Hisilicon hip04 Ethernet Controller
* Ethernet controller node
Required properties:
- compatible: should be "hisilicon,hip04-mac".
- reg: address and length of the register set for the device.
- interrupts: interrupt for the device.
- port-handle: <phandle port channel>
phandle, specifies a reference to the syscon ppe node
port, port number connected to the controller
channel, recv channel start from channel * number (RX_DESC_NUM)
group, field in the pkg desc, in general, it is the same as the port.
- phy-mode: see ethernet.txt [1].
Optional properties:
- phy-handle: see ethernet.txt [1].
[1] Documentation/devicetree/bindings/net/ethernet.txt
* Ethernet ppe node:
Control rx & tx fifos of all ethernet controllers.
Have 2048 recv channels shared by all ethernet controllers, only if no overlap.
Each controller's recv channel start from channel * number (RX_DESC_NUM).
Required properties:
- compatible: "hisilicon,hip04-ppe", "syscon".
- reg: address and length of the register set for the device.
* MDIO bus node:
Required properties:
- compatible: should be "hisilicon,mdio".
- Inherits from MDIO bus node binding [2]
[2] Documentation/devicetree/bindings/net/phy.txt
Example:
mdio {
compatible = "hisilicon,mdio";
reg = <0x28f1000 0x1000>;
#address-cells = <1>;
#size-cells = <0>;
phy0: ethernet-phy@0 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <0>;
marvell,reg-init = <18 0x14 0 0x8001>;
};
phy1: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
marvell,reg-init = <18 0x14 0 0x8001>;
};
};
ppe: ppe@28c0000 {
compatible = "hisilicon,hip04-ppe", "syscon";
reg = <0x28c0000 0x10000>;
};
