fb60aab245 drivers: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

e3621e6e00 drivers: serial: rcar: drop DEV_DATA/DEV_CFG usage
Stop using redundant DEV_DATA/DEV_CFG macros and use dev->data and
dev->config instead.
Follows #41918.

bff37a3a6c drivers: serial: remove @return doc for void functions
For functions returning nothing, there is no need to document
with @return, as Doxgen complains about "documented empty
return type of ...".

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.

54c481980e drivers: uart: Add "Interrupt driven" to R-Car
This commit add the support of "Interrupt driven UART"
to the R-Car UART driver and enable it in the related
Kconfig.

The driver is supporting nearly all the methods that are
described in the "Interrupt driven UART" part of the
uart_driver_api.

This new version of the driver has been tested on
H3ULCB board by running "uart_basic_api" test suite.

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.

Fixes #16231

c5a057bc63 drivers: serial: add Renesas R-Car driver
This patch add support for polling based UART
on the Renesas R-Car SCIF (Serial Communication Interface
with FIFO)

This hardware block can be found on various Renesas R-Car
SoC series.

It allows to get console on R-Car Gen3 H3ULCB board.
