* STM32 ADC driver now supports mixing shared and separate IRQs (for instance on STM32G473
which has 5 ADCs, ADC1 and ADC2 share one IRQ while ADC3, ADC4 and ADC5 each have unique IRQs).
Enabling all instances in same application is not possible on such devices as of now.

* Serial

* Added drivers to support UART on Renesas RA and RZ/T2M.

* Added support for higher baud rate for ITE IT8xxx2.

* Added driver to support Intel Lightweight UART.

* Added UART asynchronous RX helper.

* Added support for async API on NS16550 driver.

* Updated ``uart_esp32`` to use serial port configuration from devicetree.

* Added an adaptation API to provide interrupt driven API for drivers
which have only implemented async API.

* Emulated UART driver (:file:`drivers/serial/uart_emul.c`):

* Added emulated interrupt based TX.

* Added emulated error for testing.

* Modified to use local work queue for data transfer.

* Modified FIFO size and its handling to be more aligned with real hardware.
* On STM32 devices, it is now possible to enable FIFO by setting a ``fifo-enable``
property in targeted serial node, with the following benefits:
In TX, FIFO allows to work in burst mode, easing scheduling of loaded applications.
It also allows more reliable communication with UART devices sensitive to variation of inter-frames delays.
In RX, FIFO reduces overrun occurences.

* SPI

* On STM32H7 devices, ``fifo-enable`` property allows using SPI block FIFO. This
feature is still experimental and requires maturation.
* On STM32 devices impacted by BSY bit erratum, a workaround is implemented.

* Timer

* USB

* On STM2G0 devices, property ``crs-usb-sof`` in ``clk_hsi48`` node enables support
for Clock Recovery System allowing a more stable HSI48 clock and hence resilient USB
connection.
* On compatible STM32 devices, isochronous endpoint are now functional thanks to the
use of double buffering.

* Wi-Fi

* Added Infineon airoc driver.
