APM X-Gene SoC Ethernet nodes
|
||
|
|
|
||
|
|
Ethernet nodes are defined to describe on-chip ethernet interfaces in
|
||
|
|
APM X-Gene SoC.
|
||
|
|
|
||
|
|
Required properties for all the ethernet interfaces:
|
||
|
|
- compatible: Should be "apm,xgene-enet"
|
||
|
|
- reg: Address and length of the register set for the device. It contains the
|
||
|
|
information of registers in the same order as described by reg-names
|
||
|
|
- reg-names: Should contain the register set names
|
||
|
|
- "enet_csr": Ethernet control and status register address space
|
||
|
|
- "ring_csr": Descriptor ring control and status register address space
|
||
|
|
- "ring_cmd": Descriptor ring command register address space
|
||
|
|
- interrupts: Ethernet main interrupt
|
||
|
|
- clocks: Reference to the clock entry.
|
||
|
|
- local-mac-address: MAC address assigned to this device
|
||
|
|
- phy-connection-type: Interface type between ethernet device and PHY device
|
||
|
|
|
||
|
|
Required properties for ethernet interfaces that have external PHY:
|
||
|
|
- phy-handle: Reference to a PHY node connected to this device
|
||
|
|
|
||
|
|
- mdio: Device tree subnode with the following required properties:
|
||
|
|
- compatible: Must be "apm,xgene-mdio".
|
||
|
|
- #address-cells: Must be <1>.
|
||
|
|
- #size-cells: Must be <0>.
|
||
|
|
|
||
|
|
For the phy on the mdio bus, there must be a node with the following fields:
|
||
|
|
- compatible: PHY identifier. Please refer ./phy.txt for the format.
|
||
|
|
- reg: The ID number for the phy.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok".
|
||
|
|
|
||
|
|
Example:
|
||
|
|
menetclk: menetclk {
|
||
|
|
compatible = "apm,xgene-device-clock";
|
||
|
|
clock-output-names = "menetclk";

||
|
|
status = "ok";
|
||
|
|
};

|
||
|
|
compatible = "apm,xgene-enet";

status = "disabled";

<0x0 0X17030000 0x0 0X400>,
|
||
|
|
<0x0 0X10000000 0x0 0X200>;
