Broadcom BCM53xx Ethernet switches
==================================
Required properties:
- compatible: For external switch chips, compatible string must be exactly one
of: "brcm,bcm5325"
"brcm,bcm53115"
"brcm,bcm53125"
"brcm,bcm53128"
"brcm,bcm5365"
"brcm,bcm5395"
"brcm,bcm5389"
"brcm,bcm5397"
"brcm,bcm5398"
For the BCM11360 SoC, must be:
"brcm,bcm11360-srab" and the mandatory "brcm,cygnus-srab" string
For the BCM5310x SoCs with an integrated switch, must be one of:
"brcm,bcm53010-srab"
"brcm,bcm53011-srab"
"brcm,bcm53012-srab"
"brcm,bcm53018-srab"
"brcm,bcm53019-srab" and the mandatory "brcm,bcm5301x-srab" string
For the BCM5831X/BCM1140x SoCs with an integrated switch, must be one of:
"brcm,bcm11404-srab"
"brcm,bcm11407-srab"
"brcm,bcm11409-srab"
"brcm,bcm58310-srab"
"brcm,bcm58311-srab"
"brcm,bcm58313-srab" and the mandatory "brcm,omega-srab" string
For the BCM585xx/586XX/88312 SoCs with an integrated switch, must be one of:
"brcm,bcm58522-srab"
"brcm,bcm58523-srab"
"brcm,bcm58525-srab"
"brcm,bcm58622-srab"
"brcm,bcm58623-srab"
"brcm,bcm58625-srab"
"brcm,bcm88312-srab" and the mandatory "brcm,nsp-srab string
For the BCM63xx/33xx SoCs with an integrated switch, must be one of:
"brcm,bcm3384-switch"
"brcm,bcm6328-switch"
"brcm,bcm6368-switch" and the mandatory "brcm,bcm63xx-switch"
Required properties for BCM585xx/586xx/88312 SoCs:
- reg: a total of 3 register base addresses, the first one must be the
Switch Register Access block base, the second is the port 5/4 mux
configuration register and the third one is the SGMII configuration
and status register base address.
- interrupts: a total of 13 interrupts must be specified, in the following
order: port 0-5, 7-8 link status change, then the integrated PHY interrupt,
then the timestamping interrupt and the sleep timer interrupts for ports
5,7,8.
Optional properties for BCM585xx/586xx/88312 SoCs:
- reg-names: a total of 3 names matching the 3 base register address, must
be in the following order:
"srab"
"mux_config"
"sgmii_config"
- interrupt-names: a total of 13 names matching the 13 interrupts specified
must be in the following order:
"link_state_p0"
"link_state_p1"
"link_state_p2"
"link_state_p3"
"link_state_p4"
"link_state_p5"
"link_state_p7"
"link_state_p8"
"phy"
"ts"
"imp_sleep_timer_p5"
"imp_sleep_timer_p7"
"imp_sleep_timer_p8"
See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional
required and optional properties.
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>;
full-duplex;
};
};
mdio0: mdio@10000000 {
compatible = "brcm,unimac-mdio";
#address-cells = <1>;
#size-cells = <0>;
switch0: ethernet-switch@1e {
compatible = "brcm,bcm53125";
reg = <30>;
#address-cells = <1>;
#size-cells = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port0@0 {
reg = <0>;
label = "lan1";
};
port1@1 {
reg = <1>;
label = "lan2";
};
port5@5 {
reg = <5>;
label = "cable-modem";
fixed-link {
speed = <1000>;
full-duplex;
};
phy-mode = "rgmii-txid";
};
port8@8 {
reg = <8>;
label = "cpu";
fixed-link {
speed = <1000>;
full-duplex;
};
phy-mode = "rgmii-txid";
ethernet = <&eth0>;
};
};
};
};
