+Intel Platform Controller Hub (PCH) GigaBit Ethernet (GBE)
+
+Required properties:
+- compatible: Should be the PCI vendor & device ID, eg. "pci8086,8802".
+- reg: Should be a PCI device number as specified by the PCI bus
+ binding to IEEE Std 1275-1994.
+- phy-reset-gpios: Should be a GPIO list containing a single GPIO that
+ resets the attached PHY when active.
+
+Example:
+
+ eg20t_mac@2,0,1 {
+ compatible = "pci8086,8802";
+ reg = <0x00020100 0 0 0 0>;
+ phy-reset-gpios = <&eg20t_gpio 6
+ GPIO_ACTIVE_LOW>;
+ };
+
+ eg20t_gpio: eg20t_gpio@2,0,2 {
+ compatible = "pci8086,8803";
+ reg = <0x00020200 0 0 0 0>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
Introduce documentation for a device tree binding for the Intel Platform Controller Hub (PCH) GigaBit Ethernet (GBE) device. Although this is a PCIe device & thus largely auto-detectable, this binding will be used to provide the driver with the PHY reset GPIO.
