From: hongbo wang <redacted> some use cases want to use swp4-eno2 link as ordinary data path, so we can enable swp5 as dsa master, the data from kernel can be transmitted to eno3, then send to swp5 via internal link, switch will forward it to swp0-3. the data to kernel will come from swp0-3, and received by kernel via swp5-eno3 link.

You will end up with two DT blobs with the same top level compatible. This is going to cause confusion. I suggest you add an additional top level compatible to make it clear this differs from the compatible = "fsl,ls1028a-rdb", "fsl,ls1028a" blob. Andrew
