   1 * Freescale Fast Ethernet Controller (FEC)
   2
   3 Required properties:
   4 - compatible : Should be "fsl,<soc>-fec"
   5 - reg : Address and length of the register set for the device
   6 - interrupts : Should contain fec interrupt
   7 - phy-mode : See ethernet.txt file in the same directory
   8
   9 Optional properties:
  10 - phy-reset-gpios : Should specify the gpio for phy reset
  11 - phy-reset-duration : Reset duration in milliseconds.  Should present
  12   only if property "phy-reset-gpios" is available.  Missing the property
  13   will have the duration be 1 millisecond.  Numbers greater than 1000 are
  14   invalid and 1 millisecond will be used instead.
  15 - phy-supply : regulator that powers the Ethernet PHY.
  16 - phy-handle : phandle to the PHY device connected to this device.
  17 - fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
  18   Use instead of phy-handle.
  19 - fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
  20   hw multi queues. Should specify the tx queue number, otherwise set tx queue
  21   number to 1.
  22 - fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
  23   hw multi queues. Should specify the rx queue number, otherwise set rx queue
  24   number to 1.
  25 - fsl,magic-packet : If present, indicates that the hardware supports waking
  26   up via magic packet.
  27
  28 Optional subnodes:
  29 - mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
  30   according to phy.txt in the same directory
  31
  32 Example:
  33
  34 ethernet@83fec000 {
  35         compatible = "fsl,imx51-fec", "fsl,imx27-fec";
  36         reg = <0x83fec000 0x4000>;
  37         interrupts = <87>;
  38         phy-mode = "mii";
  39         phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
  40         local-mac-address = [00 04 9F 01 1B B9];
  41         phy-supply = <&reg_fec_supply>;
  42 };
  43
  44 Example with phy specified:
  45
  46 ethernet@83fec000 {
  47         compatible = "fsl,imx51-fec", "fsl,imx27-fec";
  48         reg = <0x83fec000 0x4000>;
  49         interrupts = <87>;
  50         phy-mode = "mii";
  51         phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
  52         local-mac-address = [00 04 9F 01 1B B9];
  53         phy-supply = <&reg_fec_supply>;
  54         phy-handle = <&ethphy>;
  55         mdio {
  56                 ethphy: ethernet-phy@6 {
  57                         compatible = "ethernet-phy-ieee802.3-c22";
  58                         reg = <6>;
  59                         max-speed = <100>;
  60                 };
  61         };
  62 };
