1* Altera Triple-Speed Ethernet MAC driver (TSE) 2 3Required 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 49The MAC address will be determined using the optional properties defined in 50ethernet.txt. 51 52Example: 53 54 tse_sub_0_eth_tse_0: ethernet@1,00000000 { 55 compatible = "altr,tse-msgdma-1.0"; 56 reg = <0x00000001 0x00000000 0x00000400>, 57 <0x00000001 0x00000460 0x00000020>, 58 <0x00000001 0x00000480 0x00000020>, 59 <0x00000001 0x000004A0 0x00000008>, 60 <0x00000001 0x00000400 0x00000020>, 61 <0x00000001 0x00000420 0x00000020>; 62 reg-names = "control_port", "rx_csr", "rx_desc", "rx_resp", "tx_csr", "tx_desc"; 63 interrupt-parent = <&hps_0_arm_gic_0>; 64 interrupts = <0 41 4>, <0 40 4>; 65 interrupt-names = "rx_irq", "tx_irq"; 66 rx-fifo-depth = <2048>; 67 tx-fifo-depth = <2048>; 68 address-bits = <48>; 69 max-frame-size = <1500>; 70 local-mac-address = [ 00 00 00 00 00 00 ]; 71 phy-mode = "gmii"; 72 altr,has-supplementary-unicast; 73 altr,has-hash-multicast-filter; 74 phy-handle = <&phy0>; 75 mdio { 76 compatible = "altr,tse-mdio"; 77 #address-cells = <1>; 78 #size-cells = <0>; 79 phy0: ethernet-phy@0 { 80 reg = <0x0>; 81 device_type = "ethernet-phy"; 82 }; 83 84 phy1: ethernet-phy@1 { 85 reg = <0x1>; 86 device_type = "ethernet-phy"; 87 }; 88 89 }; 90 }; 91 92 tse_sub_1_eth_tse_0: ethernet@1,00001000 { 93 compatible = "altr,tse-msgdma-1.0"; 94 reg = <0x00000001 0x00001000 0x00000400>, 95 <0x00000001 0x00001460 0x00000020>, 96 <0x00000001 0x00001480 0x00000020>, 97 <0x00000001 0x000014A0 0x00000008>, 98 <0x00000001 0x00001400 0x00000020>, 99 <0x00000001 0x00001420 0x00000020>; 100 reg-names = "control_port", "rx_csr", "rx_desc", "rx_resp", "tx_csr", "tx_desc"; 101 interrupt-parent = <&hps_0_arm_gic_0>; 102 interrupts = <0 43 4>, <0 42 4>; 103 interrupt-names = "rx_irq", "tx_irq"; 104 rx-fifo-depth = <2048>; 105 tx-fifo-depth = <2048>; 106 address-bits = <48>; 107 max-frame-size = <1500>; 108 local-mac-address = [ 00 00 00 00 00 00 ]; 109 phy-mode = "gmii"; 110 altr,has-supplementary-unicast; 111 altr,has-hash-multicast-filter; 112 phy-handle = <&phy1>; 113 };
