==========================================
ARM idle states binding description
==========================================
==========================================
1 - Introduction
==========================================
ARM systems contain HW capable of managing power consumption dynamically,
where cores can be put in different low-power states (ranging from simple
wfi to power gating) according to OS PM policies. The CPU states representing
the range of dynamic idle states that a processor can enter at run-time, can be
specified through device tree bindings representing the parameters required
to enter/exit specific idle states on a given processor.
According to the Server Base System Architecture document (SBSA, [3]), the
power states an ARM CPU can be put into are identified by the following list:
- Running
- Idle_standby
- Idle_retention
- Sleep
- Off
The power states described in the SBSA document define the basic CPU states on
top of which ARM platforms implement power management schemes that allow an OS
PM implementation to put the processor in different idle states (which include
states listed above; "off" state is not an idle state since it does not have
wake-up capabilities, hence it is not considered in this document).
Idle state parameters (e.g. entry latency) are platform specific and need to be
characterized with bindings that provide the required information to OS PM
code so that it can build the required tables and use them at runtime.
The device tree binding definition for ARM idle states is the subject of this
document.
===========================================
2 - idle-states definitions
===========================================
Idle states are characterized for a specific system through a set of
timing and energy related properties, that underline the HW behaviour
triggered upon idle states entry and exit.
The following diagram depicts the CPU execution phases and related timing
properties required to enter and exit an idle state:
..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
| | | | |
|<------ entry ------->|
| latency |
|<- exit ->|
| latency |
|<-------- min-residency -------->|
|<------- wakeup-latency ------->|
Diagram 1: CPU idle state execution phases
EXEC: Normal CPU execution.
PREP: Preparation phase before committing the hardware to idle mode
like cache flushing. This is abortable on pending wake-up
event conditions. The abort latency is assumed to be negligible
(i.e. less than the ENTRY + EXIT duration). If aborted, CPU
goes back to EXEC. This phase is optional. If not abortable,
this should be included in the ENTRY phase instead.
ENTRY: The hardware is committed to idle mode. This period must run
to completion up to IDLE before anything else can happen.
IDLE: This is the actual energy-saving idle period. This may last
between 0 and infinite time, until a wake-up event occurs.
EXIT: Period during which the CPU is brought back to operational
mode (EXEC).
entry-latency: Worst case latency required to enter the idle state. The
exit-latency may be guaranteed only after entry-latency has passed.
min-residency: Minimum period, including preparation and entry, for a given
idle state to be worthwhile energywise.
wakeup-latency: Maximum delay between the signaling of a wake-up event and the
CPU being able to execute normal code again. If not specified, this is assumed
to be entry-latency + exit-latency.
These timing parameters can be used by an OS in different circumstances.
An idle CPU requires the expected min-residency time to select the most
appropriate idle state based on the expected expiry time of the next IRQ
(i.e. wake-up) that causes the CPU to return to the EXEC phase.
An operating system scheduler may need to compute the shortest wake-up delay
for CPUs in the system by detecting how long will it take to get a CPU out
of an idle state, e.g.:
wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
In other words, the scheduler can make its scheduling decision by selecting
(e.g. waking-up) the CPU with the shortest wake-up delay.
The wake-up delay must take into account the entry latency if that period
has not expired. The abortable nature of the PREP period can be ignored
if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
the worst case since it depends on the CPU operating conditions, i.e. caches
state).
An OS has to reliably probe the wakeup-latency since some devices can enforce
latency constraint guarantees to work properly, so the OS has to detect the
worst case wake-up latency it can incur if a CPU is allowed to enter an
idle state, and possibly to prevent that to guarantee reliable device
functioning.
The min-residency time parameter deserves further explanation since it is
expressed in time units but must factor in energy consumption coefficients.
The energy consumption of a cpu when it enters a power state can be roughly
characterised by the following graph:
|
|
|
e |
n | /---
e | /------
r | /------
g | /-----
y | /------
| ----
| /|
| / |
| / |
| / |
| / |
| / |
|/ |
-----|-------+----------------------------------
0| 1 time(ms)
Graph 1: Energy vs time example
The graph is split in two parts delimited by time 1ms on the X-axis.
The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
and denotes the energy costs incurred while entering and leaving the idle
state.
The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
shallower slope and essentially represents the energy consumption of the idle
state.
min-residency is defined for a given idle state as the minimum expected
residency time for a state (inclusive of preparation and entry) after
which choosing that state become the most energy efficient option. A good
way to visualise this, is by taking the same graph above and comparing some
