Zephyr 3.1.0
############

The following sections provide detailed lists of changes by component.

API Changes
***********

Changes in this release
=======================

* All Zephyr public headers have been moved to ``include/zephyr``, meaning they
  need to be prefixed with ``<zephyr/...>`` when included. Because this change
  can potentially break many applications or libraries,
  :kconfig:option:`CONFIG_LEGACY_INCLUDE_PATH` is provided to allow using the
  old include path. This option is now enabled by default to allow a smooth
  transition. In order to facilitate the migration to the new include prefix, a
  script to automate the process is also provided:
  :zephyr_file:`scripts/utils/migrate_includes.py`.

* LoRaWAN: The message type parameter in :c:func:`lorawan_send` was changed
  from ``uint8_t`` to ``enum lorawan_message_type``. If ``0`` was passed for
  unconfirmed message, this has to be changed to ``LORAWAN_MSG_UNCONFIRMED``.
* Bluetooth: Applications where :kconfig:option:`CONFIG_BT_EATT` is enabled
  must set the :c:member:`chan_opt` field on the GATT parameter structs.
  To keep the old behavior use :c:enumerator:`BT_ATT_CHAN_OPT_NONE`.

* Disk Subsystem: SPI mode SD cards now use the SD subsystem to communicate
  with SD cards. See :ref:`the disk access api <disk_access_api>` for an
  example of the new devicetree binding format required.

* Kconfig preprocessor function ``dt_nodelabel_has_compat`` was redefined, for
  consistency with the ``dt_nodelabel_has_prop`` function and devicetree macros
  like :c:func:`DT_NODE_HAS_COMPAT`. Now the function does not take into account
  the status of the checked node. Its former functionality is provided by the
  newly introduced ``dt_nodelabel_enabled_with_compat`` function.

* CAN

  * Added ``const struct device`` parameter to the following CAN callback function signatures:

    * ``can_tx_callback_t``
    * ``can_rx_callback_t``
    * ``can_state_change_callback_t``

  * Allow calling the following CAN API functions from userspace:

    * :c:func:`can_set_mode()`
    * :c:func:`can_calc_timing()`
    * :c:func:`can_calc_timing_data()`
    * :c:func:`can_set_bitrate()`
    * :c:func:`can_get_max_filters()`

  * Changed :c:func:`can_set_bitrate()` to use a sample point of 75.0% for bitrates over 800 kbit/s,
    80.0% for bitrates over 500 kbit/s, and 87.5% for all other bitrates.

  * Split CAN classic and CAN-FD APIs:

    * :c:func:`can_set_timing()` split into :c:func:`can_set_timing()` and
      :c:func:`can_set_timing_data()`.
    * :c:func:`can_set_bitrate()` split into :c:func:`can_set_bitrate()` and
      :c:func:`can_set_bitrate_data()`.

  * Converted the ``enum can_mode`` into a ``can_mode_t`` bitfield and renamed the CAN mode
    definitions:

    * ``CAN_NORMAL_MODE`` renamed to :c:macro:`CAN_MODE_NORMAL`.
    * ``CAN_SILENT_MODE`` renamed to :c:macro:`CAN_MODE_LISTENONLY`.
    * ``CAN_LOOPBACK_MODE`` renamed to :c:macro:`CAN_MODE_LOOPBACK`.
    * The previous ``CAN_SILENT_LOOPBACK_MODE`` can be set using the bitmask ``(CAN_MODE_LISTENONLY |
      CAN_MODE_LOOPBACK)``.

  * STM32H7: :kconfig:option:`CONFIG_NOCACHE_MEMORY` is no longer responsible for disabling
    data cache when defined. Use ``CONFIG_DCACHE=n`` instead.

  * Converted the STM32F1 pin nodes configuration names to include remap information (in
    cases other than NO_REMAP/REMAP_0)
    For instance:

    * ``i2c1_scl_pb8`` renamed to ``i2c1_scl_remap1_pb8``

Removed APIs in this release
============================

* STM32F1 Serial wire JTAG configuration (SWJ CFG) configuration choice
  was moved from Kconfig to :ref:`devicetree <dt-guide>`.
  See the :dtcompatible:`st,stm32f1-pinctrl` devicetree binding for more information.
  As a consequence, the following Kconfig symbols were removed:

  * ``CONFIG_GPIO_STM32_SWJ_ENABLE``
  * ``CONFIG_GPIO_STM32_SWJ_NONJTRST``
  * ``CONFIG_GPIO_STM32_SWJ_NOJTAG``
  * ``CONFIG_GPIO_STM32_SWJ_DISABLE``

* Removed experimental 6LoCAN protocol support.

