dt-bindings: net: dsa: nxp,sja1105: make spi-cpol optional for sja1110

2026-04-12T20:51:22Z

Currently, the binding requires 'spi-cpha' for SJA1105 and 'spi-cpol' for SJA1110. However, the SJA1110 supports both SPI modes 0 and 2. Mode 2 (cpha=0, cpol=1) is used by the NXP LX2160 Bluebox 3. On the SolidRun i.MX8DXL HummingBoard Telematics, mode 0 is stable, while forcing mode 2 introduces CRC errors especially during bursts. Drop the requirement on spi-cpol for SJA1110.

dt-bindings: net: dsa: maxlinear,mxl862xx: remove port label

2026-03-05T00:40:36Z

The ports in the example device tree should not have a 'label' property. Labels for all user ports have been removed from an earlier submission, but this was overlooked in the case of the CPU port. Remove 'cpu' port label from the example.

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
