Hi.
Now I use marvell switch 88e6165 (6-port) and try to connect with MDIO and RGMII2 interface AM335x.
This task is very complex. Because i must to write DTS file for linux kernel and use driver for 88e6165.
Linux kernel have driver 88e6165 in /drivers/net/dsa/mv88e6123_61_65.c. But this code have very more bugs. These bugs in driver we fixed.
I know about work AM335x only in PHY mode with extended switch.
Now we have problems with DTS file. Ready-made solution i have not found. So we hand make DTS file. I doubt very much the correctness our linux DTS file.

May be somebody have right DTS file for marvell 88e6165 switch?
