| * 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 |
| - max-speed: see ethernet.txt file in the same directory. |
| - phy: see ethernet.txt file in the same directory. |
| |
| Clock handling: |
| The clock frequency is needed to calculate and set polling period of EMAC. |
| It must be provided by one of: |
| - clock-frequency: CPU frequency. |
| - clocks: reference to the clock supplying the 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: |
| |
| ethernet@c0fc2000 { |
| compatible = "snps,arc-emac"; |
| reg = <0xc0fc2000 0x3c>; |
| interrupts = <6>; |
| mac-address = [ 00 11 22 33 44 55 ]; |
| |
| clock-frequency = <80000000>; |
| /* or */ |
| clocks = <&emac_clock>; |
| |
| max-speed = <100>; |
| phy = <&phy0>; |
| |
| #address-cells = <1>; |
| #size-cells = <0>; |
| phy0: ethernet-phy@0 { |
| reg = <1>; |
| }; |
| }; |
