+  The compatible property should follow this format:
+
+  compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform";
+
+  <targettype> represents the board/device and comes from the `target-type`
+  property of the root node of the Apple Device Tree, lowercased. It can be
+  queried on macOS using the following command:
+
+  $ ioreg -d2 -l | grep target-type
+
+  <socid> is the lowercased SoC ID. Apple uses at least *five* different
+  names for their SoCs:
+
+  - Marketing name ("M1")
+  - Internal name ("H13G")
+  - Codename ("Tonga")
+  - SoC ID ("T8103")
+  - Package/IC part number ("APL1102")
+
+  Devicetrees should use the lowercased SoC ID, to avoid confusion if
+  multiple SoCs share the same marketing name. This can be obtained from
+  the `compatible` property of the arm-io node of the Apple Device Tree,
+  which can be queried as follows on macOS:
+
+  $ ioreg -n arm-io | grep compatible

+description: >
+  ARM multi-cluster systems maintain intra-cluster coherency through a cache
+  coherent interconnect (CCI) that is capable of monitoring bus transactions
+  and manage coherency, TLB invalidations and memory barriers.
+
+  It allows snooping and distributed virtual memory message broadcast across
+  clusters, through memory mapped interface, with a global control register
+  space and multiple sets of interface control registers, one per slave
+  interface.

+description: |
+  CoreSight components are compliant with the ARM CoreSight architecture
+  specification and can be connected in various topologies to suit a particular
+  SoCs tracing needs. These trace components can generally be classified as
+  sinks, links and sources. Trace data produced by one or more sources flows
+  through the intermediate links connecting the source to the currently selected
+  sink.
+
+  The CoreSight Address Translation Unit (CATU) translates addresses between an
+  AXI master and system memory. The CATU is normally used along with the TMC to
+  implement scattering of virtual trace buffers in physical memory. The CATU
+  translates contiguous Virtual Addresses (VAs) from an AXI master into
+  non-contiguous Physical Addresses (PAs) that are intended for system memory.

+title: ARM Coresight Cross Trigger Interface (CTI) device.
+
+description: |
+  The CoreSight Embedded Cross Trigger (ECT) consists of CTI devices connected
+  to one or more CoreSight components and/or a CPU, with CTIs interconnected in
+  a star topology via the Cross Trigger Matrix (CTM), which is not programmable.
+  The ECT components are not part of the trace generation data path and are thus
+  not part of the CoreSight graph.
+
+  The CTI component properties define the connections between the individual
+  CTI and the components it is directly connected to, consisting of input and
+  output hardware trigger signals. CTIs can have a maximum number of input and
+  output hardware trigger signals (8 each for v1 CTI, 32 each for v2 CTI). The
+  number is defined at design time, the maximum of each defined in the DEVID
+  register.
+
+  CTIs are interconnected in a star topology via the CTM, using a number of
+  programmable channels, usually 4, but again implementation defined and
+  described in the DEVID register. The star topology is not required to be
+  described in the bindings as the actual connections are software
+  programmable.
+
+  In general the connections between CTI and components via the trigger signals
+  are implementation defined, except when the CTI is connected to an ARM v8
+  architecture core and optional ETM.
+
+  In this case the ARM v8 architecture defines the required signal connections
+  between CTI and the CPU core and ETM if present. In the case of a v8
+  architecturally connected CTI an additional compatible string is used to
+  indicate this feature (arm,coresight-cti-v8-arch).
+
+  When CTI trigger connection information is unavailable then a minimal driver
+  binding can be declared with no explicit trigger signals. This will result
+  the driver detecting the maximum available triggers and channels from the
+  DEVID register and make them all available for use as a single default
+  connection. Any user / client application will require additional information
+  on the connections between the CTI and other components for correct operation.
+  This information might be found by enabling the Integration Test registers in
+  the driver (set CONFIG_CORESIGHT_CTI_INTEGRATION_TEST in Kernel
+  configuration). These registers may be used to explore the trigger connections
+  between CTI and other CoreSight components.
+
+  Certain triggers between CoreSight devices and the CTI have specific types
+  and usages. These can be defined along with the signal indexes with the
+  constants defined in <dt-bindings/arm/coresight-cti-dt.h>
+
+  For example a CTI connected to a core will usually have a DBGREQ signal. This
+  is defined in the binding as type PE_EDBGREQ. These types will appear in an
+  optional array alongside the signal indexes. Omitting types will default all
+  signals to GEN_IO.
+
+  Note that some hardware trigger signals can be connected to non-CoreSight
+  components (e.g. UART etc) depending on hardware implementation.