* Removed the following deprecated CAN APIs:

  * Custom CAN error codes
  * ``can_configure()``
  * ``can_attach_workq()``
  * ``can_attach_isr()``
  * ``can_attach_msgq()``
  * ``can_detach()``
  * ``can_register_state_change_isr()``
  * ``can_write()``

Deprecated in this release
==========================

* :c:func:`nvs_init` is deprecated in favor of utilizing :c:func:`nvs_mount`.
* :c:func:`lwm2m_engine_set_res_data` is deprecated in favor of :c:func:`lwm2m_engine_set_res_buf`
* :c:func:`lwm2m_engine_get_res_data` is deprecated in favor of :c:func:`lwm2m_engine_get_res_buf`
* The TinyCBOR module has been deprecated in favor of the new zcbor CBOR
  library, included with Zephyr in this release.

* GPIO

  * Deprecated the ``GPIO_INT_DEBOUNCE`` flag and the ``GPIO_DS_*`` and
    ``GPIO_VOLTAGE_*`` groups of flags. Controller/SoC specific flags
    should now be used instead.

* SPI

  * Deprecated the ``gpio_dev``, ``gpio_pin``, and ``gpio_dt_flags`` members in
    struct :c:struct:`spi_cs_control` in favor of a new struct
    :c:struct:`gpio_dt_spec` member named ``gpio``.

* PWM

  * The ``pin`` prefix has been removed from all PWM API calls. So for example,
    ``pwm_pin_set_cycles`` is now ``pwm_set_cycles``. The old API calls are
    still provided, but are now deprecated.
  * PWM periods are now always set in nanoseconds, so ``_nsec`` and ``_usec``
    set functions such as ``pwm_pin_set_nsec()`` and ``pwm_pin_set_usec()``
    have been deprecated. Other units can be specified using, e.g.
    ``PWM_USEC()`` macros, which convert other units to nanoseconds.

* Utilities

  * :c:macro:`UTIL_LISTIFY` has been deprecated. Use :c:macro:`LISTIFY` instead.

* Mesh

  * The following functions related to the Bluetooth Mesh Health Client model:

    * :c:func:`bt_mesh_health_fault_get()` replace with :c:func:`bt_mesh_health_cli_fault_get()`
    * :c:func:`bt_mesh_health_fault_clear()` replace with :c:func:`bt_mesh_health_cli_fault_clear()`
    * :c:func:`bt_mesh_health_fault_clear_unack()` replace with :c:func:`bt_mesh_health_cli_fault_clear_unack()`

    * :c:func:`bt_mesh_health_period_get()` replace with :c:func:`bt_mesh_health_cli_period_get()`
    * :c:func:`bt_mesh_health_period_set()` replace with :c:func:`bt_mesh_health_cli_period_set()`
    * :c:func:`bt_mesh_health_period_set_unack()` replace with :c:func:`bt_mesh_health_cli_period_set_unack()`
    * :c:func:`bt_mesh_health_attention_get()` replace with :c:func:`bt_mesh_health_cli_attention_get()`
    * :c:func:`bt_mesh_health_attention_set()` replace with :c:func:`bt_mesh_health_cli_attention_set()`
    * :c:func:`bt_mesh_health_attention_set_unack()` replace with :c:func:`bt_mesh_health_cli_attention_set_unack()`

  * The following function related to the Bluetooth Mesh Health Server model:

    * :c:func:`bt_mesh_fault_update()` replace with :c:func:`bt_mesh_health_srv_fault_update()`

    closes HCI transport.
  * Implemented :c:member:`bt_hci_driver.close` on stm32wb HCI driver.

* Host

  * The :c:enum:`bt_l2cap_chan_state` values ``BT_L2CAP_CONNECT`` and
    ``BT_L2CAP_DISCONNECT`` have been renamed to ``BT_L2CAP_CONNECTING`` and
    ``BT_L2CAP_DISCONNECTING`` respectively.

  * The callbacks :c:func:`pairing_complete`, :c:func:`pairing_failed`, and
    :c:func:`bond_delete` have been moved from struct :c:struct:`bt_auth_cb` to a
    newly created informational-only callback struct :c:struct:`bt_conn_auth_info_cb`.

  * :c:func:`bt_conn_index` now takes a ``const struct bt_conn*`` argument.

  * The :c:struct:`bt_gatt_subscribe_params` structure's ``write`` callback
    function has been deprecated.  Use the new ``subscribe`` callback
    instead.

  * :c:func:`bt_disable` was added to enable the caller to disable the Bluetooth stack.

