board_info

2025-09-17T22:24:01Z

dsa_loop is the last remaining user of mdio_board_info. Let's remove using mdio_board_info, so that support for it can be dropped from phylib.

net: dsa: lantiq_gswip: move to dedicated folder

2025-09-03T00:45:42Z

Move the lantiq_gswip driver to its own folder and update MAINTAINERS file accordingly. This is done ahead of extending the driver to support the MaxLinear GSW1xx series of standalone switch ICs, which includes adding a bunch of files.

net: dsa: Move KS8995 to the DSA subsystem

2025-08-19T00:26:09Z

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: dsa: mt7530: introduce driver for MT7988 built-in switch

2023-04-03T09:13:01Z

Add driver for the built-in Gigabit Ethernet switch which can be found in the MediaTek MT7988 SoC. The switch shares most of its design with MT7530 and MT7531, but has it's registers mapped into the SoCs register space rather than being connected externally or internally via MDIO. Introduce a new platform driver to support that. Signed-off-by: Daniel Golle Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: mt7530: introduce separate MDIO driver

2023-04-03T09:13:00Z

Split MT7530 switch driver into a common part and a part specific for MDIO connected switches and multi-chip modules. Move MDIO-specific functions to newly introduced mt7530-mdio.c while keeping the common parts in mt7530.c. Introduce new Kconfig symbol CONFIG_NET_DSA_MT7530_MDIO which is implied by CONFIG_NET_DSA_MT7530. Signed-off-by: Daniel Golle Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: rzn1-a5psw: add Renesas RZ/N1 advanced 5 port switch driver

2022-06-27T10:37:55Z

Add Renesas RZ/N1 advanced 5 port switch driver. This switch handles 5 ports including 1 CPU management port. A MDIO bus is also exposed by this switch and allows to communicate with PHYs connected to the ports. Each switch port (except for the CPU management ports) is connected to the MII converter. This driver includes basic bridging support, more support will be added later (vlan, etc).
