[PATCH net-next 0/2] CPSW Bindings for 5000M Fixed-Link

[PATCH net-next 0/2] CPSW Bindings for 5000M Fixed-Link

[Siddharth Vadapalli]

Hello,

This series adds 5000M as a valid speed for fixed-link mode of operation
and also updates the CPSW bindings to evaluate fixed-link property. This
series is in the context of the following device-tree overlay which
enables USXGMII 5000M Fixed-link mode of operation with CPSW on TI's
J784S4 SoC:
https://github.com/torvalds/linux/blob/v6.15-rc1/arch/arm64/boot/dts/ti/k3-j784s4-evm-usxgmii-exp1-exp2.dtso

Series is based on commit
0c49baf099ba r8169: add helper rtl8125_phy_param
of the main branch of net-next tree.

Regards,
Siddharth.

[PATCH net-next 1/2] dt-bindings: net: ethernet-controller: add 5000M speed to fixed-link

[Siddharth Vadapalli]

A link speed of 5000 Mbps is a valid speed for a fixed-link mode of
operation. Hence, update the bindings to include the same.

[PATCH net-next 2/2] dt-bindings: net: ti: k3-am654-cpsw-nuss: evaluate fixed-link property

[Siddharth Vadapalli]

Since the fixed-link (phyless) mode of operation is supported by the
CPSW MAC, include "fixed-link" in the set of properties to be evaluated.

Yes, O.K. Technically any speed is valid for phylink fixed speed. You
could just as well say its a 42Mbps link. But keeping with the speeds
actually defined in 802.3 makes sense.
