1* Marvell Armada 375 Ethernet Controller (PPv2.1) 2 Marvell Armada 7K/8K Ethernet Controller (PPv2.2) 3 Marvell CN913X Ethernet Controller (PPv2.3) 4 5Required properties: 6 7- compatible: should be one of: 8 "marvell,armada-375-pp2" 9 "marvell,armada-7k-pp2" 10- reg: addresses and length of the register sets for the device. 11 For "marvell,armada-375-pp2", must contain the following register 12 sets: 13 - common controller registers 14 - LMS registers 15 - one register area per Ethernet port 16 For "marvell,armada-7k-pp2" used by 7K/8K and CN913X, must contain the following register 17 sets: 18 - packet processor registers 19 - networking interfaces registers 20 - CM3 address space used for TX Flow Control 21 22- clocks: pointers to the reference clocks for this device, consequently: 23 - main controller clock (for both armada-375-pp2 and armada-7k-pp2) 24 - GOP clock (for both armada-375-pp2 and armada-7k-pp2) 25 - MG clock (only for armada-7k-pp2) 26 - MG Core clock (only for armada-7k-pp2) 27 - AXI clock (only for armada-7k-pp2) 28- clock-names: names of used clocks, must be "pp_clk", "gop_clk", "mg_clk", 29 "mg_core_clk" and "axi_clk" (the 3 latter only for armada-7k-pp2). 30 31The ethernet ports are represented by subnodes. At least one port is 32required. 33 34Required properties (port): 35 36- interrupts: interrupt(s) for the port 37- port-id: ID of the port from the MAC point of view 38- gop-port-id: only for marvell,armada-7k-pp2, ID of the port from the 39 GOP (Group Of Ports) point of view. This ID is used to index the 40 per-port registers in the second register area. 41- phy-mode: See ethernet.txt file in the same directory 42 43Optional properties (port): 44 45- marvell,loopback: port is loopback mode 46- phy: a phandle to a phy node defining the PHY address (as the reg 47 property, a single integer). 48- interrupt-names: if more than a single interrupt for is given, must be the 49 name associated to the interrupts listed. Valid names are: 50 "hifX", with X in [0..8], and "link". The names "tx-cpu0", 51 "tx-cpu1", "tx-cpu2", "tx-cpu3" and "rx-shared" are supported 52 for backward compatibility but shouldn't be used for new 53 additions. 54- marvell,system-controller: a phandle to the system controller. 55 56Example for marvell,armada-375-pp2: 57 58ethernet@f0000 { 59 compatible = "marvell,armada-375-pp2"; 60 reg = <0xf0000 0xa000>, 61 <0xc0000 0x3060>, 62 <0xc4000 0x100>, 63 <0xc5000 0x100>; 64 clocks = <&gateclk 3>, <&gateclk 19>; 65 clock-names = "pp_clk", "gop_clk"; 66 67 eth0: eth0@c4000 { 68 interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>; 69 port-id = <0>; 70 phy = <&phy0>; 71 phy-mode = "gmii"; 72 }; 73 74 eth1: eth1@c5000 { 75 interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>; 76 port-id = <1>; 77 phy = <&phy3>; 78 phy-mode = "gmii"; 79 }; 80}; 81 82Example for marvell,armada-7k-pp2: 83 84cpm_ethernet: ethernet@0 { 85 compatible = "marvell,armada-7k-pp22"; 86 reg = <0x0 0x100000>, <0x129000 0xb000>, <0x220000 0x800>; 87 clocks = <&cpm_syscon0 1 3>, <&cpm_syscon0 1 9>, 88 <&cpm_syscon0 1 5>, <&cpm_syscon0 1 6>, <&cpm_syscon0 1 18>; 89 clock-names = "pp_clk", "gop_clk", "mg_clk", "mg_core_clk", "axi_clk"; 90 91 eth0: eth0 { 92 interrupts = <ICU_GRP_NSR 39 IRQ_TYPE_LEVEL_HIGH>, 93 <ICU_GRP_NSR 43 IRQ_TYPE_LEVEL_HIGH>, 94 <ICU_GRP_NSR 47 IRQ_TYPE_LEVEL_HIGH>, 95 <ICU_GRP_NSR 51 IRQ_TYPE_LEVEL_HIGH>, 96 <ICU_GRP_NSR 55 IRQ_TYPE_LEVEL_HIGH>, 97 <ICU_GRP_NSR 59 IRQ_TYPE_LEVEL_HIGH>, 98 <ICU_GRP_NSR 63 IRQ_TYPE_LEVEL_HIGH>, 99 <ICU_GRP_NSR 67 IRQ_TYPE_LEVEL_HIGH>, 100 <ICU_GRP_NSR 71 IRQ_TYPE_LEVEL_HIGH>, 101 <ICU_GRP_NSR 129 IRQ_TYPE_LEVEL_HIGH>; 102 interrupt-names = "hif0", "hif1", "hif2", "hif3", "hif4", 103 "hif5", "hif6", "hif7", "hif8", "link"; 104 port-id = <0>; 105 gop-port-id = <0>; 106 }; 107 108 eth1: eth1 { 109 interrupts = <ICU_GRP_NSR 40 IRQ_TYPE_LEVEL_HIGH>, 110 <ICU_GRP_NSR 44 IRQ_TYPE_LEVEL_HIGH>, 111 <ICU_GRP_NSR 48 IRQ_TYPE_LEVEL_HIGH>, 112 <ICU_GRP_NSR 52 IRQ_TYPE_LEVEL_HIGH>, 113 <ICU_GRP_NSR 56 IRQ_TYPE_LEVEL_HIGH>, 114 <ICU_GRP_NSR 60 IRQ_TYPE_LEVEL_HIGH>, 115 <ICU_GRP_NSR 64 IRQ_TYPE_LEVEL_HIGH>, 116 <ICU_GRP_NSR 68 IRQ_TYPE_LEVEL_HIGH>, 117 <ICU_GRP_NSR 72 IRQ_TYPE_LEVEL_HIGH>, 118 <ICU_GRP_NSR 128 IRQ_TYPE_LEVEL_HIGH>; 119 interrupt-names = "hif0", "hif1", "hif2", "hif3", "hif4", 120 "hif5", "hif6", "hif7", "hif8", "link"; 121 port-id = <1>; 122 gop-port-id = <2>; 123 }; 124 125 eth2: eth2 { 126 interrupts = <ICU_GRP_NSR 41 IRQ_TYPE_LEVEL_HIGH>, 127 <ICU_GRP_NSR 45 IRQ_TYPE_LEVEL_HIGH>, 128 <ICU_GRP_NSR 49 IRQ_TYPE_LEVEL_HIGH>, 129 <ICU_GRP_NSR 53 IRQ_TYPE_LEVEL_HIGH>, 130 <ICU_GRP_NSR 57 IRQ_TYPE_LEVEL_HIGH>, 131 <ICU_GRP_NSR 61 IRQ_TYPE_LEVEL_HIGH>, 132 <ICU_GRP_NSR 65 IRQ_TYPE_LEVEL_HIGH>, 133 <ICU_GRP_NSR 69 IRQ_TYPE_LEVEL_HIGH>, 134 <ICU_GRP_NSR 73 IRQ_TYPE_LEVEL_HIGH>, 135 <ICU_GRP_NSR 127 IRQ_TYPE_LEVEL_HIGH>; 136 interrupt-names = "hif0", "hif1", "hif2", "hif3", "hif4", 137 "hif5", "hif6", "hif7", "hif8", "link"; 138 port-id = <2>; 139 gop-port-id = <3>; 140 }; 141};
