From c7f75954212b5e64f6b1f2375215b02fd79758ce Mon Sep 17 00:00:00 2001
From: Martin Schiller <ms@dev.tdt.de>

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.

-Lantiq GSWIP Ethernet switches
-==================================
-
-Required properties for GSWIP core:
-
-- compatible : "lantiq,xrx200-gswip" for the embedded GSWIP in the
- xRX200 SoC
- "lantiq,xrx300-gswip" for the embedded GSWIP in the
- xRX300 SoC
- "lantiq,xrx330-gswip" for the embedded GSWIP in the
- xRX330 SoC
-- reg : memory range of the GSWIP core registers
- : memory range of the GSWIP MDIO registers
- : memory range of the GSWIP MII registers
-
-See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of
-additional required and optional properties.
-
-
-Required properties for MDIO bus:
-- compatible : "lantiq,xrx200-mdio" for the MDIO bus inside the GSWIP
- core of the xRX200 SoC and the PHYs connected to it.
-
-See Documentation/devicetree/bindings/net/mdio.txt for a list of additional
-required and optional properties.
-
-
-Required properties for GPHY firmware loading:
-- compatible : "lantiq,xrx200-gphy-fw", "lantiq,gphy-fw"
- "lantiq,xrx300-gphy-fw", "lantiq,gphy-fw"
- "lantiq,xrx330-gphy-fw", "lantiq,gphy-fw"
- for the loading of the firmware into the embedded
- GPHY core of the SoC.
-- lantiq,rcu : reference to the rcu syscon
-
-The GPHY firmware loader has a list of GPHY entries, one for each
-embedded GPHY
-
-- reg : Offset of the GPHY firmware register in the RCU
- register range
-- resets : list of resets of the embedded GPHY
-- reset-names : list of names of the resets
