This patch adds support for Broadcom's BCM53xx switch family, also known as RoboSwitch. Some of these switches are ubiquituous, found in home routers, Wi-Fi routers, DSL and cable modem gateways and other networking related products. This drivers adds the library driver (b53_common.c) as well as a few bus glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx). Basic operations are supported to bring the Layer 1/2 up and running, but not much more at this point, subsequent patches add the remaining features.

Examples:
|
|
|
|
Ethernet switch connected via MDIO to the host, CPU port wired to eth0:
|
|
|
|
eth0: ethernet@10001000 {
|
|
compatible = "brcm,unimac";
|
|
reg = <0x10001000 0x1000>;
|
|
|
|
fixed-link {
|
|
speed = <1000>;
|
|
duplex-full;
|
|
};
|
|
};
|
|
|
|
mdio0: mdio@10000000 {
|
|
compatible = "brcm,unimac-mdio";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
switch0: ethernet-switch@30 {
|
|
compatible = "brcm,bcm53125";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
