|
|
|
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 one of:
|
|
"qcom,qcs404-ethqos"
|
|
"qcom,sm8150-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
|
