dt-bindings: brcm: rationalize Broadcom documentation naming
This patchset attempts to standardize the naming of dt-bindings documents based on the Broadcom vendor prefix of brcm. Although there are no guidelines currently present for how to name the dt-bindings document the "vendor,binding.txt" style is in use by some of the other vendors.

+* Broadcom Starfighter 2 integrated swich
+
+Required properties:
+
+- compatible: should be "brcm,bcm7445-switch-v4.0"
+- reg: addresses and length of the register sets for the device, must be 6
+ pairs of register addresses and lengths
+- interrupts: interrupts for the devices, must be two interrupts
+- 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
+- #size-cells: must be 0
+- #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
+ switch queue
+
