|
|
pairs of register addresses and lengths
|
|
- interrupts: interrupts for the devices, must be two interrupts
|
|
- #address-cells: must be 1, see dsa/dsa.txt

|
|
|
|
Deprecated binding required properties:
|
|
|
|
- dsa,mii-bus: phandle to the MDIO bus controller, see dsa/dsa.txt
|
|
- dsa,ethernet: phandle to the CPU network interface controller, see dsa/dsa.txt
|
|
- #address-cells: must be 2, see dsa/dsa.txt
|
|
|
|
Subnodes:
|
|
|
|
The integrated switch subnode should be specified according to the binding
|
|
described in dsa/dsa.txt.
|
|
|
|
Optional properties:
|
|
|
|
- reg-names: litteral names for the device base register addresses, when present
|
|
must be: "core", "reg", "intrl2_0", "intrl2_1", "fcb", "acb"
|
|
|
|
- interrupt-names: litternal names for the device interrupt lines, when present
|
|
must be: "switch_0" and "switch_1"
|
|
|
|
- brcm,num-gphy: specify the maximum number of integrated gigabit PHYs in the
|
|
switch
|
|
|
|
- brcm,num-rgmii-ports: specify the maximum number of RGMII interfaces supported
|
|
by the switch
|
|
|
|
- brcm,fcb-pause-override: boolean property, if present indicates that the switch
|
|
supports Failover Control Block pause override capability
|
|
|
|
- brcm,acb-packets-inflight: boolean property, if present indicates that the switch
|
|
Admission Control Block supports reporting the number of packets in-flight in a
|
|

|
|
Port subnodes:
|
|
|
|
Optional properties:
|
|
|
|
- brcm,use-bcm-hdr: boolean property, if present, indicates that the switch
|
|
port has Broadcom tags enabled (per-packet metadata)
|
|
|
|
