* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
|
|
|
|
|
|
|
|
|
|
Required properties:
|
|
|
|
|
- compatible: Should be "snps,arc-emac"
|
|
|
|
|
- reg: Address and length of the register set for the device
|
|
|
|
|
- interrupts: Should contain the EMAC interrupts
|
|
|
|
|
- clock-frequency: CPU frequency. It is needed to calculate and set polling
|
|
|
|
|
period of EMAC.

Child nodes of the driver are the individual PHY devices connected to the
|
|
|
|
|
MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.

Examples:
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
compatible = "snps,arc-emac";
|
|
|
|
|
reg = <0xc0fc2000 0x3c>;
|
|
|
|
|
interrupts = <6>;
|
|
|
|
|
mac-address = [ 00 11 22 33 44 55 ];
|
|
|
|
|
clock-frequency = <80000000>;
|
|
|
|
|
max-speed = <100>;
|
|
|
|
|
phy = <&phy0>;
|
|
|
|
|
|
|
|
|
|
#address-cells = <1>;
|
|
|
|
|
#size-cells = <0>;
|
|
|
|
|
phy0: ethernet-phy@0 {
|
|
|

};
