Subject: [PATCH net-next 01/12] dt-bindings: net: cdns,macb: add Mobileye
 EyeQ5 ethernet interface

Add "cdns,eyeq5-gem" as compatible for the integrated GEM block inside
Mobileye EyeQ5 SoCs. It is different from other compatibles in two main
ways: (1) it requires a generic PHY and (2) it is better to keep TCP
Segmentation Offload (TSO) disabled.
