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 | |||
