+Qualcomm Technologies EMAC Gigabit Ethernet Controller
+
+This network controller consists of two devices: a MAC and an SGMII
+internal PHY. Each device is represented by a device tree node. A phandle
+connects the MAC node to its corresponding internal phy node. Another
+phandle points to the external PHY node.
+
+Required properties:
+
+MAC node:
+- compatible : Should be "qcom,fsm9900-emac".
+- reg : Offset and length of the register regions for the device
+- interrupts : Interrupt number used by this controller
+- mac-address : The 6-byte MAC address. If present, it is the default
+ MAC address.
+- internal-phy : phandle to the internal PHY node
+- phy-handle : phandle the the external PHY node
+
+Internal PHY node:
+- compatible : Should be "qcom,fsm9900-emac-sgmii" or "qcom,qdf2432-emac-sgmii".
+- reg : Offset and length of the register region(s) for the device
+- interrupts : Interrupt number used by this controller
+
+The external phy child node:
+- reg : The phy address
+
