Merge tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: "DeviceTree updates for 3.13. This is a bit larger pull request than usual for this cycle with lots of clean-up. - Cross arch clean-up and consolidation of early DT scanning code. - Clean-up and removal of arch prom.h headers. Makes arch specific prom.h optional on all but Sparc. - Addition of interrupts-extended property for devices connected to multiple interrupt controllers. - Refactoring of DT interrupt parsing code in preparation for deferred probe of interrupts. - ARM cpu and cpu topology bindings documentation. - Various DT vendor binding documentation updates" * tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (82 commits) powerpc: add missing explicit OF includes for ppc dt/irq: add empty of_irq_count for !OF_IRQ dt: disable self-tests for !OF_IRQ of: irq: Fix interrupt-map entry matching MIPS: Netlogic: replace early_init_devtree() call of: Add Panasonic Corporation vendor prefix of: Add Chunghwa Picture Tubes Ltd. vendor prefix of: Add AU Optronics Corporation vendor prefix of/irq: Fix potential buffer overflow of/irq: Fix bug in interrupt parsing refactor. of: set dma_mask to point to coherent_dma_mask of: add vendor prefix for PHYTEC Messtechnik GmbH DT: sort vendor-prefixes.txt of: Add vendor prefix for Cadence of: Add empty for_each_available_child_of_node() macro definition arm/versatile: Fix versatile irq specifications. of/irq: create interrupts-extended property microblaze/pci: Drop PowerPC-ism from irq parsing of/irq: Create of_irq_parse_and_map_pci() to consolidate arch code. of/irq: Use irq_of_parse_and_map() ...

-* ARM CPUs binding description
+=================
+ARM CPUs bindings
+=================
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 ePAPR standard, available from:
-
-http://devicetree.org
-
-For the ARM architecture every CPU node must contain the following properties:
-
-- device_type: must be "cpu"
-- reg: property matching the CPU MPIDR[23:0] register bits
- reg[31:24] bits must be set to 0
-- compatible: should be one of:
- "arm,arm1020"
- "arm,arm1020e"
- "arm,arm1022"
- "arm,arm1026"
- "arm,arm720"
- "arm,arm740"
- "arm,arm7tdmi"
- "arm,arm920"
- "arm,arm922"
- "arm,arm925"
- "arm,arm926"
- "arm,arm940"
- "arm,arm946"
- "arm,arm9tdmi"
- "arm,cortex-a5"
- "arm,cortex-a7"
- "arm,cortex-a8"
- "arm,cortex-a9"
- "arm,cortex-a15"

-Example:
+Bindings for CPU nodes follow the ePAPR v1.1 standard, available from:
+
+https://www.power.org/documentation/epapr-version-1-1/
+
+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 ePAPR v1.1, 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 ePAPR, requires the cpus and cpu
+nodes to be present and contain the properties described below.
+
+- cpus node
+
+ Description: Container of cpu nodes
+
+ The node name must be "cpus".
+
+ A cpus node must define the following properties:
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+
+ Definition depends on ARM architecture version and
+ configuration:
+
+ # On uniprocessor ARM architectures previous to v7
+ value must be 1, to enable a simple enumeration
+ scheme for processors that do not have a HW CPU
+ identification register.
+ # On 32-bit ARM 11 MPcore, ARM v7 or later systems
+ value must be 1, that corresponds to CPUID/MPIDR
+ registers sizes.
+ # On ARM v8 64-bit systems value should be set to 2,
+ that corresponds to the MPIDR_EL1 register size.
+ If MPIDR_EL1[63:32] value is equal to 0 on all CPUs
+ in the system, #address-cells can be set to 1, since
+ MPIDR_EL1[63:32] bits are not used for CPUs
+ identification.
+ - #size-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be set to 0
+
+- cpu node
+
+ Description: Describes a CPU in an ARM based system
+
+ PROPERTIES
+
+ - device_type
+ Usage: required
+ Value type: <string>
+ Definition: must be "cpu"
+ - reg
+ 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.
+
+ - compatible:
+ Usage: required
+ Value type: <string>

