Add Linux device tree related to Meta (Facebook) Ventura specific
devices connected to the BMC (AST2600) SoC. The purpose of Ventura is to
detect liquid leakage from all compute trays, switch trays and rack
sensors within the rack, log the events, and take necessary actions
accordingly.

What is on the other end of this fixed link?

If there are no devices on the bus, why enable it?

The other end of this fixed link is the CPU port of a Marvell 88E6393X
switch. We are using this switch in unmanaged mode rather than using
the DSA subsystem. Therefore, we use a fixed-link to force the mac3 to
100Mbps full-duplex RMII to match the CPU port configuration.

We intentionally enable it so user-space tools can access the switch
registers. I have added a comment in v13 to clarify this.

You are mixing up terms. The 88E6393X does not have a dedicated port
for connecting to the host CPU. Any port can be connected to the host,
using DSA tags. And all the ports are 1G or faster, so it seems odd to
limit it to 100Mbps. There is something consider a CPU port, but that
connects the internal Z80 CPU to the switch fabric.

Why would user space want to access the switch registers for an
unmanaged switch? It sounds like you are using Marvells SDK in
userspace to manage the switch, rather than using DSA.
