-* 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-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,err006687-workaround-present: If present indicates that the system has
- the hardware workaround for ERR006687 applied and does not need a software
- workaround.
-- fsl,stop-mode: register bits of stop mode control, the format is
- <&gpr req_gpr req_bit>.
- gpr is the phandle to general purpose register node.
- req_gpr is the gpr register offset for ENET stop request.
- req_bit is the gpr bit offset for ENET stop request.
- -interrupt-names: names of the interrupts listed in interrupts property in
- the same order. The defaults if not specified are
- __Number of interrupts__ __Default__
- 1 "int0"
- 2 "int0", "pps"
- 3 "int0", "int1", "int2"
- 4 "int0", "int1", "int2", "pps"
- The order may be changed as long as they correspond to the interrupts
- property. Currently, only i.mx7 uses "int1" and "int2". They correspond to
- tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
- For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
- per second interrupt associated with 1588 precision time protocol(PTP).
-
-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
-
-Deprecated optional properties:
- To avoid these, create a phy node according to phy.txt in the same
- directory, and point the fec's "phy-handle" property to it. Then use
- the phy's reset binding, again described by phy.txt.
-- 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-reset-active-high : If present then the reset sequence using the GPIO
- specified in the "phy-reset-gpios" property is reversed (H=reset state,
- L=operation state).
-- phy-reset-post-delay : Post reset delay in milliseconds. If present then
- a delay of phy-reset-post-delay milliseconds will be observed after the
- phy-reset-gpios has been toggled. Can be omitted thus no delay is
- observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.
-
-Example:
-
-ethernet@83fec000 {
- compatible = "fsl,imx51-fec", "fsl,imx27-fec";
- reg = <0x83fec000 0x4000>;
- interrupts = <87>;
- phy-mode = "mii";
- phy-reset-gpios = <&gpio2 14 GPIO_ACTIVE_LOW>; /* GPIO2_14 */
- local-mac-address = [00 04 9F 01 1B B9];
- phy-supply = <&reg_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 GPIO_ACTIVE_LOW>; /* GPIO2_14 */
- local-mac-address = [00 04 9F 01 1B B9];
- phy-supply = <&reg_fec_supply>;
- phy-handle = <&ethphy>;
- mdio {
- clock-frequency = <5000000>;
- ethphy: ethernet-phy@6 {
- compatible = "ethernet-phy-ieee802.3-c22";
- reg = <6>;
- max-speed = <100>;
- };
- };
-};
