zynq and marvell dsa 88e6176 integration, device tree

Hi,

We have custom board that based on zynq7000 SoC and petalinux is v2017.4. We have been trying to up ethernet solution for those zynq board.

The board has marvell PHY which are connected to PS MIO (gem0).

After some search on webs and device tree modifications, we just configure the device tree like this solution(https://forums.xilinx.com/t5/Embedded-Linux/zynq-and-marvell-dsa-88e6352-integration-device-tree/td-p/779400) and more data that we finded, that not help much.

We have a "no phy found" error.

Our board setup:

|————————————————————|              |——————————————————————————————————————————|
|     e000b000, GEM0—|———— RGMII ———|—port6 (0x16,act as MAC)        port1 —— PHY1
| Zynq-7000          |              |    mv88e6176 (switch1@addr=2)            |
|     e000c000, GEM1 |              | port5 (disabled)               port3 —— PHY3(other ports is not used)
