+Broadcom Kona Family CPU Enable Method
+--------------------------------------
+This binding defines the enable method used for starting secondary
+CPUs in the following Broadcom SoCs:
+  BCM11130, BCM11140, BCM11351, BCM28145, BCM28155, BCM21664
+
+The enable method is specified by defining the following required
+properties in the "cpus" device tree node:
+  - enable-method = "brcm,bcm11351-cpu-method";
+  - secondary-boot-reg = <...>;
+
+The secondary-boot-reg property is a u32 value that specifies the
+physical address of the register used to request the ROM holding pen
+code release a secondary CPU.  The value written to the register is
+formed by encoding the target CPU id into the low bits of the
+physical start address it should jump to.
+
+Example:
+	cpus {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		enable-method = "brcm,bcm11351-cpu-method";
+		secondary-boot-reg = <0x3500417c>;
+
+		cpu0: cpu@0 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a9";
+			reg = <0>;
+		};
+
+		cpu1: cpu@1 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a9";
+			reg = <1>;
+		};
+	};

+ARM Broadcom STB platforms Device Tree Bindings
+-----------------------------------------------
+Boards with Broadcom Brahma15 ARM-based BCMxxxx (generally BCM7xxx variants)
+SoC shall have the following DT organization:
+
+Required root node properties:
+    - compatible: "brcm,bcm<chip_id>", "brcm,brcmstb"
+
+example:
+/ {
+    #address-cells = <2>;
+    #size-cells = <2>;
+    model = "Broadcom STB (bcm7445)";
+    compatible = "brcm,bcm7445", "brcm,brcmstb";
+
+Further, syscon nodes that map platform-specific registers used for general
+system control is required:
+
+    - compatible: "brcm,bcm<chip_id>-sun-top-ctrl", "syscon"
+    - compatible: "brcm,bcm<chip_id>-hif-cpubiuctrl", "syscon"
+    - compatible: "brcm,bcm<chip_id>-hif-continuation", "syscon"
+
+example:
+    rdb {
+        #address-cells = <1>;
+        #size-cells = <1>;
+        compatible = "simple-bus";
+        ranges = <0 0x00 0xf0000000 0x1000000>;
+
+        sun_top_ctrl: syscon@404000 {
+            compatible = "brcm,bcm7445-sun-top-ctrl", "syscon";
+            reg = <0x404000 0x51c>;
+        };
+
+        hif_cpubiuctrl: syscon@3e2400 {
+            compatible = "brcm,bcm7445-hif-cpubiuctrl", "syscon";
+            reg = <0x3e2400 0x5b4>;

+            reg = <0x452000 0x100>;
+        };
+    };
+
+Lastly, nodes that allow for support of SMP initialization and reboot are
+required:
+
+smpboot
+-------
+Required properties:
+
+    - compatible
+        The string "brcm,brcmstb-smpboot".
+
+    - syscon-cpu
+        A phandle / integer array property which lets the BSP know the location
+        of certain CPU power-on registers.
+
+        The layout of the property is as follows:
+            o a phandle to the "hif_cpubiuctrl" syscon node
+            o offset to the base CPU power zone register
+            o offset to the base CPU reset register
+
+    - syscon-cont
+        A phandle pointing to the syscon node which describes the CPU boot
+        continuation registers.
+            o a phandle to the "hif_continuation" syscon node
+
+example:
+    smpboot {
+        compatible = "brcm,brcmstb-smpboot";
+        syscon-cpu = <&hif_cpubiuctrl 0x88 0x178>;
+        syscon-cont = <&hif_continuation>;
+    };
+
+reboot
+-------
+Required properties
+
+    - compatible
+        The string property "brcm,brcmstb-reboot".
+
+    - syscon
+        A phandle / integer array that points to the syscon node which describes
+        the general system reset registers.
+            o a phandle to "sun_top_ctrl"
+            o offset to the "reset source enable" register
+            o offset to the "software master reset" register
+
+example:
+    reboot {
+        compatible = "brcm,brcmstb-reboot";
+        syscon = <&sun_top_ctrl 0x304 0x308>;
+    };
