1* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC) 2 3Required properties: 4- compatible: Should be "snps,arc-emac" 5- reg: Address and length of the register set for the device 6- interrupts: Should contain the EMAC interrupts 7- clock-frequency: CPU frequency. It is needed to calculate and set polling 8period of EMAC. 9- max-speed: see ethernet.txt file in the same directory. 10- phy: see ethernet.txt file in the same directory. 11 12Child nodes of the driver are the individual PHY devices connected to the 13MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus. 14 15Examples: 16 17 ethernet@c0fc2000 { 18 compatible = "snps,arc-emac"; 19 reg = <0xc0fc2000 0x3c>; 20 interrupts = <6>; 21 mac-address = [ 00 11 22 33 44 55 ]; 22 clock-frequency = <80000000>; 23 max-speed = <100>; 24 phy = <&phy0>; 25 26 #address-cells = <1>; 27 #size-cells = <0>; 28 phy0: ethernet-phy@0 { 29 reg = <1>; 30 }; 31 }; 32
