Subject: [PATCH 731/768] dt-bindings: net: dsa: lantiq_gswip: Add missing
phy-mode and fixed-link
The CPU port has to specify a phy-mode and either a phy or a fixed-link.
Since GSWIP is connected using a SoC internal protocol there's no PHY
involved. Add phy-mode = "internal" and a fixed-link to describe the
communication between the PMAC (Ethernet controller) and GSWIP switch.

Subject: dt-bindings: net: dsa: lantiq,gswip: convert to YAML schema
Convert the lantiq,gswip bindings to YAML format.
Also add this new file to the MAINTAINERS file.
Furthermore, the CPU port has to specify a phy-mode and either a phy or
a fixed-link. Since GSWIP is connected using a SoC internal protocol
there's no PHY involved. Add phy-mode = "internal" and a fixed-link to
the example code to describe the communication between the PMAC
(Ethernet controller) and GSWIP switch.

Date: Tue, 11 Jun 2024 15:54:24 +0200
Subject: net: dsa: lantiq_gswip: Only allow phy-mode = "internal" on the CPU
port
Add the CPU port to gswip_xrx200_phylink_get_caps() and
gswip_xrx300_phylink_get_caps(). It connects through a SoC-internal bus,
so the only allowed phy-mode is PHY_INTERFACE_MODE_INTERNAL.

Subject: net: dsa: lantiq_gswip: Don't manually call gswip_port_enable()
We don't need to manually call gswip_port_enable() from within
gswip_setup() for the CPU port. DSA does this automatically for us.
