-Subject: [PATCH] MIPS: lantiq: Add GPHY Firmware loader
-
-Upstream, the GPHY Firmware loader has been merged into the DSA switch
-driver. But we don't use the driver yet, so bring it back.

-+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,xrx200-gphy"
-+ "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>;
-+ };
