dt-bindings: ethernet: eswin: fix hsp-sp-csr backward compatibility

2026-06-04T15:30:37+00:00

Commit c36069c6f46c ("dt-bindings: ethernet: eswin: add optional TXD and
RXD delay register offsets") added two optional cells to eswin,hsp-sp-csr
but omitted minItems: 4.

As a result, dt-schema implicitly required all 6 cells, which broke
backward compatibility with existing 4-cell device trees.

Add minItems: 4 to preserve backward compatibility.

dt-bindings: ethernet: eswin: add optional TXD and RXD delay register offsets

2026-05-21T09:58:16+00:00

Document two optional cells in eswin,hsp-sp-csr for the TXD and RXD
delay control register offsets.

These registers are used by the driver to clear any residual delay
configuration left by the bootloader, ensuring that MAC-side RGMII delay
settings are applied solely according to the kernel configuration.

Add a reference to the EIC7700X SoC Technical Reference Manual for
background information about the HSP CSR block.

dt-bindings: net: document Microchip PIC64-HPSC/HX MDIO controller

2026-04-12T21:19:19+00:00

This MDIO hardware is based on a Microsemi design supported in Linux by
mdio-mscc-miim.c. However, The register interface is completely different
with pic64hpsc, hence the need for separate documentation.

The hardware supports C22 and C45.

The documentation recommends an input clock of 156.25MHz and a prescaler
of 39, which yields an MDIO clock of 1.95MHz.

The hardware supports an interrupt pin to signal transaction completion
which is not strictly needed as the software can also poll a "TRIGGER"
bit for this.

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

2026-04-12T20:51:22+00:00

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: realtek,rtl82xx: Document realtek,*-ssc-enable property

2026-04-10T03:01:52+00:00

Document support for spread spectrum clocking (SSC) on RTL8211F(D)(I)-CG,
RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. Introduce DT properties
'realtek,clkout-ssc-enable', 'realtek,rxc-ssc-enable' and
'realtek,sysclk-ssc-enable' which control CLKOUT, RXC and SYSCLK
SSC spread spectrum clocking enablement on these signals. These
clock are not exposed via the clock API, therefore assigned-clock-sscs
property does not apply.
