Kurt Kanzenbach 61d0301e6c dt-bindings: net: dsa: b53: Add missing size and address cells to example
Add the missing size and address cells to the b53 example. Otherwise, it may not
compile or issue warnings if directly copied into a device tree.

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_p1"
"link_state_p2"
"link_state_p3"
"link_state_p4"
"link_state_p5"

"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>;
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>;
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>;
duplex-full;
};
phy-mode = "rgmii-txid";
};
port8@8 {
reg = <8>;
label = "cpu";
fixed-link {
speed = <1000>;
duplex-full;
};
phy-mode = "rgmii-txid";
ethernet = <&eth0>;
};
};
};
};
