+Broadcom STB platforms Device Tree Bindings
+-------------------------------------------
+Boards with Broadcom Brahma15-based BCM7xxx SOC shall have the following
+properties.
+
+Required root node properties:
+    - compatible = "brcm,brcmstb";
+
+Further, the following platform nodes shall be defined:
+
+    - sun-top-ctrl
+    - cpu-biu-ctrl
+    - hif-continuation
+
+sun-top-ctrl
+------------
+This node describes the register block which is used for generic reset control.
+
+    - compatible: "brcm,brcmstb-sun-top-ctrl"
+    - properties:
+        o reg = <base_of_sun_top_ctrl_regs length>;
+        o reset-source-enable-reg = <offset_from_base>;
+        o sw-master-reset-reg = <offset_from_base>;
+
+cpu-biu-ctrl
+------------
+This node describes the register block used for configuring the CPU complex.
+
+    - compatible: "brcm,brcmstb-cpu-biu-ctrl"
+    - properties:
+        o reg = <base_of_cpu_biu_ctrl_regs length>;
+        o cpu-reset-config-reg = <offset_from_base>;
+        o cpu0-pwr-zone-ctrl-reg = <offset_from_base>;
+
+hif-continuation
+----------------
+This node describes the registers for setting the starting PC for each CPU core.
+
+    - compatible: "brcm,brcmstb-hif-continuation"
+    - properties:
+        o reg = <base_of_hif_continuation_regs length>;
+        o stb-boot-hi-addr0-reg = <offset_from_base>;
+
+example:
+
+/ {
+	model = "Broadcom STB";
+	compatible =  "brcm,brcmstb";
+
+	/* snip */
+
+	sun-top-ctrl at f0404000 {
+		compatible = "brcm,brcmstb-sun-top-ctrl";
+		reg = <0xf0404000 0x51c>;
+		reset-source-enable-reg = <0x304>;
+		sw-master-reset-reg = <0x308>;
+	};
+
+	cpu-biu-ctrl at f0442400 {
+		compatible = "brcm,brcmstb-cpu-biu-ctrl";
+		reg = <0xf0442400 0x5b4>;
+		cpu-reset-config-reg = <0x178>;
+		cpu0-pwr-zone-ctrl-reg = <0x88>;
+	};
+
+	hif-continuation at f0452000 {
+		compatible = "brcm,brcmstb-hif-continuation";
+		reg = <0xf0452000 0x100>;
+	};
+
+	/* snip */
+};
