These patches need to rely on the yt8531 phy driver of motorcomm company and the corresponding clock delay configuration to work normally, and the yt8531 phy driver is being submitted. I have applied the motorcomm patchs during my test on board v1.2b, so the ethernet cannot work without the application of the motorcomm patchs. For the patchs of yt8531, see [1] 1 - https://patchwork.kernel.org/project/netdevbpf/cover/20230202030037.9075-1-Frank.Sae@xxxxxxxxxxxxxx/ Thanks, Yanhong.
