-Subject: [PATCH 25/29] net: mv643xx_eth: add DT parsing support
-
-This adds device tree parsing support for the shared driver of mv643xx_eth.
-As the bindings are slightly different from current PPC bindings new binding
-documentation is also added. Following PPC-style device setup, the shared
-driver now also adds port platform_devices and sets up port platform_data.

-+Marvell Orion/Discovery ethernet controller
-+=============================================
-+
-+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
-+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
-+Discovery system controller chips (mv64[345]60).
-+
-+The Discovery ethernet controller is described with two levels of nodes. The
-+first level describes the ethernet controller itself and the second level
-+describes up to 3 ethernet port nodes within that controller. The reason for
-+the multiple levels is that the port registers are interleaved within a single
-+set of controller registers. Each port node describes port-specific properties.
-+
-+Note: The above separation is only true for Discovery system controllers.
-+For Orion SoCs we stick to the separation, although there each controller has
-+only one port associated. Multiple ports are implemented as multiple single-port
-+controllers. As Kirkwood has some issues with proper initialization after reset,
-+an extra compatible string is added for it.
-+
-+* Ethernet controller node
-+
-+Required controller properties:
-+ - #address-cells: shall be 1.
-+ - #size-cells: shall be 0.
-+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
-+ - reg: address and length of the controller registers.
-+
-+Optional controller properties:
-+ - clocks: phandle reference to the controller clock.
-+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
-+
-+* Ethernet port node
-+
-+Required port properties:
-+ - device_type: shall be "network".
-+ - compatible: shall be one of "marvell,orion-eth-port",
-+ "marvell,kirkwood-eth-port".
-+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
-+ - interrupts: port interrupt.
-+ - local-mac-address: 6 bytes MAC address.
-+
-+Optional port properties:
-+ - marvell,tx-queue-size: size of the transmit ring buffer.
-+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
-+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
-+ - marvell,rx-queue-size: size of the receive ring buffer.
-+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
-+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
-+
-+and
-+
-+ - phy-handle: phandle reference to ethernet PHY.
-+
-+or
-+
-+ - speed: port speed if no PHY connected.
-+ - duplex: port mode if no PHY connected.
-+
-+* Node example:
-+
-+mdio-bus {
-+ ...
-+ ethphy: ethernet-phy@8 {
-+ device_type = "ethernet-phy";
-+ ...
-+ };
-+};
-+
-+eth: ethernet-controller@72000 {
-+ compatible = "marvell,orion-eth";
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+ reg = <0x72000 0x2000>;
-+ clocks = <&gate_clk 2>;
-+ marvell,tx-checksum-limit = <1600>;
-+
-+ ethernet@0 {
-+ device_type = "network";
-+ compatible = "marvell,orion-eth-port";
-+ reg = <0>;
-+ interrupts = <29>;
-+ phy-handle = <&ethphy>;
-+ local-mac-address = [00 00 00 00 00 00];
-+ };
-+};
