    1 Lantiq GSWIP Ethernet switches
    2 ==================================
    3 
    4 Required properties for GSWIP core:
    5 
    6 - compatible    : "lantiq,xrx200-gswip" for the embedded GSWIP in the
    7                   xRX200 SoC
    8                   "lantiq,xrx300-gswip" for the embedded GSWIP in the
    9                   xRX300 SoC
   10                   "lantiq,xrx330-gswip" for the embedded GSWIP in the
   11                   xRX330 SoC
   12 - reg           : memory range of the GSWIP core registers
   13                 : memory range of the GSWIP MDIO registers
   14                 : memory range of the GSWIP MII registers
   15 
   16 See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of
   17 additional required and optional properties.
   18 
   19 
   20 Required properties for MDIO bus:
   21 - compatible    : "lantiq,xrx200-mdio" for the MDIO bus inside the GSWIP
   22                   core of the xRX200 SoC and the PHYs connected to it.
   23 
   24 See Documentation/devicetree/bindings/net/mdio.txt for a list of additional
   25 required and optional properties.
   26 
   27 
   28 Required properties for GPHY firmware loading:
   29 - compatible    : "lantiq,xrx200-gphy-fw", "lantiq,gphy-fw"
   30                   "lantiq,xrx300-gphy-fw", "lantiq,gphy-fw"
   31                   "lantiq,xrx330-gphy-fw", "lantiq,gphy-fw"
   32                   for the loading of the firmware into the embedded
   33                   GPHY core of the SoC.
   34 - lantiq,rcu    : reference to the rcu syscon
   35 
   36 The GPHY firmware loader has a list of GPHY entries, one for each
   37 embedded GPHY
   38 
   39 - reg           : Offset of the GPHY firmware register in the RCU
   40                   register range
   41 - resets        : list of resets of the embedded GPHY
   42 - reset-names   : list of names of the resets
   43 
   44 Example:
   45 
   46 Ethernet switch on the VRX200 SoC:
