1 * Freescale Fast Ethernet Controller (FEC)
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
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-reset-active-high : If present then the reset sequence using the GPIO
16 specified in the "phy-reset-gpios" property is reversed (H=reset state,
18 - phy-supply : regulator that powers the Ethernet PHY.
19 - phy-handle : phandle to the PHY device connected to this device.
20 - fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
21 Use instead of phy-handle.
22 - fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
23 hw multi queues. Should specify the tx queue number, otherwise set tx queue
25 - fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
26 hw multi queues. Should specify the rx queue number, otherwise set rx queue
28 - fsl,magic-packet : If present, indicates that the hardware supports waking
32 - mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
33 according to phy.txt in the same directory
