1 | Hisilicon hip04 Ethernet Controller |
| 2 | ||
| 3 | * Ethernet controller node | |
| 4 | ||
| 5 | Required 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 | - phy-mode: see ethernet.txt [1]. | |
| 14 | ||
| 15 | Optional properties: | |
| 16 | - phy-handle: see ethernet.txt [1]. | |

| 18 | [1] Documentation/devicetree/bindings/net/ethernet.txt | |
| 19 | ||
| 20 | ||
| 21 | * Ethernet ppe node: | |
| 22 | Control rx & tx fifos of all ethernet controllers. | |
| 23 | Have 2048 recv channels shared by all ethernet controllers, only if no overlap. | |
| 24 | Each controller's recv channel start from channel * number (RX_DESC_NUM). | |
| 25 | ||
| 26 | Required properties: | |
| 27 | - compatible: "hisilicon,hip04-ppe", "syscon". | |
| 28 | - reg: address and length of the register set for the device. | |
| 29 | ||
| 30 | ||
| 31 | * MDIO bus node: | |
| 32 | ||
| 33 | Required properties: | |
| 34 | ||
| fc7e37c6 | 35 | - compatible: should be "hisilicon,mdio". |
