Hi netdev, Recently I had been working on implementing DSA driver for MaxLinear GSW145 switch. Here is my initial draft. Before proceeding futher, I am hoping to get comments and cooperation as early/many as possible. On my hand, I have an arm64 board with one GSW145 chip being connected via MDIO management interface. According to the public datasheet of GSW145, the chip itself on my board is in self-start (PS_NOWAIT=1b), managed switch (PS_OP_MD=11) mode. On this board, only two slave ethernet ports (port0, port1) of this chip are enabled. As its datasheet says, this chip supports MDIO, SPI, UART management interfaces in many operation modes (self-start/non-self-start, managed/standalone). Unfortunately it is impossible for me to run this draft on all of these combinations. It will be very helpful if anyone can help to run it on different hardware setups and send the feedback back to me. I also noticed that lantiq_gswip.c looks similar as gsw145. I have no access to the datasheet of the chip this file supports. Maybe they can be merged together.
