Merge branch 'BCM53xx-driver' 

Florian Fainelli says:

====================
net: dsa: Broadcom BCM53xx switches support

This patch series adds support for the Broadcom BCM53xx series aka RoboSwitches.

This driver is largely based on Jonas Gorski's b53 driver for OpenWrt which can
be found here:

https://dev.openwrt.org/browser/trunk/target/linux/generic/files/drivers/net/phy/b53



a few bug fixes and DSA-ifycation later, here is what we got.

This has been successfully tested in the following configurations:

- Broadcom BCM53011 using the SRAB bus layer with 4 ports LAN, 1 port WAN

- A Broadcom BCM7445 device with an internal Starfighter 2 switch (bcm_sf2.c)
  and a Broadcom BCM53125 hanging off one of its ports connected via MDIO, creating
  two trees hanging off each other, and this works!

- A Broadcom BCM53125 MDIO connected to a Lamobo/Bananapi R1 board using the STMMAC
  MDIO driver

For now, we do not enable Broadcom tags, because there are different
generations of switches being supported which have different tag formats, but
the plan is to enable them later on.

Support for different HW features will be added later: EEE, Compact Field
Processor (TCAM) once this initial cut gets accepted.

Testing and bug reports welcome!

Broadcom BCM53xx Ethernet switches

==================================



Required properties:



- compatible: For external switch chips, compatible string must be exactly one

  of: "brcm,bcm5325"

      "brcm,bcm53115"

      "brcm,bcm53125"

      "brcm,bcm53128"

      "brcm,bcm5365"

      "brcm,bcm5395"

      "brcm,bcm5397"

      "brcm,bcm5398"



  For the BCM5310x SoCs with an integrated switch, must be one of:

      "brcm,bcm53010-srab"

      "brcm,bcm53011-srab"

      "brcm,bcm53012-srab"

      "brcm,bcm53018-srab"

      "brcm,bcm53019-srab" and the mandatory "brcm,bcm5301x-srab" string



  For the BCM63xx/33xx SoCs with an integrated switch, must be one of:

      "brcm,bcm3384-switch"

      "brcm,bcm6328-switch"

      "brcm,bcm6368-switch" and the mandatory "brcm,bcm63xx-switch"



See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional

required and optional properties.



Examples:



Ethernet switch connected via MDIO to the host, CPU port wired to eth0:



	eth0: ethernet@10001000 {

		compatible = "brcm,unimac";

		reg = <0x10001000 0x1000>;



		fixed-link {

			speed = <1000>;

			duplex-full;

		};

	};



	mdio0: mdio@10000000 {

		compatible = "brcm,unimac-mdio";

		#address-cells = <1>;

		#size-cells = <0>;



		switch0: ethernet-switch@30 {

			compatible = "brcm,bcm53125";

			#address-cells = <1>;

			#size-cells = <0>;



			ports {

				port0@0 {

					reg = <0>;

					label = "lan1";

				};



				port1@1 {

					reg = <1>;

					label = "lan2";

				};



				port5@5 {

					reg = <5>;

					label = "cable-modem";

					fixed-link {

						speed = <1000>;

						duplex-full;

					};

					phy-mode = "rgmii-txid";

				};



				port8@8 {

					reg = <8>;

					label = "cpu";

					fixed-link {

						speed = <1000>;

						duplex-full;

					};

					phy-mode = "rgmii-txid";

					ethernet = <&eth0>;

				};

			};

		};

	};
