+Broadcom STB SW_INIT-style reset controller
+===========================================
+
+Broadcom STB SoCs have a SW_INIT-style reset controller with separate
+SET/CLEAR/STATUS registers and possibly multiple banks, each of 32 bit
+reset lines.
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: should be brcm,brcmstb-reset
+- reg: register base and length
+- #reset-cells: must be set to 1
+
+Example:
+
+ reset: reset-controller@8404318 {
+ compatible = "brcm,brcmstb-reset";
+ reg = <0x8404318 0x30>;
+ #reset-cells = <1>;
+ };
+
+ ðernet_switch {
+ resets = <&reset>;
+ reset-names = "switch";
+ };
