The main part of this series is adding handling of the clkout
controls some of the mscc phys have and while at it Andrew
asked for some of the duplicated probe functionality to be
factored out into a common function.

A working config on rockchip/rk3368-lion for example now looks like:

&gmac {
	status = "okay";

	mdio {
		compatible = "snps,dwmac-mdio";
		#address-cells = <1>;
		#size-cells = <0>;

		phy0: phy@0 {
			compatible = "ethernet-phy-id0007.0570";
			reg = <0>;
			assigned-clocks = <&phy0>, <&cru SCLK_MAC>;
			assigned-clock-rates = <125000000>, <125000000>;
			assigned-clock-parents = <0>, <&phy0>;
			clock-output-names = "ext_gmac";
			#clock-cells = <0>;
			vsc8531,edge-slowdown = <7>;
			vsc8531,led-0-mode = <1>;
			vsc8531,led-1-mode = <2>;
		};
	};
};


changes in v5:
- added Andrew's Rb for patch 1
- modified clkout handling to be a clock-provider
  to fit into the existing clock structures
changes in v4:
- fix missing variable initialization in one probe function
changes in v3:
- adapt to 5.8 merge-window results
- introduce a more generic enet-phy-property instead of
  using a vsc8531,* one - suggested by Andrew
changes in v2:
- new probe factoring patch as suggested by Andrew
