net: dsa: yt921x: Add support for Motorcomm YT921x

2025-10-22T01:25:30+00:00

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

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

2025-09-03T00:45:42+00:00

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

2025-08-19T00:26:09+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: dsa: mt7530: introduce driver for MT7988 built-in switch

2023-04-03T09:13:01+00:00

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

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

2022-06-27T10:37:55+00:00

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).

net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VC

2021-10-18T13:02:56+00:00

This patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port 10/100/1000M switch controller. The driver has been developed based on a GPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c found in the OpenWrt source tree. Despite the name, the RTL8365MB-VC has an entirely different register layout to the already-supported RTL8366RB ASIC. Notwithstanding this, the structure of the rtl8365mb subdriver is loosely based on the rtl8366rb subdriver. Like the 'rb, it establishes its own irqchip to handle cascaded PHY link status interrupts. The RTL8365MB-VC switch is capable of offloading a large number of features from the software, but this patch introduces only the most basic DSA driver functionality. The ports always function as standalone ports, with bridging handled in software. One more thing. Realtek's nomenclature for switches makes it hard to know exactly what other ASICs might be supported by this driver. The vendor driver goes by the name rtl8367c, but as far as I can tell, no chip actually exists under this name. As such, the subdriver is named rtl8365mb to emphasize the potentially limited support. But it is clear from the vendor sources that a number of other more advanced switches share a similar register layout, and further support should not be too hard to add given access to the relevant hardware. With this in mind, the subdriver has been written with as few assumptions about the particular chip as is reasonable. But the RTL8365MB-VC is the only hardware I have available, so some further work is surely needed.
