1* Freescale Fast Ethernet Controller (FEC) 2 3Required 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 : String, operation mode of the PHY interface. 8 Supported values are: "mii", "gmii", "sgmii", "tbi", "rmii", 9 "rgmii", "rgmii-id", "rgmii-rxid", "rgmii-txid", "rtbi", "smii". 10 11Optional properties: 12- local-mac-address : 6 bytes, mac address 13- phy-reset-gpios : Should specify the gpio for phy reset 14- phy-reset-duration : Reset duration in milliseconds. Should present 15 only if property "phy-reset-gpios" is available. Missing the property 16 will have the duration be 1 millisecond. Numbers greater than 1000 are 17 invalid and 1 millisecond will be used instead. 18 19Example: 20 21ethernet@83fec000 { 22 compatible = "fsl,imx51-fec", "fsl,imx27-fec"; 23 reg = <0x83fec000 0x4000>; 24 interrupts = <87>; 25 phy-mode = "mii"; 26 phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */ 27 local-mac-address = [00 04 9F 01 1B B9]; 28}; 29
