1 | * Altera Triple-Speed Ethernet MAC driver (TSE) |
2 | ||
3 | Required properties: | |
4 | - compatible: Should be "altr,tse-1.0" for legacy SGDMA based TSE, and should | |
5 | be "altr,tse-msgdma-1.0" for the preferred MSGDMA based TSE. | |
6 | ALTR is supported for legacy device trees, but is deprecated. | |
7 | altr should be used for all new designs. | |
8 | - reg: Address and length of the register set for the device. It contains | |
9 | the information of registers in the same order as described by reg-names | |
10 | - reg-names: Should contain the reg names | |
11 | "control_port": MAC configuration space region | |
12 | "tx_csr": xDMA Tx dispatcher control and status space region | |
13 | "tx_desc": MSGDMA Tx dispatcher descriptor space region | |
14 | "rx_csr" : xDMA Rx dispatcher control and status space region | |
15 | "rx_desc": MSGDMA Rx dispatcher descriptor space region | |
16 | "rx_resp": MSGDMA Rx dispatcher response space region | |
17 | "s1": SGDMA descriptor memory | |
18 | - interrupts: Should contain the TSE interrupts and it's mode. | |
19 | - interrupt-names: Should contain the interrupt names | |
20 | "rx_irq": xDMA Rx dispatcher interrupt | |
21 | "tx_irq": xDMA Tx dispatcher interrupt | |
22 | - rx-fifo-depth: MAC receive FIFO buffer depth in bytes | |
23 | - tx-fifo-depth: MAC transmit FIFO buffer depth in bytes | |
24 | - phy-mode: See ethernet.txt in the same directory. | |
25 | - phy-handle: See ethernet.txt in the same directory. | |
26 | - phy-addr: See ethernet.txt in the same directory. A configuration should | |
27 | include phy-handle or phy-addr. | |
28 | - altr,has-supplementary-unicast: | |
29 | If present, TSE supports additional unicast addresses. | |
30 | Otherwise additional unicast addresses are not supported. | |
31 | - altr,has-hash-multicast-filter: | |
32 | If present, TSE supports a hash based multicast filter. | |
33 | Otherwise, hash-based multicast filtering is not supported. | |
34 | ||
35 | - mdio device tree subnode: When the TSE has a phy connected to its local | |
36 | mdio, there must be device tree subnode with the following | |
37 | required properties: | |
38 | ||
39 | - compatible: Must be "altr,tse-mdio". | |
40 | - #address-cells: Must be <1>. | |
41 | - #size-cells: Must be <0>. | |
42 | ||
43 | For each phy on the mdio bus, there must be a node with the following | |
44 | fields: | |
45 | ||
46 | - reg: phy id used to communicate to phy. | |
47 | - device_type: Must be "ethernet-phy". | |
48 | ||
49 | Optional properties: | |
50 | - local-mac-address: See ethernet.txt in the same directory. | |
51 | - max-frame-size: See ethernet.txt in the same directory. | |
52 | ||
