The old CONFIG_UART_NS16550_ACCESS_IOPORT has been used to
indicate whether to access the NS16550 UART via IO port
before device tree is used to describe hardware. Now we have
device tree, and we can specify whether a particular UART
needs to be accessed via IO port using property io-mapped.
Therefore, CONFIG_UART_NS16550_ACCESS_IOPORT is no longer
needed (and thus also CONFIG_UART_NS16550_SIMULT_ACCESS).
Remove these two kconfigs and modify code to use device tree
to figure out how to access the UART hardware.

Dom0less is Xen mode without privileged domain. All guests are created
according to hypervisor device tree configuration on boot. Thus, there
is no Dom0 with console daemon, that usually manages console output
from domains.
Zephyr OS contains 2 serial drivers related to Xen hypervisor: regular
with console shared page and consoleio-based. The first one is for
setups with console daemon and usually was used for Zephyr DomU guests.
The second one previously was used only for Zephyr Dom0 and had
corresponding Kconfig options. But consoleio is also used as interface
for DomU output on Dom0less setups and should be configurable without
XEN_DOM0 option.
Add corresponding XEN_DOM0LESS config to Xen Kconfig files and proper
dependencies in serial drivers.

Per the SAMD5x/E5x Datasheet Sect. 34.8.6, writing '1' to the TXC will

preserved through the irq_update for use in the tx_complete check function
The proper fix will cache the TXC value before conditionally clearing the

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Fixes a race condition between uart_xmc4xxx_dma_rx_cb() and rx timeout.
Although uart_xmc4xxx_dma_rx_cb() called k_work_cancel_delayable()
to cancel the timeout callback, it would not actually be cancelled if
the callback was already in a running state.
Fix the race condition by checking if dma transaction is already
completed in the timeout callback.
This also fixes unit test tests/drivers/uart/uart_async_api on
xmc45_relax_kit which started to fail after commit
f3afd5a4c9.

This effectively reverts the following three commits:
- 0f9f18843f
- 6812441099
- 326f7bd450
and also the changes that got copied to the nrf5340_audio_dk_nrf5340
board.
The workaround brings more harm than good. It already required many
tweaks in various tests to make them pass (because it introduced
a significant overhead in processing of the console UART interrupt)
and now it makes the I2S driver tests to fail. It's not reasonable
to add more tweaks in Zephyr tests just to keep this workaround in
the tree. Instead the root cause should be fixed (if the original
problem still occurs).

Enabled simultaneous support by adding a DTS variable named “io-mapped”.
There are 3 possibilities through instance in dtsi file.
Under PCIe, PCIe ns16550.
Under soc and has a variable io-mapped, legacy(IO mapped).
Under soc and don’t have a variable io-mapped, MMIO mapped.
Simultaneous access can be enabled by a Kconfig.
For PCIe instances UART initialization should be done post-kernel as it
depends on PCIe initialization.

Add clock control support for UART controllers found in i.MX SoC family.
This change moves clock gating out of respective `soc.c` files and into
clock controller's `clock_control_on`/`_off` methods, allowing for
dynamic clock state control, and setup via Device Tree bindings.
This is especially important on SoCs, where Zephyr is sharing the bus
with cores running other OSes, such as might be the case for i.MX 8MM.
Unfortunately, Zephyr doesn't possess an ability to represent clock
hierarchy (e.g. via DT's `assigned-clocks` property), so clock source
and frequency still need to be hardcoded in aforementioned `soc.c`
files.

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.

after a new RX is started, and the RX buffer pointer gets corrupted

Since the macro references `data->async->hw_rx_counting`, it cannot
be called when `data->async` is NULL, and this could happen when the

asynchronous API the hardware counting of bytes was configured.