  * Added new Kconfig options to select ISO Central and Peripheral role support
    separately

  * Added a new :c:func:`bt_get_appearance()` API call

  * Implemented support for dynamic appearance, including a new
    :c:func:`bt_set_appearance()` API call

  * Implemented support for L2CAP collision mitigation

  * Changed the scheduling of auto-initiated HCI commands so that they execute
    synchronously

  * Added a new :c:func:`bt_is_ready()` API call to find out if Bluetooth is
    currently enabled and initialized

  * Added support for automatic MTU exchange right after a connection is
    established

  * Created a new :c:struct:`bt_conn_auth_info_cb` to group the
    security-related callbacks under a single struct

  * Optimized the memory usage of the Object Transfer Service

  * Added a new :c:func:`bt_hci_le_rand()` API call to obtain a random number
    from the LE Controller

  * Optimized L2CAP channels resource usage when not using dynamic channels

  * Added the ability to run the Bluetooth RX context from a workqueue, in order
    to optimize RAM usage. See :kconfig:option:`CONFIG_BT_RECV_CONTEXT`.

  * Added support for TX complete callback on EATT channels

  * Corrected the calling of the MTU callback to happen on any reconfiguration

Kernel
******

* Aborting an essential thread now causes a kernel panic, as the
  documentation has always promised but the kernel has never
  implemented.

* The k_timer handler can now correct itself for lost time due to very
  late-arriving interrupts.

* SMP interprocessor interrupts are deferred so that they are sent only at
  schedule points, and not synchronously when the scheduler state
  changes.  This prevents IPI "storms" with code that does many
  scheduler operations at once (e.g. waking up a bunch of threads).

* The timeslicing API now allows slice times to be controlled
  independently for each thread, and provides a callback to the app
  when a thread timeslice has expired.  The intent is that this will
  allow apps the tools to implement CPU resource control algorithms
  (e.g. fairness or interactivity metrics, budget tracking) that are
  out of scope for Zephyr's deterministic RTOS scheduler.

Architectures
*************

* ARC

  * Added ARCv3 32 bit (HS5x) support - both GNU and MWDT toolchains, both UP and SMP
  * Worked around debug_select interference with MDB debugger
  * Switched to hs6x mcpu usage (GNU toolchain) for HS6x

* ARM

  * AARCH32

    * Added Cortex-R floating point support

    * Added more memory mapping types for device memory
    * Simplified and optimize switching and user mode transition code
    * Added support for CONFIG_IRQ_OFFLOAD_NESTED
    * Fixed booting issue with FVP V8R >= 11.16.16
    * Switched to the IRQ stack during ISR execution

* Xtensa

  * Optimized context switches when KERNEL_COHERENCE is enabled to
    avoid needless stack invalidations for threads that have not
    migrated between CPUs.

  * Fixed a bug that could return directly into a thread context from a
    nested interrupt instead of properly returning to the preempted
    ISR.

* x64_64

  * UEFI devices can now use the firmware-initialized system console
    API as a printk/logging backend, simplifying platform bringup on
    devices without known-working serial port configurations.

  * STM32: Added support for :c:enumerator:`adc_reference.ADC_REF_INTERNAL`.
  * Added the :c:struct:`adc_dt_spec` structure and associated helper macros,
    e.g. :c:macro:`ADC_DT_SPEC_GET`, to facilitate getting configuration of
    ADC channels from devicetree nodes.

* CAN

  * Switched from transmitting CAN frames in FIFO/chronological order to transmitting according to
    CAN-ID priority (NXP FlexCAN, ST STM32 bxCAN, Bosch M_CAN, Microchip MCP2515).
  * Added support for ST STM32U5 to the ST STM32 FDCAN driver.
  * Renamed the base Bosch M_CAN devicetree binding compatible from ``bosch,m-can-base`` to
    :dtcompatible:`bosch,m_can-base`.
  * Added CAN controller statistics support (NXP FlexCAN, Renesas R-Car, ST STM32 bxCAN).
  * Added CAN transceiver support.
  * Added generic SocketCAN network interface and removed driver-specific implementations.

* Clock_control

  * STM32: Driver was cleaned up and overhauled for easier maintenance with a deeper integration
    of device tree inputs. Driver now takes into account individual activation of clock sources
    (High/Medium/Low Internal/external speed clocks, PLLs, ...)
  * STM32: Additionally to above change it is now possible for clock consumers to select an alternate
    source clock (Eg: LSE) by adding it to its 'clocks' property and then configure it using new
    clock_control_configure() API.
    See :dtcompatible:`st,stm32-rcc`, :dtcompatible:`st,stm32h7-rcc` and :dtcompatible:`st,stm32u5-rcc`
    for more information.

* Counter

    disk devices. This disk driver will be used with any disk device declared
    with the ``zephyr,sdmmc-disk`` compatible string.

* Display

  * STM32: Added basic support for LTDC driver. Currently supported on F4, F7, H7, L4+
    and MP1 series.

