   1 Lantiq XWAY SoC GPHY binding
   2 ============================
   3
   4 This binding describes a software-defined ethernet PHY, provided by the RCU
   5 module on newer Lantiq XWAY SoCs (xRX200 and newer).

   8 Required properties:
   9 - compatible            : Should be one of
  10                                 "lantiq,xrx200a1x-gphy"
  11                                 "lantiq,xrx200a2x-gphy"
  12                                 "lantiq,xrx300-gphy"
  13                                 "lantiq,xrx330-gphy"
  14 - reg                   : Addrress of the GPHY FW load address register
  15 - resets                : Must reference the RCU GPHY reset bit
  16 - reset-names           : One entry, value must be "gphy" or optional "gphy2"
  17 - clocks                : A reference to the (PMU) GPHY clock gate
  18
  19 Optional properties:
  20 - lantiq,gphy-mode      : GPHY_MODE_GE (default) or GPHY_MODE_FE as defined in
  21                           <dt-bindings/mips/lantiq_xway_gphy.h>

  25 Example for the GPHys on the xRX200 SoCs:
  26
  27 #include <dt-bindings/mips/lantiq_rcu_gphy.h>
  28         gphy0: gphy@20 {
  29                 compatible = "lantiq,xrx200a2x-gphy";
  30                 reg = <0x20 0x4>;
  31
  32                 resets = <&reset0 31 30>, <&reset1 7 7>;
  33                 reset-names = "gphy", "gphy2";
  34                 clocks = <&pmu0 XRX200_PMU_GATE_GPHY>;
  35                 lantiq,gphy-mode = <GPHY_MODE_GE>;
  36         };
