1 | * Broadcom Starfighter 2 integrated swich |
| 2 | ||
| 3 | Required properties: | |
| 4 | ||
| 5 | - compatible: should be "brcm,bcm7445-switch-v4.0" | |
| 6 | - reg: addresses and length of the register sets for the device, must be 6 | |
| 7 | pairs of register addresses and lengths | |
| 8 | - interrupts: interrupts for the devices, must be two interrupts | |
| 9 | - dsa,mii-bus: phandle to the MDIO bus controller, see dsa/dsa.txt | |
| 10 | - dsa,ethernet: phandle to the CPU network interface controller, see dsa/dsa.txt | |
| 11 | - #size-cells: must be 0 | |
| 12 | - #address-cells: must be 2, see dsa/dsa.txt | |
| 13 | ||
| 14 | Subnodes: | |
| 15 | ||
| 16 | The integrated switch subnode should be specified according to the binding | |
| 17 | described in dsa/dsa.txt. | |
| 18 | ||
| 19 | Optional properties: | |
| 20 | ||
| 21 | - reg-names: litteral names for the device base register addresses, when present | |
| 22 | must be: "core", "reg", "intrl2_0", "intrl2_1", "fcb", "acb" | |
| 23 | ||
| 24 | - interrupt-names: litternal names for the device interrupt lines, when present | |
| 25 | must be: "switch_0" and "switch_1" | |
| 26 | ||
| 27 | - brcm,num-gphy: specify the maximum number of integrated gigabit PHYs in the | |
| 28 | switch | |
| 29 | ||
| 30 | - brcm,num-rgmii-ports: specify the maximum number of RGMII interfaces supported | |
| 31 | by the switch | |
| 32 | ||
| 33 | - brcm,fcb-pause-override: boolean property, if present indicates that the switch | |
| 34 | supports Failover Control Block pause override capability | |
| 35 | ||
| 36 | - brcm,acb-packets-inflight: boolean property, if present indicates that the switch | |
| 37 | Admission Control Block supports reporting the number of packets in-flight in a | |
| 38 | switch queue | |
| 39 | ||
