This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.

* 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.
|
|
|
|
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>;
|
|
};
