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 | ||
