====================
net: dsa: lantiq_gswip: code improvements

This patchset for the lantiq_gswip driver is a collection of minor fixes
and coding improvements by Martin Blumenstingl without any real changes
in the actual functionality.

-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
-