  * Added a scatter gather test for DMAs that support it
  * Cleanly shared Synopsis DW-DMA driver and Intel cAVS GPDMA driver code.
  * Added support for Synposis DW-DMA transfer lists.
  * Added support for Intel HDA for audio device and host streams.
  * Fixes for NXP eDMA to pass scatter gather tests

  * eth_liteeth: Refactored driver to use LiteX HAL.
  * eth_w5500: Fixed possible deadlock due to incorrect IRQ processing.

* Flash

  * Added STM32 OCTOSPI driver. Initial support is provided for L5 and U5
    series. Interrupt driven mode. Supports 1 and 8 lines in Single or Dual
    Transfer Modes.
  * STM32L5: Added support for Single Bank.
  * STM32 QSPI driver was extended with QER (SFDP, DTS), custom quad write opcode
    and 1-1-4 read mode.
  * Added support for STM32U5 series.

* GPIO

  * Refactored GPIO devicetree flags. The upper 8 bits of ``gpio_dt_flags_t``
    are now reserved for controller/SoC specific flags. Certain
    hardware-specific flags previously defined as common configuration (IO
    voltage level, drive strength, and debounce filter) were replaced with ones
    defined in this controller/SoC specific space.
  * Added Xilinx PS MIO/EMIO GPIO controller driver.
  * Extended the NXP PCA95XX driver to support also PCAL95XX.

* HWINFO

  * Atmel SAM: Added RSTC support
  * Raspberry Pi Pico: Added Unique ID and reset cause driver

* I2C

  * Added arbitrary I2C clock speed support with :c:macro:`I2C_SPEED_DT`
  * NXP flexcomm now supports target (slave) mode
  * Fixed Atmel SAM/SAM0 exclusive bus access
  * Added ITE support

* I2S

  * Ported I2S drivers to pinctrl.
  * Fixed multiple bugs in the NXP I2S (SAI) driver, including problems with
    DMA transmission and FIFO under/overruns.

* MEMC

  * STM32: Extended FMC driver to support NOR/PSRAM. See :dtcompatible:`st,stm32-fmc-nor-psram.yaml`.

* Pin control

  * Platform support was added for:

    * Atmel SAM/SAM0
    * Espressif ESP32
    * ITE IT8XXX2
    * Microchip XEC
    * Nordic nRF (completed support)
    * Nuvoton NPCX Embedded Controller (EC)
    * NXP iMX
    * NXP Kinetis
    * NXP LPC
    * RV32M1
    * SiFive Freedom
    * Telink B91
    * TI CC13XX/CC26XX

  * STM32: It is now possible to configure plain GPIO pins using the pinctrl API.
    See :dtcompatible:`st,stm32-pinctrl` and :dtcompatible:`st,stm32f1-pinctrl` for
    more information.

* PWM

  * Added :c:struct:`pwm_dt_spec` and associated helpers, e.g.
    :c:macro:`PWM_DT_SPEC_GET` or :c:func:`pwm_set_dt`. This addition makes it
    easier to use the PWM API when the PWM channel, period and flags are taken
    from a devicetree PWM cell.
  * STM32: Enabled complementary output for timer channel. A PWM consumer can now use
    :c:macro:`PWM_STM32_COMPLEMENTARY` to specify that PWM output should happen on a
    complementary channel pincfg (eg:``tim1_ch2n_pb14``).
  * STM32: Added counter mode support. See :dtcompatible:`st,stm32-timers`.
  * Aligned nRF PWM drivers (pwm_nrfx and pwm_nrf5_sw) with the updated PWM API.
    In particular, this means that the :c:func:`pwm_set` and
    :c:func:`pwm_set_cycles` functions need to be called with a PWM channel
    as a parameter, not with a pin number like it was for the deprecated
    ``pwm_pin_set_*`` functions. Also, the ``flags`` parameter is now supported
    by the drivers, so either the :c:macro:`PWM_POLARITY_INVERTED` or
    :c:macro:`PWM_POLARITY_NORMAL` flag must be provided in each call.

* Reset

  * Added reset controller driver API.
  * Raspberry Pi Pico: Added reset controller driver

* Sensor

  * Added NCPX ADC comparator driver.

  * Removed redundant DEV_NAME helpers in various drivers.
  * Enhanced the LIS2DH driver to support device power management.
  * Fixed overflow issue in sensor_value_from_double().
  * Added MAX31875 temperature sensor driver.

* Serial

  * STM32: Added tx/rx pin swap and rx invert / tx invert capabilities.