+
+description: |
+  CoreSight components are compliant with the ARM CoreSight architecture
+  specification and can be connected in various topologies to suit a particular
+  SoCs tracing needs. These trace components can generally be classified as
+  sinks, links and sources. Trace data produced by one or more sources flows
+  through the intermediate links connecting the source to the currently selected
+  sink.
+
+  The Coresight dummy sink component is for the specific coresight sink devices
+  kernel don't have permission to access or configure, e.g., CoreSight EUD on
+  Qualcomm platforms. It is a mini-USB hub implemented to support the USB-based
+  debug and trace capabilities. For this device, a dummy driver is needed to
+  register it as Coresight sink device in kernel side, so that path can be
+  created in the driver. Then the trace flow would be transferred to EUD via
+  coresight link of AP processor. It provides Coresight API for operations on
+  dummy source devices, such as enabling and disabling them. It also provides
+  the Coresight dummy source paths for debugging.
+
+  The primary use case of the coresight dummy sink is to build path in kernel
+  side for dummy sink component.

+  CoreSight components are compliant with the ARM CoreSight architecture

+description: |
+  Arm Embedded Trace Extension(ETE) is a per CPU trace component that
+  allows tracing the CPU execution. It overlaps with the CoreSight ETMv4
+  architecture and has extended support for future architecture changes.
+  The trace generated by the ETE could be stored via legacy CoreSight
+  components (e.g, TMC-ETR) or other means (e.g, using a per CPU buffer
+  Arm Trace Buffer Extension (TRBE)). Since the ETE can be connected to
+  legacy CoreSight components, a node must be listed per instance, along
+  with any optional connection graph as per the coresight bindings.

+description: |+
+  ARM's Versatile Express platform were built as reference designs for exploring
+  multicore Cortex-A class systems. The Versatile Express family contains both
+  32 bit (Aarch32) and 64 bit (Aarch64) systems.
+
+  The board consist of a motherboard and one or more daughterboards (tiles). The
+  motherboard provides a set of peripherals. Processor and RAM "live" on the
+  tiles.
+
+  The motherboard and each core tile should be described by a separate Device
+  Tree source file, with the tile's description including the motherboard file
+  using an include directive. As the motherboard can be initialized in one of
+  two different configurations ("memory maps"), care must be taken to include
+  the correct one.
+
+  When a new generation of boards were introduced under the name "Juno", these
+  shared to many common characteristics with the Versatile Express that the
+  "arm,vexpress" compatible was retained in the root node, and these are
+  included in this binding schema as well.
+
+  The root node indicates the CPU SoC on the core tile, and this
+  is a daughterboard to the main motherboard. The name used in the compatible
+  string shall match the name given in the core tile's technical reference
+  manual, followed by "arm,vexpress" as an additional compatible value. If
+  further subvariants are released of the core tile, even more fine-granular
+  compatible strings with up to three compatible strings are used.

+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";

+		shimphy@f1108000 {
+			compatible = "brcm,brcmstb-ddr-shimphy-v1.0";
+			reg = <0xf1108000 0xe4>;
+		};
+
+		memc-ddr@f1102000 {
+			reg = <0xf1102000 0x800>;

+	};
+
+	memc@2 {
+		compatible = "brcm,brcmstb-memc", "simple-bus";
+		ranges;
+
+		ddr-phy@f1206000 {

+Secondary CPU enable-method "al,alpine-smp" binding
+========================================================
+
+This document describes the "al,alpine-smp" method for
+enabling secondary CPUs. To apply to all CPUs, a single
+"al,alpine-smp" enable method should be defined in the
+"cpus" node.
+
+Enable method name:	"al,alpine-smp"
+Compatible machines:	"al,alpine"
+Compatible CPUs:	"arm,cortex-a15"
+Related properties:	(none)
+
+Note:
+This enable method requires valid nodes compatible with
+"al,alpine-cpu-resume" and "al,alpine-nb-service".
+
+
+* Alpine CPU resume registers
+
+The CPU resume register are used to define required resume address after
+reset.
+
+Properties:
+- compatible : Should contain "al,alpine-cpu-resume".
+- reg : Offset and length of the register set for the device
+
+
+Example:
+
+cpus {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	enable-method = "al,alpine-smp";
+
+	cpu@0 {
+		compatible = "arm,cortex-a15";
+		device_type = "cpu";
+		reg = <0>;
+	};

