e29a15c0e3 ITE: drivers/serial: add the UART driver for the PM callback function
IT8XXX2 uses shared ns16550.c driver which does not provide a power
management callback(pm_action_cb), so create driver to handle
IT8XXX2 specific UART features.

note: pm_action_cb(old name: pm_control_fn)

d9a3efb834 xenvm: drivers: serial: Implement serial interface to Xen PV console
This commit adds minimal support of Xen hypervisor console via UART-like
driver. Implementation allows to use poll_in/poll_out char interface for
uart_console.c driver directly to HV console instead of using Xen
virtual PL011 UART. Future implementation will support interrupt driven
interface on Xen event channels, currently it is under development.

Also this commit introduces early console_io Xen interface, which allows
to receive printk/stdout messages quickly after start, but requires Xen,
built with CONFIG_DEBUG option.

ad1450510a drivers: serial: Refactor drivers to use shared init priority Kconfig
Refactors all of the serial drivers to use a shared driver class
initialization priority configuration, CONFIG_SERIAL_INIT_PRIORITY, to
allow configuring serial drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.

The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The one
exception is uart_lpc11u6x.c which previously used
CONFIG_KERNEL_INIT_PRIORITY_OBJECTS.

This change was motivated by an issue on the frdm_k64f board where the
serial driver was incorrectly initialized before the clock control
driver.

ad19104f28 Microchip: MEC172x: Add UART driver
Microchip XEC has been using the standard NS16550 driver.
Using the standard NS16550 driver requires extra HW programming
for XEC UART in board level and did not support XEC GIRQ interrupt
programming. We add an XEC specific driver and remove UART specific
register programming from the board level and implement interrupt
support. Also, by implementing a SoC specific driver we can add

4e1692f85a serial: introduce CONFIG_UART_USE_RUNTIME_CONFIGURE
This kconfig option enables runtime configuration of UART
controllers. This allows application to call uart_configure()
to configure the UART controllers and calling uart_config_get()
to retrieve configuration. If this is disabled, UART controllers
rely on UART driver's initialization function to properly
configure the controller. The main use of this option is mainly
code size reduction.

7832738ae9 kernel/timeout: Make timeout arguments an opaque type
Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument.  Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created.  This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.

The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.

The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.

Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.

For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided.  When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.

Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions.  These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig.  These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.

k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.

Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate.  Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure.  But k_poll() does not fail
spuriously, so the loop was removed.

32d23cb3aa driver: api: uart: remove exclusive config for async api
The PR removes the exclusive limit on enabling both UART_ASYNC_API
and UART_INTERRUPT_DRIVEN so that both options can be enabled
together for same uart driver.

Also, the interrupt handler will be used for both cases. So, enable
definition of interrupt handler for both.

However, nRF UART driver still wants to enable only one of them.
So, a new config is added to disable the code for UART_ASYNC_API
when the option UART_INTERRUPT_DRIVEN is enabled.

116fb2fe0a kconfig: drivers: serial: Remove redundant dependencies
One of these is from 'source'ing a file within an 'if SERIAL', and then
adding another 'depends on SERIAL' within it.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.