* SPI

  * Ported all SPI drivers to pinctrl
  * Added support for SPI on the GD32 family

* Timer

  * Ported timer drivers to use pinctrl
  * LiteX: Ported the timer driver to use the HAL

* USB

  * Added RP2040 (Raspberry Pi Pico) USB device controller driver

Networking
**********

* CoAP:

  * Changed :c:struct:`coap_pending` allocation criteria. This now uses a data
    pointer instead of a timestamp, which does not give a 100% guarantee that
    structure is not in use already.

* Ethernet:

  * Added a
    :kconfig:option:`CONFIG_NET_ETHERNET_FORWARD_UNRECOGNISED_ETHERTYPE`
    option, which allows to forward frames with unrecognised EtherType to the
    network stack.

* HTTP:

  * Removed a limitation where the maximum content length was limited up to
    100000 bytes.
  * Fixed ``http_client_req()`` return value. The function now correctly
    reports the number of bytes sent.
  * Clarified the expected behavior in case of empty response from the server.
  * Made use of ``shutdown`` to tear down HTTP connection instead of
    closing the socket from a system work queue.

* LwM2M:

  * Various improvements towards LwM2M 1.1 support:

    * Added LwM2M 1.1 Discovery support.
    * Added attribute handling for Resource Instances.
    * Added support for Send, Read-composite, Write-composite, Observe-composite
      operations.
    * Added new content formats: SenML JSON, CBOR, SenML CBOR.
    * Added v1.1 implementation of core LwM2M objects.

  * Added support for dynamic Resource Instance allocation.
  * Added support for LwM2M Portfolio object (Object ID 16).
  * Added LwM2M shell module.
  * Added option to utilize DTLS session cache in queue mode.
  * Added :c:func:`lwm2m_engine_path_is_observed` API function.
  * Fixed a bug with hostname verification setting, which prevented DTLS
    connection in certain mbedTLS configurations.
  * Fixed a bug which could cause a socket descriptor leak, in case
    :c:func:`lwm2m_rd_client_start` was called immediately after
    :c:func:`lwm2m_rd_client_stop`.
  * Added error reporting from :c:func:`lwm2m_rd_client_start` and
    :c:func:`lwm2m_rd_client_stop`.

* Misc:

  * Added :c:func:`net_if_set_default` function which allows to set a default
    network interface at runtime.
  * Added :kconfig:option:`CONFIG_NET_DEFAULT_IF_UP` option which allows to make the
    first interface which is up the default choice.
  * Fixed packet leak in network shell TCP receive handler.
  * Added :c:func:`net_pkt_rx_clone` which allows to allocated packet from
    correct packet pool when cloning. This is used at the loopback interface.
  * Added :kconfig:option:`CONFIG_NET_LOOPBACK_SIMULATE_PACKET_DROP` option which
    allows to simulate packet drop at the loopback interface. This is used by
    certain test cases.

* MQTT:

  * Removed custom logging macros from MQTT implementation, in favour of the
    common networking logging.

* OpenThread:

  * Updated OpenThread revision up to commit ``130afd9bb6d02f2a07e86b824fb7a79e9fca5fe0``.
  * Implemented ``otPlatCryptoRand`` platform API for OpenThread.
  * Added support for PSA MAC keys.
  * Multiple minor fixes/improvements to align with upstream OpenThread changes.

* Sockets:

  * Added support for ``shutdown()`` function.
  * Fixed ``sendmsg()`` operation when TCP reported full transmission window.
  * Added support for ``getpeername()`` function.
  * Fixed userspace ``accept()`` argument validation.
  * Added support for :c:macro:`SO_SNDBUF` and :c:macro:`SO_RCVBUF` socket
    options.
  * Implemented ``POLLOUT`` reporting from ``poll()`` for STREAM
    sockets.
  * Implemented socket dispatcher for offloaded sockets. This module allows to
    use multiple offloaded socket implementations at the same time.
  * Introduced a common socket priority for offloaded sockets
    (:kconfig:option:`CONFIG_NET_SOCKETS_OFFLOAD_PRIORITY`).
  * Moved socket offloading out of experimental.

* TCP:

  * Implemented receive window handling.
  * Implemented zero-window probe processing and sending.
  * Improved TCP stack throughput over loopback interface.
  * Fixed possible transmission window overflow in case of TCP retransmissions.
    This could led to TX buffer starvation when TCP entered retransmission mode.
  * Updated ``FIN_TIMEOUT`` delay to correctly reflect time needed for
    all FIN packet retransmissions.
  * Added proper error reporting from TCP to upper layers. This solves the
    problem of connection errors being reported to the application as graceful
    connection shutdown.
  * Added a mechanism which allows upper layers to monitor the TCP transmission
    window availability. This allows to improve throughput greatly in low-buffer
    scenarios.

* TLS:

  * Added :c:macro:`TLS_SESSION_CACHE` and :c:macro:`TLS_SESSION_CACHE_PURGE`
    socket options which allow to control session caching on a socket.
  * Fixed :c:macro:`TLS_CIPHERSUITE_LIST` socket option, which did not set the
    cipher list on a socket correctly.

USB
***

* Moved USB device stack code to own directory in preparation for upcoming
  rework of USB support.

Build System
************

* The build system's internals have been completely overhauled for increased
  modularity. This makes it easier to reuse individual components through the
  Zephyr CMake package mechanism.

  With the improved Zephyr CMake package, the following examples are now possible:

  * ``find_package(Zephyr)``: load a standard build system, as before
  * ``find_package(Zephyr COMPONENTS unittest)``: load a specific unittest
    build component
  * ``find_package(Zephyr COMPONENTS dts)``: only load the dts module and its
    direct dependencies
  * ``find_package(Zephyr COMPONENTS extensions west zephyr_module)``: load
    multiple specific modules and their dependencies

  Some use cases that this work intends to enable are:

  * The sysbuild proposal: `Zephyr sysbuild / multi image #40555
    <https://github.com/zephyrproject-rtos/zephyr/pull/40555>`_
  * Running Zephyr CMake configure stages individually. One example is only
    processing the devicetree steps of the build system, while skipping the
    rest. This is a required feature for extending twister to do test case
    filtering based on the devicetree contents without invoking a complete
    CMake configuration.

  For more details, see :zephyr_file:`cmake/package_helper.cmake`.

* A new Zephyr SDK has been created which now supports macOS and Windows in
  addition to Linux platforms.

  For more information, see: https://github.com/zephyrproject-rtos/sdk-ng

Devicetree
**********

* API

  * New macros for creating tokens in C from strings in the devicetree:
    :c:macro:`DT_STRING_UPPER_TOKEN_OR`, :c:macro:`DT_INST_STRING_TOKEN`,
    :c:macro:`DT_INST_STRING_UPPER_TOKEN`,
    :c:macro:`DT_INST_STRING_UPPER_TOKEN_OR`

  * :ref:`devicetree-can-api`: new

* Bindings

  * Several new bindings were created to support :ref:`Pin Control
    <pinctrl-guide>` driver API implementations. This also affected many
    peripheral bindings, which now support ``pinctrl-0``, ``pinctrl-1``, ...,
    and ``pinctrl-names`` properties used to configure peripheral pin
    assignments in different system states, such as active and low-power
    states.

    In some cases, this resulted in the removal of old bindings, or other
    backwards incompatible changes affecting users of the old bindings. These
    changes include:

    * :dtcompatible:`atmel,sam-pinctrl` and :dtcompatible:`atmel,sam0-pinctrl`
      have been adapted to the new pinctrl bindings interface
    * :dtcompatible:`espressif,esp32-pinctrl` has replaced ``espressif,esp32-pinmux``
    * :dtcompatible:`ite,it8xxx2-pinctrl` and
      :dtcompatible:`ite,it8xxx2-pinctrl-func` have replaced
      ``ite,it8xxx2-pinmux`` and ``ite,it8xxx2-pinctrl-conf``
    * :dtcompatible:`microchip,xec-pinctrl`: new
    * :dtcompatible:`nuvoton,npcx-pinctrl`: new
    * :dtcompatible:`nxp,kinetis-pinctrl` has replaced the ``nxp,kinetis-port-pins`` property found in the ``nxp,kinetis-pinmux`` binding.
    * :dtcompatible:`nxp,mcux-rt-pinctrl`,
      :dtcompatible:`nxp,mcux-rt11xx-pinctrl`,
      :dtcompatible:`nxp,lpc-iocon-pinctrl`, :dtcompatible:`nxp,rt-iocon-pinctrl`,
      :dtcompatible:`nxp,lpc11u6x-pinctrl`, :dtcompatible:`nxp,imx7d-pinctrl`,
      :dtcompatible:`nxp,imx8m-pinctrl`, :dtcompatible:`nxp,imx8mp-pinctrl` and
      :dtcompatible:`nxp,imx-iomuxc`: new
    * :dtcompatible:`openisa,rv32m1-pinctrl`: new
    * :dtcompatible:`sifive,pinctrl` has replaced ``sifive,iof``
    * :dtcompatible:`telink,b91-pinctrl` has replaced ``telink,b91-pinmux``
    * :dtcompatible:`ti,cc13xx-cc26xx-pinctrl` has replaced ``ti,cc13xx-cc26xx-pinmux``

  * PWM bindings now generally have ``#pwm-cells`` set to 3, not 2 as it was in
    previous releases. This was done to follow the Linux convention that each
    PWM specifier should contain a channel, period, and flags cell, in that
    order. See pull request `#44523
    <https://github.com/zephyrproject-rtos/zephyr/pull/44523>`_ for more
    details on this change and its purpose.