+description: |+
+  The device tree allows to describe the layout of CPUs in a system through the
+  "cpus" node, which in turn contains a number of subnodes (ie "cpu") defining
+  properties for every cpu.
+
+  Bindings for CPU nodes follow the Devicetree Specification, available from:
+
+  https://www.devicetree.org/specifications/
+
+  with updates for 32-bit and 64-bit ARM systems provided in this document.
+
+  ================================
+  Convention used in this document
+  ================================
+
+  This document follows the conventions described in the Devicetree
+  Specification, with the addition:
+
+  - square brackets define bitfields, eg reg[7:0] value of the bitfield in
+    the reg property contained in bits 7 down to 0
+
+  =====================================
+  cpus and cpu node bindings definition
+  =====================================
+
+  The ARM architecture, in accordance with the Devicetree Specification,
+  requires the cpus and cpu nodes to be present and contain the properties
+  described below.
+
+properties:
+  reg:
+    maxItems: 1
+    description: >
+      Usage and definition depend on ARM architecture version and configuration:
+
+      On uniprocessor ARM architectures previous to v7 this property is required
+      and must be set to 0.
+
+      On ARM 11 MPcore based systems this property is required and matches the
+      CPUID[11:0] register bits.
+
+        Bits [11:0] in the reg cell must be set to bits [11:0] in CPU ID register.
+
+        All other bits in the reg cell must be set to 0.
+
+      On 32-bit ARM v7 or later systems this property is required and matches
+      the CPU MPIDR[23:0] register bits.
+
+        Bits [23:0] in the reg cell must be set to bits [23:0] in MPIDR.
+
+        All other bits in the reg cell must be set to 0.
+
+      On ARM v8 64-bit systems this property is required and matches the
+      MPIDR_EL1 register affinity bits.
+
+        * If cpus node's #address-cells property is set to 2
+
+          The first reg cell bits [7:0] must be set to bits [39:32] of
+          MPIDR_EL1.
+
+          The second reg cell bits [23:0] must be set to bits [23:0] of
+          MPIDR_EL1.
+
+        * If cpus node's #address-cells property is set to 1
+
+          The reg cell bits [23:0] must be set to bits [23:0] of MPIDR_EL1.
+
+      All other bits in the reg cells must be set to 0.

+* Software Delegated Exception Interface (SDEI)
+
+Firmware implementing the SDEI functions described in ARM document number
+ARM DEN 0054A ("Software Delegated Exception Interface") can be used by
+Linux to receive notification of events such as those generated by
+firmware-first error handling, or from an IRQ that has been promoted to
+a firmware-assisted NMI.
+
+The interface provides a number of API functions for registering callbacks
+and enabling/disabling events. Functions are invoked by trapping to the
+privilege level of the SDEI firmware (specified as part of the binding
+below) and passing arguments in a manner specified by the "SMC Calling
+Convention (ARM DEN 0028B):
+
+	 r0		=> 32-bit Function ID / return value
+	{r1 - r3}	=> Parameters
+
+Note that the immediate field of the trapping instruction must be set
+to #0.
+
+The SDEI_EVENT_REGISTER function registers a callback in the kernel
+text to handle the specified event number.
+
+The sdei node should be a child node of '/firmware' and have required
+properties:
+
+ - compatible    : should contain:
+	* "arm,sdei-1.0" : For implementations complying to SDEI version 1.x.
+
+ - method        : The method of calling the SDEI firmware. Permitted

+	          binding.
+	* "hvc" : HVC #0, with the register assignments specified in this
+	          binding.

+	firmware {
+		sdei {
+			compatible	= "arm,sdei-1.0";
+			method		= "smc";

+  produced by Storlink Semiconductor around 2005. The company was renamed
+  later renamed Storm Semiconductor. The chip product name is Storlink SL3516.
+  It was derived from earlier products from Storm named SL3316 (Centroid) and
+  SL3512 (Bulverde).
+
+  Storm Semiconductor was acquired by Cortina Systems in 2008 and the SoC was
+  produced and used for NAS and similar usecases. In 2014 Cortina Systems was
+  in turn acquired by Inphi, who seem to have discontinued this product family.
+
+  Many of the IP blocks used in the SoC comes from Faraday Technology.

+description: |
+  Hisilicon HiP06 SoCs implement a Low Pin Count (LPC) controller, which
+  provides I/O access to some legacy ISA devices.
+  HiP06 is based on arm64 architecture where there is no I/O space. So, the
+  I/O ports here are not CPU addresses, and there is no 'ranges' property in
+  LPC device node.
+
+properties:
+  $nodename:
+    pattern: '^isa@[0-9a-f]+$'
+    description: |
+      The node name before '@' must be "isa" to represent the binding stick
+      to the ISA/EISA binding specification.
