Kernel-3.10.0-957.el7_fsl-fec

  • Freescale Fast Ethernet Controller (FEC)

Required properties:

  • compatible : Should be “fsl,-fec”
  • reg : Address and length of the register set for the device
  • interrupts : Should contain fec interrupt
  • phy-mode : String, operation mode of the PHY interface.
    Supported values are: “mii”, “gmii”, “sgmii”, “tbi”, “rmii”,
    “rgmii”, “rgmii-id”, “rgmii-rxid”, “rgmii-txid”, “rtbi”, “smii”.

Optional properties:

  • local-mac-address : 6 bytes, mac address
  • phy-reset-gpios : Should specify the gpio for phy reset
  • phy-reset-duration : Reset duration in milliseconds. Should present
    only if property “phy-reset-gpios” is available. Missing the property
    will have the duration be 1 millisecond. Numbers greater than 1000 are
    invalid and 1 millisecond will be used instead.

Example:

ethernet@83fec000 {
compatible = “fsl,imx51-fec”, “fsl,imx27-fec”;
reg = <0x83fec000 0x4000>;
interrupts = <87>;
phy-mode = “mii”;
phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
local-mac-address = [00 04 9F 01 1B B9];
};
