1Microsemi Ocelot network Switch 2=============================== 3 4The Microsemi Ocelot network switch can be found on Microsemi SoCs (VSC7513, 5VSC7514) 6 7Required properties: 8- compatible: Should be "mscc,vsc7514-switch" 9- reg: Must contain an (offset, length) pair of the register set for each 10 entry in reg-names. 11- reg-names: Must include the following entries: 12 - "sys" 13 - "rew" 14 - "qs" 15 - "ptp" (optional due to backward compatibility) 16 - "qsys" 17 - "ana" 18 - "portX" with X from 0 to the number of last port index available on that 19 switch 20- interrupts: Should contain the switch interrupts for frame extraction, 21 frame injection and PTP ready. 22- interrupt-names: should contain the interrupt names: "xtr", "inj". Can contain 23 "ptp_rdy" which is optional due to backward compatibility. 24- ethernet-ports: A container for child nodes representing switch ports. 25 26The ethernet-ports container has the following properties 27 28Required properties: 29 30- #address-cells: Must be 1 31- #size-cells: Must be 0 32 33Each port node must have the following mandatory properties: 34- reg: Describes the port address in the switch 35 36Port nodes may also contain the following optional standardised 37properties, described in binding documents: 38 39- phy-handle: Phandle to a PHY on an MDIO bus. See 40 Documentation/devicetree/bindings/net/ethernet.txt for details. 41 42Example: 43 44 switch@1010000 { 45 compatible = "mscc,vsc7514-switch"; 46 reg = <0x1010000 0x10000>, 47 <0x1030000 0x10000>, 48 <0x1080000 0x100>, 49 <0x10e0000 0x10000>, 50 <0x11e0000 0x100>, 51 <0x11f0000 0x100>, 52 <0x1200000 0x100>, 53 <0x1210000 0x100>, 54 <0x1220000 0x100>, 55 <0x1230000 0x100>, 56 <0x1240000 0x100>, 57 <0x1250000 0x100>, 58 <0x1260000 0x100>, 59 <0x1270000 0x100>, 60 <0x1280000 0x100>, 61 <0x1800000 0x80000>, 62 <0x1880000 0x10000>; 63 reg-names = "sys", "rew", "qs", "ptp", "port0", "port1", 64 "port2", "port3", "port4", "port5", "port6", 65 "port7", "port8", "port9", "port10", "qsys", 66 "ana"; 67 interrupts = <18 21 22>; 68 interrupt-names = "ptp_rdy", "xtr", "inj"; 69 70 ethernet-ports { 71 #address-cells = <1>; 72 #size-cells = <0>; 73 74 port0: port@0 { 75 reg = <0>; 76 phy-handle = <&phy0>; 77 }; 78 port1: port@1 { 79 reg = <1>; 80 phy-handle = <&phy1>; 81 }; 82 }; 83 }; 84