+===========================================
+ARM topology binding description
+===========================================
+
+===========================================
+1 - Introduction
+===========================================
+
+In an ARM system, the hierarchy of CPUs is defined through three entities that
+are used to describe the layout of physical CPUs in the system:
+
+- cluster
+- core
+- thread
+
+The cpu nodes (bindings defined in [1]) represent the devices that
+correspond to physical CPUs and are to be mapped to the hierarchy levels.
+
+The bottom hierarchy level sits at core or thread level depending on whether
+symmetric multi-threading (SMT) is supported or not.
+
+For instance in a system where CPUs support SMT, "cpu" nodes represent all
+threads existing in the system and map to the hierarchy level "thread" above.
+In systems where SMT is not supported "cpu" nodes represent all cores present
+in the system and map to the hierarchy level "core" above.
+
+ARM topology bindings allow one to associate cpu nodes with hierarchical groups
+corresponding to the system hierarchy; syntactically they are defined as device
+tree nodes.
+
+The remainder of this document provides the topology bindings for ARM, based
+on the ePAPR standard, available from:
+
+http://www.power.org/documentation/epapr-version-1-1/
+
+If not stated otherwise, whenever a reference to a cpu node phandle is made its
+value must point to a cpu node compliant with the cpu node bindings as
+documented in [1].
+A topology description containing phandles to cpu nodes that are not compliant
+with bindings standardized in [1] is therefore considered invalid.
+
+===========================================
+2 - cpu-map node
+===========================================
+
+The ARM CPU topology is defined within the cpu-map node, which is a direct
+child of the cpus node and provides a container where the actual topology
+nodes are listed.
+
+- cpu-map node
+
+ Usage: Optional - On ARM SMP systems provide CPUs topology to the OS.
+ ARM uniprocessor systems do not require a topology
+ description and therefore should not define a
+ cpu-map node.
+
+ Description: The cpu-map node is just a container node where its
+ subnodes describe the CPU topology.
+
+ Node name must be "cpu-map".
+
+ The cpu-map node's parent node must be the cpus node.
+
+ The cpu-map node's child nodes can be:
+
+ - one or more cluster nodes
+
+ Any other configuration is considered invalid.
+
+The cpu-map node can only contain three types of child nodes:
+
+- cluster node
+- core node
+- thread node
+
+whose bindings are described in paragraph 3.
+
+The nodes describing the CPU topology (cluster/core/thread) can only be
+defined within the cpu-map node.
+Any other configuration is consider invalid and therefore must be ignored.
+
+===========================================
+2.1 - cpu-map child nodes naming convention
+===========================================
+
+cpu-map child nodes must follow a naming convention where the node name
+must be "clusterN", "coreN", "threadN" depending on the node type (ie
+cluster/core/thread) (where N = {0, 1, ...} is the node number; nodes which
+are siblings within a single common parent node must be given a unique and
+sequential N value, starting from 0).
+cpu-map child nodes which do not share a common parent node can have the same
+name (ie same number N as other cpu-map child nodes at different device tree
+levels) since name uniqueness will be guaranteed by the device tree hierarchy.
+
+===========================================
+3 - cluster/core/thread node bindings
+===========================================
+
+Bindings for cluster/cpu/thread nodes are defined as follows:
+
+- cluster node
+
+ Description: must be declared within a cpu-map node, one node
+ per cluster. A system can contain several layers of
+ clustering and cluster nodes can be contained in parent
+ cluster nodes.
+
+ The cluster node name must be "clusterN" as described in 2.1 above.
+ A cluster node can not be a leaf node.
+
+ A cluster node's child nodes must be:
+
+ - one or more cluster nodes; or
+ - one or more core nodes
+
+ Any other configuration is considered invalid.
+
+- core node
+
+ Description: must be declared in a cluster node, one node per core in
+ the cluster. If the system does not support SMT, core
+ nodes are leaf nodes, otherwise they become containers of
+ thread nodes.
+
+ The core node name must be "coreN" as described in 2.1 above.
+
+ A core node must be a leaf node if SMT is not supported.
+
+ Properties for core nodes that are leaf nodes:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to the
+ core node.
+
+ If a core node is not a leaf node (CPUs supporting SMT) a core node's
+ child nodes can be:
+
+ - one or more thread nodes
+
+ Any other configuration is considered invalid.
+
+- thread node
+
+ Description: must be declared in a core node, one node per thread
+ in the core if the system supports SMT. Thread nodes are
+ always leaf nodes in the device tree.
+
+ The thread node name must be "threadN" as described in 2.1 above.
+
+ A thread node must be a leaf node.
+
+ A thread node must contain the following property:
+
+ - cpu
+ Usage: required
+ Value type: <phandle>
+ Definition: a phandle to the cpu node that corresponds to
+ the thread node.

+interrupt client node or in any of its parent nodes. Interrupts listed in the

+
+The "interrupts-extended" property is a special form for use when a node needs
+to reference multiple interrupt parents. Each entry in this property contains
+both the parent phandle and the interrupt specifier. "interrupts-extended"

+ Example:
+ interrupts-extended = <&intc1 5 1>, <&intc2 1 0>;
+
+A device node may contain either "interrupts" or "interrupts-extended", but not
