Since PINCTRL and pinctrl-0 is now required, there's no point in doing
extra validation at driver level. Modify the macro to just check that
sleep state is present when needed, since it was the only remaining
assertion that was not covered. Renamed the macro to make it more clear
what it does: NRF_DT_CHECK_NODE_HAS_PINCTRL_SLEEP

When checking if any UART TX/RX IRQs are pending, the driver should also
consider whether these IRQs are enabled. Or we still get pending status
set even if the related interrupts are disabled.

In order to avoid concurrency situation during writing UFTCTL register,
this CL adds critical sections to prevent the unexpected result if the

This patch is in preparation of uart async support. There are no
functional changes. The patch changes the ordering of functions to
organize shared functions between async/interrupt driven in the same order.
Also move uart_xmc4xxx_init() so that a forward declaration can be
removed.

In preparation for async support. In async uart, service requests are
forwarded to separate dma lines. This patch splits up tx/rx into
separate service requests to enable this.
Also put service request enable code into a separate function. Before,
the same code was generated for different uart devices.

Address map used for config item `uart_dev` and `uart_regs` is
currently derived using the rpi hal macros `uart0` and `uart1`
which map to the same register address as given in the `reg` property
of the devicetree.
However, the sdk macro is generated using `uart##idx` which zephyr does
not necessarily map to uart0 or uart1.
This is, for example, the case when disabling uart0 with the devicetree
status "disabled"
and enabling uart1 for which then the idx==0 and not 1 which therefore
maps to the wrong controller address space.
This can simply be fixed by deriving the base address from
`DT_INST_REG_ADDR(idx)` instead

Fix a bug that causes not handling an IDLE line detection interrupt for
some STM chips, e.g. STM32F412. It impacts the async UART
communication - an information that data have been recieved is lost.
The issue occurs when the IDLE flag is set during handling another UART
interrupt, e.g Transmission complete. The ISR calls uart_stm32_err_check
function, which clears the noise error flag with LL_USART_ClearFlag_NE
without any additional checks. Unfortunately, clearing the noise flag
also clears the IDLE flag for some chips(an read to the USART_SR
register followed by a read to the USART_DR register for STM32F412
clears PE, FE, NF, ORE and IDLE flags), hence the ISR is not called
again for the IDLE event. The IDLE flag is no longer set.
Add checking the noise flag before clearing it.

Fix the driver so that after a call to uart_rx_disable() it does not
allow re-enabling RX until the UART_RX_DISABLED is generated (what
means that the disabling procedure is complete). Otherwise, it is
possible that the RXTO event from the previous RX is handled right
after a new RX is started, and the RX buffer pointer gets corrupted
in the `rx_flush()` function.

Since the macro references `data->async->hw_rx_counting`, it cannot
be called when `data->async` is NULL, and this could happen when the
PM_DEVICE_ACTION_RESUME action was requested for an instance that uses
the interrupt-driven API while for another instance that uses the
asynchronous API the hardware counting of bytes was configured.
Prevent this by calling the macro from a proper `if` block.