states energy consumptions plots.
For sake of simplicity, let's consider a system with two idle states IDLE1,
and IDLE2:
|
|
|
| /-- IDLE1
e | /---
n | /----
e | /---
r | /-----/--------- IDLE2
g | /-------/---------
y | ------------ /---|
| / /---- |
| / /--- |
| / /---- |
| / /--- |
| --- |
| / |
| / |
|/ | time
---/----------------------------+------------------------
|IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
|
IDLE2-min-residency
Graph 2: idle states min-residency example
In graph 2 above, that takes into account idle states entry/exit energy
costs, it is clear that if the idle state residency time (i.e. time till next
wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
choice energywise.
This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
than IDLE2.
However, the lower power consumption (i.e. shallower energy curve slope) of
idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
efficient.
The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
shallower states in a system with multiple idle states) is defined
IDLE2-min-residency and corresponds to the time when energy consumption of
IDLE1 and IDLE2 states breaks even.
The definitions provided in this section underpin the idle states
properties specification that is the subject of the following sections.
===========================================
3 - idle-states node
===========================================
ARM processor idle states are defined within the idle-states node, which is
a direct child of the cpus node [1] and provides a container where the
processor idle states, defined as device tree nodes, are listed.
- idle-states node
Usage: Optional - On ARM systems, it is a container of processor idle
states nodes. If the system does not provide CPU
power management capabilities, or the processor just
supports idle_standby, an idle-states node is not
required.
Description: idle-states node is a container node, where its
subnodes describe the CPU idle states.
Node name must be "idle-states".
The idle-states node's parent node must be the cpus node.
The idle-states node's child nodes can be:
- one or more state nodes
Any other configuration is considered invalid.
An idle-states node defines the following properties:
- entry-method
Value type: <stringlist>
Usage and definition depend on ARM architecture version.
# On ARM v8 64-bit this property is required and must
be:
- "psci"
# On ARM 32-bit systems this property is optional
This assumes that the "enable-method" property is set to "psci" in the cpu
node[6] that is responsible for setting up CPU idle management in the OS
implementation.
The nodes describing the idle states (state) can only be defined
within the idle-states node, any other configuration is considered invalid
and therefore must be ignored.
===========================================
4 - state node
===========================================
A state node represents an idle state description and must be defined as
follows:
- state node
Description: must be child of the idle-states node
The state node name shall follow standard device tree naming
rules ([5], 2.2.1 "Node names"), in particular state nodes which
are siblings within a single common parent must be given a unique name.
The idle state entered by executing the wfi instruction (idle_standby
SBSA,[3][4]) is considered standard on all ARM platforms and therefore
must not be listed.
With the definitions provided above, the following list represents
the valid properties for a state node:
- compatible
Usage: Required
Value type: <stringlist>
Definition: Must be "arm,idle-state".
- local-timer-stop
Usage: See definition
Value type: <none>
Definition: if present the CPU local timer control logic is
lost on state entry, otherwise it is retained.
- entry-latency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing worst case latency in
microseconds required to enter the idle state.
- exit-latency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing worst case latency
in microseconds required to exit the idle state.
The exit-latency-us duration may be guaranteed
only after entry-latency-us has passed.
- min-residency-us
Usage: Required
Value type: <prop-encoded-array>
Definition: u32 value representing minimum residency duration
in microseconds, inclusive of preparation and
entry, for this idle state to be considered
worthwhile energy wise (refer to section 2 of
this document for a complete description).
- wakeup-latency-us:
Usage: Optional
Value type: <prop-encoded-array>
Definition: u32 value representing maximum delay between the
signaling of a wake-up event and the CPU being
able to execute normal code again. If omitted,
this is assumed to be equal to:
entry-latency-us + exit-latency-us
It is important to supply this value on systems
where the duration of PREP phase (see diagram 1,
section 2) is non-neglibigle.
In such systems entry-latency-us + exit-latency-us
will exceed wakeup-latency-us by this duration.
- status:
Usage: Optional
Value type: <string>
Definition: A standard device tree property [5] that indicates
the operational status of an idle-state.
If present, it shall be:
"okay": to indicate that the idle state is
operational.
"disabled": to indicate that the idle state has
been disabled in firmware so it is not
operational.
If the property is not present the idle-state must
be considered operational.
- idle-state-name:
Usage: Optional
Value type: <string>
Definition: A string used as a descriptive name for the idle
state.
In addition to the properties listed above, a state node may require
additional properties specific to the entry-method defined in the
idle-states node. Please refer to the entry-method bindings
documentation for properties definitions.

==========================================
1 - Introduction
==========================================
ARM systems contain HW capable of managing power consumption dynamically,
where cores can be put in different low-power states (ranging from simple wfi
to power gating) according to OS PM policies. The CPU states representing the
range of dynamic idle states that a processor can enter at run-time, can be
specified through device tree bindings representing the parameters required to
enter/exit specific idle states on a given processor.
According to the Server Base System Architecture document (SBSA, [3]), the
power states an ARM CPU can be put into are identified by the following list:
- Running
- Idle_standby
- Idle_retention
- Sleep
- Off
The power states described in the SBSA document define the basic CPU states on
top of which ARM platforms implement power management schemes that allow an OS
PM implementation to put the processor in different idle states (which include
states listed above; "off" state is not an idle state since it does not have
wake-up capabilities, hence it is not considered in this document).
Idle state parameters (e.g. entry latency) are platform specific and need to
be characterized with bindings that provide the required information to OS PM
code so that it can build the required tables and use them at runtime.
The device tree binding definition for ARM idle states is the subject of this
document.
===========================================
2 - idle-states definitions
===========================================
Idle states are characterized for a specific system through a set of
timing and energy related properties, that underline the HW behaviour
triggered upon idle states entry and exit.
The following diagram depicts the CPU execution phases and related timing
properties required to enter and exit an idle state:
..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
| | | | |
|<------ entry ------->|
| latency |
|<- exit ->|
| latency |
|<-------- min-residency -------->|
|<------- wakeup-latency ------->|
Diagram 1: CPU idle state execution phases
EXEC: Normal CPU execution.
PREP: Preparation phase before committing the hardware to idle mode
like cache flushing. This is abortable on pending wake-up
event conditions. The abort latency is assumed to be negligible
(i.e. less than the ENTRY + EXIT duration). If aborted, CPU
goes back to EXEC. This phase is optional. If not abortable,
this should be included in the ENTRY phase instead.
ENTRY: The hardware is committed to idle mode. This period must run
to completion up to IDLE before anything else can happen.
IDLE: This is the actual energy-saving idle period. This may last
between 0 and infinite time, until a wake-up event occurs.
EXIT: Period during which the CPU is brought back to operational
mode (EXEC).
entry-latency: Worst case latency required to enter the idle state. The
exit-latency may be guaranteed only after entry-latency has passed.
min-residency: Minimum period, including preparation and entry, for a given
idle state to be worthwhile energywise.
wakeup-latency: Maximum delay between the signaling of a wake-up event and the
CPU being able to execute normal code again. If not specified, this is assumed
to be entry-latency + exit-latency.
These timing parameters can be used by an OS in different circumstances.
An idle CPU requires the expected min-residency time to select the most
appropriate idle state based on the expected expiry time of the next IRQ
(i.e. wake-up) that causes the CPU to return to the EXEC phase.
An operating system scheduler may need to compute the shortest wake-up delay
for CPUs in the system by detecting how long will it take to get a CPU out
of an idle state, e.g.:
wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
In other words, the scheduler can make its scheduling decision by selecting
(e.g. waking-up) the CPU with the shortest wake-up delay.
The wake-up delay must take into account the entry latency if that period
has not expired. The abortable nature of the PREP period can be ignored
if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
the worst case since it depends on the CPU operating conditions, i.e. caches
state).
An OS has to reliably probe the wakeup-latency since some devices can enforce
latency constraint guarantees to work properly, so the OS has to detect the
worst case wake-up latency it can incur if a CPU is allowed to enter an
idle state, and possibly to prevent that to guarantee reliable device
functioning.
The min-residency time parameter deserves further explanation since it is
expressed in time units but must factor in energy consumption coefficients.
The energy consumption of a cpu when it enters a power state can be roughly
characterised by the following graph:
|
|
|
e |
n | /---
e | /------
r | /------
g | /-----
y | /------
| ----
| /|
| / |
| / |
| / |
| / |
| / |
|/ |
-----|-------+----------------------------------
0| 1 time(ms)
Graph 1: Energy vs time example
The graph is split in two parts delimited by time 1ms on the X-axis.
The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
and denotes the energy costs incurred while entering and leaving the idle
state.
The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
shallower slope and essentially represents the energy consumption of the idle
state.
min-residency is defined for a given idle state as the minimum expected
residency time for a state (inclusive of preparation and entry) after
which choosing that state become the most energy efficient option. A good
way to visualise this, is by taking the same graph above and comparing some
states energy consumptions plots.
For sake of simplicity, let's consider a system with two idle states IDLE1,
and IDLE2:
|
|
|
| /-- IDLE1
e | /---
n | /----
e | /---
r | /-----/--------- IDLE2
g | /-------/---------
y | ------------ /---|
| / /---- |
| / /--- |
| / /---- |
| / /--- |
| --- |
| / |
| / |
|/ | time
---/----------------------------+------------------------
|IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
|
IDLE2-min-residency
Graph 2: idle states min-residency example
In graph 2 above, that takes into account idle states entry/exit energy
costs, it is clear that if the idle state residency time (i.e. time till next
wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
choice energywise.
This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
than IDLE2.
However, the lower power consumption (i.e. shallower energy curve slope) of
idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
efficient.
The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
shallower states in a system with multiple idle states) is defined
IDLE2-min-residency and corresponds to the time when energy consumption of
IDLE1 and IDLE2 states breaks even.
The definitions provided in this section underpin the idle states
properties specification that is the subject of the following sections.
===========================================
3 - idle-states node
===========================================
ARM processor idle states are defined within the idle-states node, which is
a direct child of the cpus node [1] and provides a container where the
processor idle states, defined as device tree nodes, are listed.
On ARM systems, it is a container of processor idle states nodes. If the
system does not provide CPU power management capabilities, or the processor
just supports idle_standby, an idle-states node is not required.

