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.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

86c46864ee drivers: ethernet: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

e290006144 serial: Introduce new mcux lpuart shim driver
Adds a shim layer around the mcux lpuart driver to adapt it to the Zephyr
serial interface.

NXP has multiple uart hardware blocks that implement different features
and have different register maps. The k64 has a uart block called
'uart', while the kw41 has a uart block called 'lpuart' (low power
uart). The MCUXpresso SDK provides separate drivers for each type of
uart block but with similar software interfaces. As a result, there are
also separate shim drivers in Zephyr. There is a 1:1:1 relationship
between hardware block, mcux driver, and mcux shim driver.

Because we now have two mcux shim drivers for the uart interface, a new
naming convention is created:

	<interface>_mcux_<hw block>

Where <interface> is the name of the Zephyr interface, in this case
'uart'. This convention is not new.

<hw block> is the name of the NXP hardware block, in this case 'lpuart'.
This is the new part, and distinguishes different hardware blocks
for the same interface.

7633279d4a uart: qmsi: Add support for IRQ APIs
This patch extends the UART QMSI driver so it supports the IRQ APIs from
include/uart.h. The IRQ APIs are enabled by the 'CONFIG_UART_INTERRUPT_
DRIVEN' option.

Differently from others APIs such as I2C and SPI, the UART API is very
low level. For that reason, the IRQ facilities (e.g. irq based transfers)
from the QMSI driver are not useful to the shim driver at the moment. In
order to implement the IRQ APIs we rely on UART registers defined by QMSI.
QMSI UART header is missing some macro definitions from IRR register so
we define them in the shim driver.

Since the IRQ trigger condition is not configurable in the QMSI shim
driver, this patch also changes drivers/serial/Kconfig so the "UART
IRQ Trigger Condition" choice doesn't appear on the menu if the QMSI
driver is selected.

d95d6c63a1 uart: Introduce QMSI shim driver
This patch introduces the QMSI UART driver which is simply a shim driver
based on UART driver provided by QMSI BSP.

This initial version implements only the mandatory APIs 'poll_in',
'poll_out' and 'err_check' which are required by trivial sample apps and
by output functionality from the console driver. The remaining APIs will
be implemented by up coming patches. The driver supports only 115200 baud
rate at the moment.

In order to enable this driver, the following options should be set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_SERIAL=y
CONFIG_UART_QMSI=y

This driver has been tested with Quark SE Devboard so this patch also
adds its platform-specific default configuration options to 'arch/x86/
soc/quark_se/Kconfig'.

() Adds (many) Kconfig options. These don't have to be defined
   in each platform's board.h anymore.

d77f6efe03 serial/k20: refactor (again) to conform to driver model
() Rename k20UartDrv.c to uart_k20.c. This is to follow the driver
   naming convention.
() Move driver/serial/k20_uart.h to drivers/serial/uart_k20_priv.h
   as this contains definitions private to the driver, and
   should not be exposed in public include directory.
() Rename functions k20_uart_*() to uart_k20_*(), following
   driver naming convention.
() Renames CONFIG_K20_UART_* to CONFIG_UART_K20_*
() UART ports initialization is moved into the driver itself.
