+Broadcom BCM63138 DSL System-on-a-Chip device tree bindings
+-----------------------------------------------------------
+
+Boards compatible with the BCM63138 DSL System-on-a-Chip should have the
+following properties:
+
+Required root node property:
+
+compatible: should be "brcm,bcm63138"
+
+An optional Boot lookup table Device Tree node is required for secondary CPU
+initialization as well as a 'resets' phandle to the correct PMB controller as
+defined in reset/brcm,bcm63138-pmb.txt for this secondary CPU, and an
+'enable-method' property.
+
+Required properties for the Boot lookup table node:
+- compatible: should be "brcm,bcm63138-bootlut"
+- reg: register base address and length for the Boot Lookup table
+
+Optional properties for the primary CPU node:
+- enable-method: should be "brcm,bcm63138"
+
+Optional properties for the secondary CPU node:
+- enable-method: should be "brcm,bcm63138"
+- resets: phandle to the relevant PMB controller, one integer indicating the internal
+  bus number, and a second integer indicating the address of the CPU in the PMB
+  internal bus number.
+
+Example:
+
+	cpus {
+		cpu@0 {
+			compatible = "arm,cortex-a9";
+			reg = <0>;
+			...
+			enable-method = "brcm,bcm63138";
+		};
+
+		cpu@1 {
+			compatible = "arm,cortex-a9";
+			reg = <1>;
+			...
+			enable-method = "brcm,bcm63138";
+			resets = <&pmb0 4 1>;
+		};
+	};
+
+	bootlut: bootlut@8000 {
+		compatible = "brcm,bcm63138-bootlut";
+		reg = <0x8000 0x50>;
+	};
+
+=======
+reboot
+------
+Two nodes are required for software reboot: a timer node and a syscon-reboot node.
+
+Timer node:
+
+- compatible: Must be "brcm,bcm6328-timer", "syscon"
+- reg: Register base address and length
+
+Syscon reboot node:
+
+See Documentation/devicetree/bindings/power/reset/syscon-reboot.yaml for the
+detailed list of properties, the two values defined below are specific to the
+BCM6328-style timer:
+
+- offset: Should be 0x34 to denote the offset of the TIMER_WD_TIMER_RESET register
+  from the beginning of the TIMER block
+- mask: Should be 1 for the SoftRst bit.
+
+Example:
+
+	timer: timer@80 {
+		compatible = "brcm,bcm6328-timer", "syscon";
+		reg = <0x80 0x3c>;
+	};
+
+	reboot {
+		compatible = "syscon-reboot";
+		regmap = <&timer>;
+		offset = <0x34>;
+		mask = <0x1>;
+	};

+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>-cpu-biu-ctrl",
+		  "brcm,brcmstb-cpu-biu-ctrl",
+		  "syscon"
+    - compatible: "brcm,bcm<chip_id>-hif-continuation", "syscon"
+
+cpu-biu-ctrl node
+-------------------
+SoCs with Broadcom Brahma15 ARM-based and Brahma53 ARM64-based CPUs have a
+specific Bus Interface Unit (BIU) block which controls and interfaces the CPU
+complex to the different Memory Controller Ports (MCP), one per memory
+controller (MEMC). This BIU block offers a feature called Write Pairing which
+consists in collapsing two adjacent cache lines into a single (bursted) write
+transaction towards the memory controller (MEMC) to maximize write bandwidth.
+
+Required properties:
+
+    - compatible: must be "brcm,bcm7445-cpu-biu-ctrl", "brcm,brcmstb-cpu-biu-ctrl", "syscon"
+
+Optional properties:
+
+    - brcm,write-pairing:
+	Boolean property, which when present indicates that the chip
+	supports write-pairing.
+
+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-cpu-biu-ctrl", "brcm,brcmstb-cpu-biu-ctrl", "syscon";
+            reg = <0x3e2400 0x5b4>;
+            brcm,write-pairing;
+        };
+
+        hif_continuation: syscon@452000 {
+            compatible = "brcm,bcm7445-hif-continuation", "syscon";
+            reg = <0x452000 0x100>;
+        };
+    };
+
+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" for 40nm/28nm chips with
+        the new SYS_CTRL interface, or "brcm,bcm7038-reboot" for 65nm
+        chips with the old SUN_TOP_CTRL interface.
