Subject: [PATCH net-next v2 0/2] net: dsa: ks8995: Fix up bindings

After looking at the datasheets for KS8995 I realized this is
a DSA switch and need to have DT bindings as such and be implemented
as such.

This series just fixes up the bindings and the offending device tree.

The existing kernel driver which is in drivers/net/phy/spi_ks8995.c
does not implement DSA. It can be forgiven for this because it was
merged in 2011 and the DSA framework was not widely established
back then. It continues to probe fine but needs to be rewritten
to use the special DSA tag and moved to drivers/net/dsa as time
permits. (I hope I can do this.)

It's fine for the networking tree to merge both patches, I maintain
ixp4xx as well. But I can also carry the second patch through the
SoC tree if so desired.

Changes in v2:
- The device ports are MII and not RGMII (copy/paste error...)
- Document the elusive "port 5" which is a separate PHY inside the
  KS8995 usually used for "WAN" ports in home routers.
- Include a verbose example with a switch-facing ethernet MII and
  a WAN-facing MII for the port 5 PHY in the DT binding.
- Link to v1: https://lore.kernel.org/r/20250624-ks8995-dsa-bindings-v1-0-71a8b4f63315@linaro.org
