| * Freescale Fast Ethernet Controller (FEC) |
| |
| Required properties: |
| - compatible : Should be "fsl,<soc>-fec" |
| - reg : Address and length of the register set for the device |
| - interrupts : Should contain fec interrupt |
| - phy-mode : See ethernet.txt file in the same directory |
| |
| Optional properties: |
| - 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. |
| - phy-supply : regulator that powers the Ethernet PHY. |
| - phy-handle : phandle to the PHY device connected to this device. |
| - fixed-link : Assume a fixed link. See fixed-link.txt in the same directory. |
| Use instead of phy-handle. |
| - fsl,num-tx-queues : The property is valid for enet-avb IP, which supports |
| hw multi queues. Should specify the tx queue number, otherwise set tx queue |
| number to 1. |
| - fsl,num-rx-queues : The property is valid for enet-avb IP, which supports |
| hw multi queues. Should specify the rx queue number, otherwise set rx queue |
| number to 1. |
| - fsl,magic-packet : If present, indicates that the hardware supports waking |
| up via magic packet. |
| - fsl,wakeup_irq : The property define the wakeup irq index in enet irq source. |
| - stop-mode : If present, indicates soc need to set gpr bit to request stop |
| mode. |
| |
| Optional subnodes: |
| - mdio : specifies the mdio bus in the FEC, used as a container for phy nodes |
| according to phy.txt in the same directory |
| |
| 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]; |
| phy-supply = <®_fec_supply>; |
| }; |
| |
| Example with phy specified: |
| |
| 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]; |
| phy-supply = <®_fec_supply>; |
| phy-handle = <ðphy>; |
| mdio { |
| ethphy: ethernet-phy@6 { |
| compatible = "ethernet-phy-ieee802.3-c22"; |
| reg = <6>; |
| max-speed = <100>; |
| }; |
| }; |
| }; |
