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