Gil Pitney e8b43cbc81 cc3200: Add a UART driver (polled and interrupt modes)
The pinmux configuration is done during board initialization.

This was validated using the following Zephyr apps:
- samples/hello_world
- samples/philosophers
- samples/drivers/uart
- samples/shell

UARTA0 is currently supported.

Daniel Leung 8f6068e9d8 serial/ns16550: make IRQ triggering condition a SoC decision
The IRQ triggering condition should be specified by SoC as it is
a decision for hardware design. This should not be configurable
in kconfig.

The default is to be triggered on rising edge, just as the same
old kconfig did.

Maciek Borzecki 5a73ca6809 serial/stm32: add driver for STM32 UART
Add driver for U(S)ART ports on STM32 MCUs. The driver implements basic
RX/TX functionality. Data transmission is implemented using polling. The
driver configures the port to use 8bit data transmission, 1 stop bit, no
parity control.

The driver exposes a public uart driver API and registers a single UART
device 'UART_0'. The device binds to USART1 peripheral and performs
required pinmux and clock control configuration. The device can be
initialized at the PRIMARY level, with default device priority.

The driver has been verified to work with a sample Hello World
application on a STM32F103 series MCU.

Andre Guedes 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.

Andre Guedes 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'.

Daniel Leung 21c3118655 serial: adds UART driver for SAM3X8E
This adds driver for the UART controller on Atmel SAM3X8E.
This UART controller only has two wires for RX and TX, and
does not have flow control (e.g. CTS, RTS) or FIFO.

Currently, the driver does not support any interrupt driven
operations.

Daniel Leung 64cba6d9c7 serial/uart: adds new APIs for serial line control
This adds 2 new APIs to the serial/uart drivers:
() One is to control the serial line, such as RTS and CTS.
() Another one is to allow driver to expose hardware specific functions
   to apps. This is needed as some hardware may have extra registers to
   set for baud rate.

To keep the code size small, these features are disabled by default.

Daniel Leung 1d816afcc0 serial: remove unused code after refactoring
Remove unused code after refactoring all the serial/UART drivers.

() Since device initialization is done by the drivers themselves,
   there is no need to have config_func(), port_init() and uart_init()
   to perform configuration external to driver. So remove the related
   bits.
() The IRQ priority is only being used when doing IRQ_CONNECT_STATIC().
   So there is no need to send it over during uart_init().
