1Hisilicon hip04 Ethernet Controller
2
3* Ethernet controller node
4
5Required properties:
6- compatible: should be "hisilicon,hip04-mac".
7- reg: address and length of the register set for the device.
8- interrupts: interrupt for the device.
9- port-handle: <phandle port channel>
10	phandle, specifies a reference to the syscon ppe node
11	port, port number connected to the controller
12	channel, recv channel start from channel * number (RX_DESC_NUM)
13	group, field in the pkg desc, in general, it is the same as the port.
14- phy-mode: see ethernet.txt [1].
15
16Optional properties:
17- phy-handle: see ethernet.txt [1].

22* Ethernet ppe node:
23Control rx & tx fifos of all ethernet controllers.
24Have 2048 recv channels shared by all ethernet controllers, only if no overlap.
25Each controller's recv channel start from channel * number (RX_DESC_NUM).
26
27Required properties:
28- compatible: "hisilicon,hip04-ppe", "syscon".
29- reg: address and length of the register set for the device.

32* MDIO bus node:
33
34Required properties:
35
36- compatible: should be "hisilicon,mdio".
37- Inherits from MDIO bus node binding [2]
