API Changes
***********
Changes in this release
=======================
* Following functions in UART Asynchronous API are using microseconds to represent
timeout instead of milliseconds:
* :c:func:`uart_tx`
* :c:func:`uart_rx_enable`
* Replaced custom LwM2M :c:struct:`float32_value` type with a native double type.
* Added function for getting status of USB device remote wakeup feature.
* Added ``ranges`` and ``dma-ranges`` as invalid property to be used with DT_PROP_LEN()
along ``reg`` and ``interrupts``.
* The existing :c:func:`crc16` and :c:func:`crc16_ansi` functions have been
modified. The former has a new signature. The latter now properly calculates the
CRC-16-ANSI checksum. A new function, :c:func:`crc16_reflect`, has been
introduced to calculated reflected CRCs.
* GATT callbacks ``bt_gatt_..._func_t`` would previously be called with argument
``conn = NULL`` in the event of a disconnect. This was not documented as part
of the API. This behavior is changed so the ``conn`` argument is provided as
normal when a disconnect occurs.
Removed APIs in this release
============================
* The following Kconfig options related to radio front-end modules (FEMs) were
removed:
* ``CONFIG_BT_CTLR_GPIO_PA``
* ``CONFIG_BT_CTLR_GPIO_PA_PIN``
* ``CONFIG_BT_CTLR_GPIO_PA_POL_INV``
* ``CONFIG_BT_CTLR_GPIO_PA_OFFSET``
* ``CONFIG_BT_CTLR_GPIO_LNA``
* ``CONFIG_BT_CTLR_GPIO_LNA_PIN``
* ``CONFIG_BT_CTLR_GPIO_LNA_POL_INV``
* ``CONFIG_BT_CTLR_GPIO_LNA_OFFSET``
* ``CONFIG_BT_CTLR_FEM_NRF21540``
* ``CONFIG_BT_CTLR_GPIO_PDN_PIN``
* ``CONFIG_BT_CTLR_GPIO_PDN_POL_INV``
* ``CONFIG_BT_CTLR_GPIO_CSN_PIN``
* ``CONFIG_BT_CTLR_GPIO_CSN_POL_INV``
* ``CONFIG_BT_CTLR_GPIO_PDN_CSN_OFFSET``
This FEM configuration is hardware description, and was therefore moved to
:ref:`devicetree <dt-guide>`. See the :dtcompatible:`nordic,nrf-radio`
devicetree binding's ``fem`` property for information on what to do instead
on the Nordic open source controller.
* Removed Kconfig option ``CONFIG_USB_UART_CONSOLE``.
Option ``CONFIG_USB_UART_CONSOLE`` was only relevant for console driver
when CDC ACM UART is used as backend. Since the behavior of the CDC ACM UART
is changed so that it more closely mimics the real UART controller,
option is no longer necessary.
* Removed Kconfig option ``CONFIG_OPENOCD_SUPPORT`` in favor of
``CONFIG_DEBUG_THREAD_INFO``.
* Removed ``flash_write_protection_set()`` along with the flash write protection
implementation handler.
* Removed ``CAN_BUS_UNKNOWN`` and changed the signature of
:c:func:`can_get_state` to return an error code instead.
* Removed ``DT_CHOSEN_ZEPHYR_CANBUS_LABEL`` in favor of utilizing
:c:macro:`DEVICE_DT_GET`.
* Removed ``CONFIG_LOG_MINIMAL``. Use ``CONFIG_LOG_MODE_MINIMAL`` instead.
* STM32 clock_control driver configuration was moved from Kconfig to :ref:`devicetree <dt-guide>`.
See the :dtcompatible:`st,stm32-rcc` devicetree binding for more information.
As a consequence, following Kconfig symbols were removed:
* ``CONFIG_CLOCK_STM32_SYSCLK_SRC_HSE``
* ``CONFIG_CLOCK_STM32_SYSCLK_SRC_HSI``

* ``CONFIG_CLOCK_STM32_PLL_SRC_MSI``
* ``CONFIG_CLOCK_STM32_PLL_SRC_HSI``
* ``CONFIG_CLOCK_STM32_PLL_SRC_HSE``
* ``CONFIG_CLOCK_STM32_PLL_SRC_PLL2``
* ``CONFIG_CLOCK_STM32_PLL_SRC_CSI``
* ``CONFIG_CLOCK_STM32_AHB_PRESCALER``
* ``CONFIG_CLOCK_STM32_APB1_PRESCALER``
* ``CONFIG_CLOCK_STM32_APB2_PRESCALER``
* ``CONFIG_CLOCK_STM32_CPU1_PRESCALER``
* ``CONFIG_CLOCK_STM32_CPU2_PRESCALER``
* ``CONFIG_CLOCK_STM32_AHB3_PRESCALER``

Instead, use :dtcompatible:`ti,ina230` or :dtcompatible:`ti,ina237`.