Each state node represents an idle state description and must be defined

The idle state entered by executing the wfi instruction (idle_standby
SBSA,[3][4]) is considered standard on all ARM platforms and therefore
must not be listed.
In addition to the properties listed above, a state node may require
additional properties specific to the entry-method defined in the
idle-states node. Please refer to the entry-method bindings

ARM systems can have multiple cores, sometimes in an hierarchical
arrangement. This often, but not always, maps directly to the processor
power topology of the system. Individual nodes in a topology have their
own specific power states and can be better represented hierarchically.
For these cases, the definitions of the idle states for the CPUs and the
CPU topology, must conform to the binding in [3]. The idle states
themselves must conform to the binding in [4] and must specify the
arm,psci-suspend-param property.
It should also be noted that, in PSCI firmware v1.0 the OS-Initiated
(OSI) CPU suspend mode is introduced. Using a hierarchical representation
helps to implement support for OSI mode and OS implementations may choose
to mandate it.

ML-AHB interconnect bindings
These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
a Cortex-M subsystem with dedicated memories.
The MCU SRAM and RETRAM memory parts can be accessed through different addresses
(see "RAM aliases" in [1]) using different buses (see [2]) : balancing the
Cortex-M firmware accesses among those ports allows to tune the system
performance.
[1]: https://www.st.com/resource/en/reference_manual/dm00327659.pdf
[2]: https://wiki.st.com/stm32mpu/wiki/STM32MP15_RAM_mapping
Required properties:
- compatible: should be "simple-bus"
- dma-ranges: describes memory addresses translation between the local CPU and
the remote Cortex-M processor. Each memory region, is declared with
3 parameters:
- param 1: device base address (Cortex-M processor address)
- param 2: physical base address (local CPU address)
- param 3: size of the memory region.
The Cortex-M remote processor accessed via the mlahb interconnect is described
by a child node.
Example:
mlahb {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
dma-ranges = <0x00000000 0x38000000 0x10000>,

* Faraday Technology FTIDE010 PATA controller
This controller is the first Faraday IDE interface block, used in the
StorLink SL2312 and SL3516, later known as the Cortina Systems Gemini
platform. The controller can do PIO modes 0 through 4, Multi-word DMA
(MWDM)modes 0 through 2 and Ultra DMA modes 0 through 6.
On the Gemini platform, this PATA block is accompanied by a PATA to
SATA bridge in order to support SATA. This is why a phandle to that
controller is compulsory on that platform.
The timing properties are unique per-SoC, not per-board.
Required properties:
- compatible: should be one of
"cortina,gemini-pata", "faraday,ftide010"
"faraday,ftide010"
- interrupts: interrupt for the block
- reg: registers and size for the block
Optional properties:
- clocks: a SoC clock running the peripheral.
- clock-names: should be set to "PCLK" for the peripheral clock.
Required properties for "cortina,gemini-pata" compatible:
- sata: a phande to the Gemini PATA to SATA bridge, see
cortina,gemini-sata-bridge.txt for details.
Example:
ata@63000000 {
compatible = "cortina,gemini-pata", "faraday,ftide010";
reg = <0x63000000 0x100>;
interrupts = <4 IRQ_TYPE_EDGE_RISING>;
clocks = <&gcc GEMINI_CLK_GATE_IDE>;
clock-names = "PCLK";
sata = <&sata>;

- Michael Walle <michael@walle.cc>
description: |
It is possible to use the BCLK pin of a SAI module as a generic clock
output. Some SoC are very constrained in their pin multiplexer
configuration. Eg. pins can only be changed groups. For example, on the
LS1028A SoC you can only enable SAIs in pairs. If you use only one SAI,
the second pins are wasted. Using this binding it is possible to use the
clock of the second SAI as a MCLK clock for an audio codec, for example.
This is a composite of a gated clock and a divider clock.
