|
|
|
This documents dwmmac based ethernet device which supports Gigabit |
|
ethernet for version v2.3.0 onwards. |
|
|
|
This device has following properties: |
|
|
|
Required properties: |
|
|
|
- compatible: Should be qcom,qcs404-ethqos" |
|
|
|
- reg: Address and length of the register set for the device |
|
|
|
- reg-names: Should contain register names "stmmaceth", "rgmii" |
|
|
|
- clocks: Should contain phandle to clocks |
|
|
|
- clock-names: Should contain clock names "stmmaceth", "pclk", |
|
"ptp_ref", "rgmii" |
|
|
|
- interrupts: Should contain phandle to interrupts |
|
|
|
- interrupt-names: Should contain interrupt names "macirq", "eth_lpi" |
|
|
|
Rest of the properties are defined in stmmac.txt file in same directory |