* West (extensions)
* Added support for gd32isp runner
Libraries / Subsystems
**********************
* Management
* Fixed the mcumgr SMP protocol over serial not adding the length of the CRC16 to packet length.
* Kconfig option OS_MGMT_TASKSTAT is now disabled by default.
* Power management
* Power management resources are now manually allocated by devices using
:c:macro:`PM_DEVICE_DEFINE`, :c:macro:`PM_DEVICE_DT_DEFINE` or
:c:macro:`PM_DEVICE_DT_INST_DEFINE`. Device instantiation macros take now
a reference to the allocated resources. The reference can be obtained using
:c:macro:`PM_DEVICE_GET`, :c:macro:`PM_DEVICE_DT_GET` or
:c:macro:`PM_DEVICE_DT_INST_GET`. Thanks to this change, devices not
implementing support for device power management will not use unnecessary
memory.
* Device runtime power management API error handling has been simplified.
* :c:func:`pm_device_runtime_enable` suspends the target device if not already
suspended. This change makes sure device state is always kept in a
consistent state.
* Improved PM states Devicetree macros naming
* Added a new API call :c:func:`pm_state_cpu_get_all` to obtain information
about CPU power states.
* ``pm/device.h`` is no longer included by ``device.h``, since the device API
no longer depends on the PM API.
* Added support for power domains. Power domains are implemented as
simple devices and use the existent PM API for resume and suspend, devices
under a power domain are notified when it becomes active or suspended.
* Added a new action :c:enum:`PM_DEVICE_ACTION_TURN_ON`. This action
is used by power domains to notify devices when it becomes active.
* Added new API (:c:func:`pm_device_state_lock`,
:c:func:`pm_device_state_unlock` and
:c:func:`pm_device_state_is_locked`) to lock a device pm
state. When the device has its state locked, the kernel will no
longer suspend and resume devices when the system goes to sleep
and device runtime power management operations will fail.
* :c:func:`pm_device_state_set` is deprecated in favor of utilizing
:c:func:`pm_device_action_run`.
* Proper multicore support. Devices are suspended only when the last
active CPU. A cpu parameter was added to Policy and SoC interfaces.
* Tracing
* Support all syscalls being traced using the python syscall generator to
introduce a tracing hook call.
* IPC
* Added IPC service support and RPMsg with static VRINGs backend
HALs
****
* STM32
* stm32cube/stm32wb and its lib: Upgraded to version V1.12.1
* stm32cube/stm32mp1: Upgraded to version V1.5.0
* stm32cube/stm32u5: Upgraded to version V1.0.2
* Added `GigaDevice HAL module
<https://github.com/zephyrproject-rtos/hal_gigadevice>`_
MCUboot
*******
* Fixed serial recovery skipping on nrf5340.
* Fixed issue which caused that progressive's erase feature was off although was
selected by Kconfig (introduced by #42c985cead).
* Added check of reset address in incoming image validation phase, see
``CONFIG_MCUBOOT_VERIFY_IMG_ADDRESS``.
* Allow image header bigger than 1 KB for encrypted images.
* Support Mbed TLS 3.0.
* stm32: watchdog support.
* many documentation improvements.
* Fixed deadlock on cryptolib selectors in Kconfig.
* Fixed support for single application slot with serial recovery.
* Added various hooks to be able to change how image data is accessed, see
``CONFIG_BOOT_IMAGE_ACCESS_HOOKS``.
* Added custom commands support in serial recovery (PERUSER_MGMT_GROUP): storage
erase ``CONFIG_BOOT_MGMT_CUSTOM_STORAGE_ERASE``, custom image status
``CONFIG_BOOT_MGMT_CUSTOM_IMG_LIST``.
* Added support for direct image upload, see
``CONFIG_MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD`` in serial recovery.
Trusted Firmware-m
******************
* Updated TF-M to 1.5.0 release, with a handful of additional cherry-picked
commits.
Documentation
*************
* A new theme is used by the Doxygen HTML pages. It is based on
`doxygen-awesome-css <https://github.com/jothepro/doxygen-awesome-css>`_
theme.
Tests and Samples
*****************
* Drivers: clock_control: Added test suite for stm32 (u5, h7).
