[PATCH v3 1/2] devicetree: add binding for Aurora VLSI NB8800 Ethernet controller

This adds a binding for the Aurora VLSI NB8800 Ethernet controller
using the "aurora,nb8800" compatible string. When used in Sigma
Designs chips a few additional features are available. These variants
are indicated by a "sigma,<chip>-ethernet" compatible string.

+* Aurora VLSI AU-NB8800 Ethernet controller
+
+Required properties:
+- compatible: Should be "sigma,<chip>-ethernet", "aurora,nb8800"
+- reg: Should be MMIO address space of the device
+- interrupts: Should contain the interrupt specifier for the device
+- interrupt-parent: Should be a phandle for the interrupt controller
+- clocks: Should be a phandle for the clock for the device
+- #address-cells: Should be <1>
+- #size-cells: Should be <0>
+
+Common properties described in ethernet.txt:
+- local-mac-address
+- mac-address
+- phy-handle
+- phy-mode
+
+The attached PHY should be specified in a child node as per phy.txt.
+
+Example:
+
+ethernet@26000 {
+ compatible = "sigma,smp8642-ethernet", "aurora,nb8800";
+ reg = <0x26000 0x800>;
+ interrupts = <38>;
+ clocks = <&sys_clk>;
+ max-speed = <1000>;
+ phy-connection-type = "rgmii";
+ phy-handle = <&eth0_phy>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ eth0_phy: ethernet-phy@1 {
+ compatible = "ethernet-phy-ieee802.3-c22";
+ reg = <1>;
+ };
+};
