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

2026-05-23T11:04:25+00:00

[ Upstream commit 600f01dc4bd0c736b3ffea9f7976136d8bf1b136 ] 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: Fix Tegra234 MGBE PTP clock

2026-04-22T11:18:52+00:00

[ Upstream commit fb22b1fc5bca3c0aad95388933497ceb30f1fb26 ] The PTP clock for the Tegra234 MGBE device is incorrectly named 'ptp-ref' and should be 'ptp_ref'. This is causing the following warning to be observed on Tegra234 platforms that use this device: ERR KERN tegra-mgbe 6800000.ethernet eth0: Invalid PTP clock rate WARNING KERN tegra-mgbe 6800000.ethernet eth0: PTP init failed Although this constitutes an ABI breakage in the binding for this device, PTP support has clearly never worked and so fix this now so we can correct the device-tree for this device. Note that the MGBE driver still supports the legacy 'ptp-ref' clock name and so older/existing device-trees will still work, but given that this is not the correct name, there is no point to advertise this in the binding.

dt-bindings: net: fec: add pps channel property

commit 1aa772be0444a2bd06957f6d31865e80e6ae4244 upstream. Add fsl,pps-channel property to select where to connect the PPS signal. This depends on the internal SoC routing and on the board, for example on the i.MX8 SoC it can be connected to an external pin (using channel 1) or to internal eDMA as DMA request (channel 0).

2024-10-16T01:23:53+00:00

The MDIO block in the BCM6846 is not identical to any of the previous versions, but has extended registers not present in the other variants. For this reason we need to use a new compatible especially for this SoC.

dt-bindings: net: xlnx,axi-ethernet: Add missing reg minItems

2024-10-03T10:15:04+00:00

Add missing reg minItems as based on current binding document only ethernet MAC IO space is a supported configuration. There is a bug in schema, current examples contain 64-bit addressing as well as 32-bit addressing. The schema validation does pass incidentally considering one 64-bit reg address as two 32-bit reg address entries. If we change axi_ethernet_eth1 example node reg addressing to 32-bit schema validation reports: Documentation/devicetree/bindings/net/xlnx,axi-ethernet.example.dtb: ethernet@40000000: reg: [[1073741824, 262144]] is too short To fix it add missing reg minItems constraints and to make things clearer stick to 32-bit addressing in examples.
