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-reset-post-delay : Post reset delay in milliseconds. If present then
19 a delay of phy-reset-post-delay milliseconds will be observed after the
20 phy-reset-gpios has been toggled. Can be omitted thus no delay is
21 observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.
22 - phy-supply : regulator that powers the Ethernet PHY.
23 - phy-handle : phandle to the PHY device connected to this device.
24 - fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
25 Use instead of phy-handle.
26 - fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
27 hw multi queues. Should specify the tx queue number, otherwise set tx queue
29 - fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
30 hw multi queues. Should specify the rx queue number, otherwise set rx queue
32 - fsl,magic-packet : If present, indicates that the hardware supports waking
34 - fsl,err006687-workaround-present: If present indicates that the system has
35 the hardware workaround for ERR006687 applied and does not need a software
37 -interrupt-names: names of the interrupts listed in interrupts property in
38 the same order. The defaults if not specified are
39 __Number of interrupts__ __Default__
42 3 "int0", "int1", "int2"
43 4 "int0", "int1", "int2", "pps"
44 The order may be changed as long as they correspond to the interrupts
45 property. Currently, only i.mx7 uses "int1" and "int2". They correspond to
46 tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
47 For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
48 per second interrupt associated with 1588 precision time protocol(PTP).
52 - mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
53 according to phy.txt in the same directory