  * Some bindings had their :ref:`compatible properties <dt-important-props>`
    renamed:

    * :dtcompatible:`nxp,imx-elcdif` has replaced ``fsl,imx6sx-lcdif``
    * :dtcompatible:`nxp,imx-gpr` has replaced ``nxp,imx-pinmux``
    * :dtcompatible:`nordic,nrf-wdt` has replaced ``nordic,nrf-watchdog``
    * :dtcompatible:`bosch,m_can-base` has replaced ``bosch,m-can-base``
    * :dtcompatible:`nxp,imx-usdhc` has replaced ``nxp,imx-sdhc``

  * Bindings with ``resets`` (and optionally ``reset-names``) properties were
    added to support the :ref:`reset_api` API. See the list of new bindings
    below for some examples.

  * The ``zephyr,memory-region-mpu`` property can be set to generate MPU
    regions from devicetree nodes. See commit `b91d21d32c
    <https://github.com/zephyrproject-rtos/zephyr/commit/b91d21d32ccc312558babe2cc363afbe44ea2de2>`_

  * The generic :zephyr_file:`dts/bindings/can/can-controller.yaml` include
    file used for defining CAN controller bindings no longer contains a ``bus:
    yaml`` statement. This was unused in upstream Zephyr; out of tree bindings
    relying on this will need updates.

  * Bindings for ADC controller nodes can now use a child binding to specify
    the initial configuration of individual channels in devicetree. See pull
    request `43030 <https://github.com/zephyrproject-rtos/zephyr/pull/43030>`_
    for details.

Libraries / Subsystems
**********************

* C Library

  * Minimal libc

    * Added ``[U]INT_{FAST,LEAST}N_{MIN,MAX}`` minimum and maximum value
      macros in ``stdint.h``.
    * Added ``PRIx{FAST,LEAST}N`` and ``PRIxMAX`` format specifier macros in
      ``inttypes.h``.
    * Fixed ``gmtime()`` access fault when userspace is enabled and
      ``gmtime()`` is called from a user mode thread. This function can be
      safely called from both kernel and user mode threads.

  * Newlib

    * Fixed access fault when calling the newlib math functions from a user
      mode thread. All ``libm.a`` globals are now placed into the
      ``z_libc_partition`` when userspace is enabled.

* C++ Subsystem

  * Renamed all C++ source and header files to use the ``cpp`` and ``hpp``
    extensions, respectively. All Zephyr upstream C++ source and header files
    are now required to use these extensions.

* Management

  * MCUMGR has been migrated from using TinyCBOR, for CBOR encoding, to zcbor.
  * MCUMGR :kconfig:option:`CONFIG_FS_MGMT_UL_CHUNK_SIZE` and
    :kconfig:option:`CONFIG_IMG_MGMT_UL_CHUNK_SIZE` have been deprecated as,
    with the introduction of zcbor, it is no longer needed to use an intermediate
    buffer to copy data out of CBOR encoded buffer. The file/image chunk size
    is now limited by :kconfig:option:`CONFIG_MCUMGR_BUF_SIZE` minus all the
    other command required variables.
  * Added support for MCUMGR Parameters command, which can be used to obtain
    MCUMGR parameters; :kconfig:option:`CONFIG_OS_MGMT_MCUMGR_PARAMS` enables
    the command.
  * Added mcumgr fs handler for getting file status which returns file size;
    controlled with :kconfig:option:`CONFIG_FS_MGMT_FILE_STATUS`
  * Added mcumgr fs handler for getting file hash/checksum, with support for
    IEEE CRC32 and SHA256, the following Kconfig options have been added to
    control the addition:

    * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH` to enable the command;
    * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH_CHUNK_SIZE` that sets size
      of buffer (stack memory) used for calculation:

      * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_IEEE_CRC32` enables support for
        IEEE CRC32.
      * :kconfig:option:`CONFIG_FS_MGMT_HASH_SHA256` enables SHA256 hash support.
      * When hash/checksum query to mcumgr does not specify a type, then the order
        of preference (most priority) is CRC32 followed by SHA256.

