We are starting on board bringup of a design referenced off the LS1021a-IOT board. I am now trying to bring up our 2 ethernet SGMII links on our custom hardware. We have no phys and will be connecting in one case to a Marvell
1Gbit SW and to a second LS1021a chip in the other. My question concerns the proper DTS config needed.
From what I've read it appears that I need to remove phy-handle, and phy-connection-type properties and add a fixed-link config. If someone has worked in this area recently Id appreciate your opinion on the DTB entries and what more might be needed.
