This function is only checking for current byte being transmitted.
This patch ensures that function returns `1` until TX is disabled and
no byte is being transmitted.

Remove address-of operator ('&') when assigning `init_fn`
function pointer in `DEVICE_DT_INST_DEFINE` macro.
This change aims to maintain consistency among the drivers in
`drivers/serial`, ensuring that all function pointer assignments
follow the same pattern.

Implementation of PM in the driver requires PM to be enabled. This was
enabled in the SoC until now and was recently removed.

Fix a build error when the driver is built with:
CONFIG_PM=y
CONFIG_PM_DEVICE=n
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_UART_CONSOLE_INPUT_EXPIRED=y
due to uart_xec_pm_policy_state_lock_get() and rx_refresh_timeout_work()
declared under different configuration options.

changes to support low power and wake support in microchip xec uart
driver. Add support for wakerx_gpio config in dts to select the wake gpio.
Configure for wake in PM_DEVICE_ACTION_SUSPEND state and clear
interrupt in wake isr. Also added support for
CONFIG_UART_CONSOLE_INPUT_EXPIRED

Change automated searching for files using "IRQ_CONNECT()" API not
including <zephyr/irq.h>.

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.

Stop using redundant DEV_DATA/DEV_CFG macros and use dev->data and

For functions returning nothing, there is no need to document
with @return, as Doxgen complains about "documented empty
return type of ...".

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.

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
driver PM in the future.