  * Added mcumgr os hook to allow an application to accept or decline a reset
    request; :kconfig:option:`CONFIG_OS_MGMT_RESET_HOOK` enables the callback.
  * Added mcumgr fs hook to allow an application to accept or decline a file
    read/write request; :kconfig:option:`CONFIG_FS_MGMT_FILE_ACCESS_HOOK`
    enables the feature which then needs to be registered by the application.
  * Added supplied image header to mcumgr img upload callback parameter list
    which allows the application to inspect it to determine if it should be
    allowed or declined.
  * Made the ``img_mgmt_vercmp()`` function public to allow application-
    level comparison of image versions.
  * mcumgr will now only return ``MGMT_ERR_ENOMEM`` when it fails to allocate
    a memory buffer for request processing, when previously it would wrongly
    report this error when the SMP response failed to fit into a buffer;
    now when encoding of response fails ``MGMT_ERR_EMSGSIZE`` will be
    reported. This addresses issue :github:`44535`.
  * Added :kconfig:option:`CONFIG_IMG_MGMT_USE_HEAP_FOR_FLASH_IMG_CONTEXT` that
    allows user to select whether the heap will be used for flash image context,
    when heap pool is configured. Previously usage of heap has been implicit,
    with no control from a developer, causing issues reported by :github:`44214`.
    The default, implicit, behaviour has not been kept and the above
    Kconfig option needs to be selected to keep previous behaviour.


* SD Subsystem

  * Added the SD subsystem, which is used by the
    :ref:`disk access api <disk_access_api>` to interact with connected SD cards.
    This subsystem uses the :ref:`SDHC api <sdhc_api>` to interact with the SD
    host controller the SD device is connected to.

* Power management

  * Added :kconfig:option:`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC`.
    This option enables support for dynamically bind devices to a Power Domain. The
    memory required to dynamically bind devices is pre-allocated at build time and
    is based on the number of devices set in
    :kconfig:option:`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC_NUM`. The API introduced
    to use this feature are:

    * :c:func:`pm_device_power_domain_add()`
    * :c:func:`pm_device_power_domain_remove()`

  * The default policy was renamed from ``PM_POLICY_RESIDENCY`` to
    ``PM_POLICY_DEFAULT``, and ``PM_POLICY_APP`` was renamed to
    ``PM_POLICY_CUSTOM``.

  * The following functions were renamed:

    * :c:func:`pm_power_state_next_get()` is now :c:func:`pm_state_next_get()`
    * :c:func:`pm_power_state_force()` is now :c:func:`pm_state_force()`

  * Removed the deprecated function :c:func:`pm_device_state_set()`.

  * The state constraint APIs were moved (and renamed) to the policy
    API and accounts substates.

    * :c:func:`pm_constraint_get()` is now :c:func:`pm_policy_state_lock_is_active()`
    * :c:func:`pm_constraint_set()` is now :c:func:`pm_policy_state_lock_get()`
    * :c:func:`pm_constraint_release()` is now :c:func:`pm_policy_state_lock_put()`

  * Added a new API to set maximum latency requirements. The ``DEFAULT`` policy
    will account for latency when computing the next state.

    * :c:func:`pm_policy_latency_request_add()`
    * :c:func:`pm_policy_latency_request_update()`
    * :c:func:`pm_policy_latency_request_remove()`

  * The API to set a device initial state was changed to be usable independently of
    :kconfig:option:`CONFIG_PM_DEVICE_RUNTIME`.

    * :c:func:`pm_device_runtime_init_suspended()` is now :c:func:`pm_device_init_suspended()`
    * :c:func:`pm_device_runtime_init_off()` is now :c:func:`pm_device_init_off()`

* IPC

  * static_vrings: Fixed work queue (WQ) initialization
  * static_vrings: Introduced atomic helpers when accessing atomic_t variables
  * static_vrings: Moved to one WQ per instance
  * static_vrings: Added "zephyr,priority" property in the DT to set the WQ priority of the instance
  * static_vrings: Added configuration parameter to initialize shared memory to zero
  * Extended API with NOCOPY functions
  * static_vrings: Added support for NOCOPY operations
  * Introduced inter core messaging backend (icmsg) that relies on simple inter core messaging buffer

* Logging

  * Added UART frontend which supports binary dictionary logging.
  * Added support for MIPI SyS-T catalog messages.
  * Added cAVS HDA backend.

* Shell

  * Added API for creating subcommands from multiple files using memory section approach:

    * :c:macro:`SHELL_SUBCMD_SET_CREATE` for creating a subcommand set.
    * :c:macro:`SHELL_SUBCMD_COND_ADD` and :c:macro:`SHELL_SUBCMD_ADD` for adding subcommands
      to the set.

HALs
****

* Atmel

  * Added devicetree bindings, documentation, and scripts to support
    state-based pin control (``pinctrl``) API.
  * Imported new SoC header files for:

    * SAML21
    * SAMR34
    * SAMR35

* GigaDevice

  * Fixed GD32_REMAP_MSK macro
  * Fixed gd32f403z pc3 missing pincodes

* STM32:

  * Updated stm32f4 to new STM32cube version V1.27.0
  * Updated stm32f7 to new STM32cube version V1.16.2
  * Updated stm32g4 to new STM32cube version V1.5.0