+
+    - 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>;
+    };
+
+
+
+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:
+- compatible     : should contain "brcm,brcmstb-aon-ctrl"
+- reg            : the register start and length for the AON CTRL block
+
+Example:
+
+aon-ctrl@410000 {
+	compatible = "brcm,brcmstb-aon-ctrl";
+	reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY). See
+the example device tree snippet below.
+
+== MEMC (MEMory Controller)
+
+Represents a single memory controller instance.
+
+Required properties:
+- compatible     : should contain "brcm,brcmstb-memc" and "simple-bus"
+
+Should contain subnodes for any of the following relevant hardware resources:
+
+== DDR PHY control
+
+Control registers for this memory controller's DDR PHY.
+
+Required properties:
+- compatible     : should contain one of these
+	"brcm,brcmstb-ddr-phy-v71.1"
+	"brcm,brcmstb-ddr-phy-v72.0"
+	"brcm,brcmstb-ddr-phy-v225.1"
+	"brcm,brcmstb-ddr-phy-v240.1"
+	"brcm,brcmstb-ddr-phy-v240.2"
+
+- reg            : the DDR PHY register range
+
+== DDR SHIMPHY
+
+Control registers for this memory controller's DDR SHIMPHY.
+
+Required properties:
+- compatible     : should contain "brcm,brcmstb-ddr-shimphy-v1.0"
+- reg            : the DDR SHIMPHY register range
+
+== MEMC DDR control
+
+Sequencer DRAM parameters and control registers. Used for Self-Refresh
+Power-Down (SRPD), among other things.
+
+See Documentation/devicetree/bindings/memory-controllers/brcm,brcmstb-memc-ddr.yaml for a
+full list of supported compatible strings and properties.
+
+Example:
+
+memory_controllers {
+	ranges;
+	compatible = "simple-bus";
+
+	memc@0 {
+		compatible = "brcm,brcmstb-memc", "simple-bus";
+		ranges;
+
+		ddr-phy@f1106000 {
+			compatible = "brcm,brcmstb-ddr-phy-v240.1";
+			reg = <0xf1106000 0x21c>;
+		};
+
+		shimphy@f1108000 {
+			compatible = "brcm,brcmstb-ddr-shimphy-v1.0";
+			reg = <0xf1108000 0xe4>;
+		};
+
+		memc-ddr@f1102000 {
+			reg = <0xf1102000 0x800>;
+			compatible = "brcm,brcmstb-memc-ddr";
+		};
+	};
+
+	memc@1 {
+		compatible = "brcm,brcmstb-memc", "simple-bus";
+		ranges;
+
+		ddr-phy@f1186000 {
+			compatible = "brcm,brcmstb-ddr-phy-v240.1";
+			reg = <0xf1186000 0x21c>;
+		};
+
+		shimphy@f1188000 {
+			compatible = "brcm,brcmstb-ddr-shimphy-v1.0";
+			reg = <0xf1188000 0xe4>;
+		};
+
+		memc-ddr@f1182000 {
+			reg = <0xf1182000 0x800>;
+			compatible = "brcm,brcmstb-memc-ddr";
+		};
+	};
+
+	memc@2 {
+		compatible = "brcm,brcmstb-memc", "simple-bus";
+		ranges;
+
+		ddr-phy@f1206000 {
+			compatible = "brcm,brcmstb-ddr-phy-v240.1";
+			reg = <0xf1206000 0x21c>;
+		};
+
+		shimphy@f1208000 {
+			compatible = "brcm,brcmstb-ddr-shimphy-v1.0";
+			reg = <0xf1208000 0xe4>;
+		};
+
+		memc-ddr@f1202000 {
+			reg = <0xf1202000 0x800>;
+			compatible = "brcm,brcmstb-memc-ddr";
