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:
Bindings for CPU nodes follow the ePAPR v1.1 standard, available from:
http://devicetree.org
https://www.power.org/documentation/epapr-version-1-1/
For the ARM architecture every CPU node must contain the following properties:
with updates for 32-bit and 64-bit ARM systems provided in this document.
- device_type: must be "cpu"
- reg: property matching the CPU MPIDR[23:0] register bits
reg[31:24] bits must be set to 0

Convention used in this document
================================
Example:
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.

===========================================
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.

@ -4,16 +4,33 @@ Specifying interrupt information for devices
1) Interrupt client nodes
-------------------------
Nodes that describe devices which generate interrupts must contain an
"interrupts" property. This property must contain a list of interrupt
specifiers, one per output interrupt. The format of the interrupt specifier is
determined by the interrupt controller to which the interrupts are routed; see
section 2 below for details.
Nodes that describe devices which generate interrupts must contain an either an
"interrupts" property or an "interrupts-extended" property. These properties
contain a list of interrupt specifiers, one per output interrupt. The format of
the interrupt specifier is determined by the interrupt controller to which the
interrupts are routed; see section 2 below for details.
Example:
interrupt-parent = <&intc1>;
interrupts = <5 0>, <6 0>;
The "interrupt-parent" property is used to specify the controller to which
interrupts are routed and contains a single phandle referring to the interrupt
controller node. This property is inherited, so it may be specified in an
interrupt client node or in any of its parent nodes.
interrupt client node or in any of its parent nodes. Interrupts listed in the
"interrupts" property are always in reference to the node's interrupt parent.
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"
should only be used when a device has multiple interrupt parents.
Example:
interrupts-extended = <&intc1 5 1>, <&intc2 1 0>;
A device node may contain either "interrupts" or "interrupts-extended", but not
both. If both properties are present, then the operating system should log an
error and use only the data in "interrupts".
