| * Altera Triple-Speed Ethernet MAC driver (TSE) |
| |
| Required properties: |
| - compatible: Should be "altr,tse-1.0" for legacy SGDMA based TSE, and should |
| be "altr,tse-msgdma-1.0" for the preferred MSGDMA based TSE. |
| ALTR is supported for legacy device trees, but is deprecated. |
| altr should be used for all new designs. |
| - reg: Address and length of the register set for the device. It contains |
| the information of registers in the same order as described by reg-names |
| - reg-names: Should contain the reg names |
| "control_port": MAC configuration space region |
| "tx_csr": xDMA Tx dispatcher control and status space region |
| "tx_desc": MSGDMA Tx dispatcher descriptor space region |
| "rx_csr" : xDMA Rx dispatcher control and status space region |
| "rx_desc": MSGDMA Rx dispatcher descriptor space region |
| "rx_resp": MSGDMA Rx dispatcher response space region |
| "s1": SGDMA descriptor memory |
| - interrupts: Should contain the TSE interrupts and it's mode. |
| - interrupt-names: Should contain the interrupt names |
| "rx_irq": xDMA Rx dispatcher interrupt |
| "tx_irq": xDMA Tx dispatcher interrupt |
| - rx-fifo-depth: MAC receive FIFO buffer depth in bytes |
| - tx-fifo-depth: MAC transmit FIFO buffer depth in bytes |
| - phy-mode: See ethernet.txt in the same directory. |
| - phy-handle: See ethernet.txt in the same directory. |
| - phy-addr: See ethernet.txt in the same directory. A configuration should |
| include phy-handle or phy-addr. |
| - altr,has-supplementary-unicast: |
| If present, TSE supports additional unicast addresses. |
| Otherwise additional unicast addresses are not supported. |
| - altr,has-hash-multicast-filter: |
| If present, TSE supports a hash based multicast filter. |
| Otherwise, hash-based multicast filtering is not supported. |
| |
| - mdio device tree subnode: When the TSE has a phy connected to its local |
| mdio, there must be device tree subnode with the following |
| required properties: |
| |
| - compatible: Must be "altr,tse-mdio". |
| - #address-cells: Must be <1>. |
| - #size-cells: Must be <0>. |
| |
| For each phy on the mdio bus, there must be a node with the following |
| fields: |
| |
| - reg: phy id used to communicate to phy. |
| - device_type: Must be "ethernet-phy". |
| |
| The MAC address will be determined using the optional properties defined in |
| ethernet.txt. |
| |
