dt-bindings: net: dsa: lantiq,gswip: use correct node name

2026-01-27T10:52:44Z

Ethernet PHYs should use nodes named 'ethernet-phy@'. Rename the Ethernet PHY nodes in the example to comply.

dt-bindings: net: dsa: lantiq,gswip: add MaxLinear R(G)MII slew rate

2026-01-19T18:08:24Z

Add new maxlinear,slew-rate-txc and maxlinear,slew-rate-txd uint32 properties. The properties are only applicable for ports in R(G)MII mode and allow for slew rate reduction in comparison to "normal" default configuration with the purpose to reduce radiated emissions.

dt-bindings: net: dsa: microchip: Make pinctrl 'reset' optional

2026-01-09T02:00:18Z

Commit e469b87e0fb0d ("dt-bindings: net: dsa: microchip: Add strap description to set SPI mode") required both 'default' and 'reset' pinctrl states for all compatible devices. However, this requirement should be only applicable to KSZ8463. Make the 'reset' pinctrl state optional for all other Microchip DSA devices while keeping it mandatory for KSZ8463. Fix below CHECK_DTBS warnings: arch/arm64/boot/dts/freescale/imx8mp-skov-basic.dtb: switch@5f (microchip,ksz9893): pinctrl-names: ['default'] is too short from schema $id: http://devicetree.org/schemas/net/dsa/microchip,ksz.yaml# Signed-off-by: Frank Li Reviewed-by: Marco Felsch Reviewed-by: Rob Herring (Arm) Link: https://patch.msgid.link/20260106143620.126212-1-Frank.Li@nxp.com Signed-off-by: Jakub Kicinski

dt-bindings: net: dsa: lantiq,gswip: add support for MaxLinear GSW1xx switches

2025-11-06T22:16:17Z

Extend the Lantiq GSWIP device tree binding to also cover MaxLinear GSW1xx switches which are based on the same hardware IP but connected via MDIO instead of being memory-mapped. Add compatible strings for MaxLinear GSW120, GSW125, GSW140, GSW141, and GSW145 switches and adjust the schema to handle the different connection methods with conditional properties. Add MaxLinear GSW125 example showing MDIO-connected configuration.

dt-bindings: net: dsa: lantiq,gswip: add support for MII delay properties

2025-11-06T22:16:17Z

Add support for standard tx-internal-delay-ps and rx-internal-delay-ps properties on port nodes to allow fine-tuning of RGMII clock delays. The GSWIP switch hardware supports delay values in 500 picosecond increments from 0 to 3500 picoseconds, with a post-reset default of 2000 picoseconds for both TX and RX delays. The driver currently sets the delay to 0 in case the PHY is setup to carry out the delay by the corresponding interface modes ("rgmii-id", "rgmii-rxid", "rgmii-txid"). This corresponds to the driver changes that allow adjusting MII delays using Device Tree properties instead of relying solely on the PHY interface mode.
