Kernel-4.18.0-80.el8_rcu-gphy

Lantiq XWAY SoC GPHY binding

This binding describes a software-defined ethernet PHY, provided by the RCU
module on newer Lantiq XWAY SoCs (xRX200 and newer).

---

Required properties:

• compatible : Should be one of

            "lantiq,xrx200a1x-gphy"
            "lantiq,xrx200a2x-gphy"
            "lantiq,xrx300-gphy"
            "lantiq,xrx330-gphy"
  

• reg : Addrress of the GPHY FW load address register
• resets : Must reference the RCU GPHY reset bit
• reset-names : One entry, value must be “gphy” or optional “gphy2”
• clocks : A reference to the (PMU) GPHY clock gate

Optional properties:

• lantiq,gphy-mode : GPHY_MODE_GE (default) or GPHY_MODE_FE as defined in

          <dt-bindings/mips/lantiq_xway_gphy.h>

Example for the GPHys on the xRX200 SoCs:

#include <dt-bindings/mips/lantiq_rcu_gphy.h>
gphy0: gphy@20 {
compatible = “lantiq,xrx200a2x-gphy”;
reg = <0x20 0x4>;

    resets = <&reset0 31 30>, <&reset1 7 7>;
    reset-names = "gphy", "gphy2";
    clocks = <&pmu0 XRX200_PMU_GATE_GPHY>;
    lantiq,gphy-mode = <GPHY_MODE_GE>;
};
