ace49af6b0 uart: Enable QMSI driver for Quark D2000
This patch fixes the QMSI UART shim driver so we are able to use it in
Quark D2000 based platforms. Differently from Quark SE, the peripheral
clock gate bit (CLK_PERIPH_CLK) is not enabled by default in Quark
D2000. We have to explicitly set this bit in order to properly initialize
the device.

Since this drivers is now properly working on Quark D2000, this patch
also sets the QMSI driver default options in arch/x86/soc/quark_d2000/
Kconfig.

3172fca3a0 drivers: qmsi: Fix gpio, i2c and wdt for D2000
This patch fixes the gpio, i2c and watchdog shim drivers so they set the
CLK_PERIPH_CLK bit during driver initialization. Differently from Quark
SE, the peripheral clock gate bit (CLK_PERIPH_CLK) is not enabled by
default in Quark D2000. We have to explicitly set this bit in order to
properly initialize the device.

This issue has been masked so far because the CLK_PERIPH_CLK bit is set
when UART NS16550 driver is enabled. The UART NS16550 driver is enabled
by default for Quark D2000 so gpio, i2c and watchdog sample apps were
working just fine. But if we disable the NS16550 driver, these samples
applications stop working.

The remaining shim drivers already set the CLK_PERIPH_CLK bit during
initialization so there is no need to fix them.

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.

6461e70b72 gpio/stm32: add common driver for STM32 GPIO
The driver implements a GPIO device interface for STM32 MCUs. Each SoC
must provide implementation of the follwoing calls:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(),
stm32_gpio_set(). Consult gpio_stm32.h header for details on semantics
of these calls.

The driver registers 5 devices, each corresponding to a single GPIO
port. The users can then access individual pins by using values
0-15.

e53390f02d pinmux/stm32: add common driver for STM32 pinmux
Add a common driver for pin control subsystem in STM32 MCU series. The
driver allows for selection of pin's function without the ability of pin
remapping.

The driver implements a pinmux driver API, with custom `func` and `pin`
encoding in API calls. The caller is expected to use STM32PIN() helper
macro for encoding port/pin numbers or using one of the provided
STM32_PIN_* defines.

The common driver requires SoC specific support to be implemented. The
SoC code must implement these calls: stm32_get_pin_config(),
stm32_get_port_clock(), stm32_pin_configure(). Consult pinmux_stm32.h
header for detailn on semantics of these calls.

The driver also requires board level integration. The call
stm32_board_get_pinconf() is expected to privide pin function
assignments for the target board.

Whenever an IO pin is being enabled, the driver will automatically
enable the clock for corresponding port. The driver does not implement
disabling of port's clock as this has potentially disruptive, as such
such operation should be done explicitly in the code.

The pin control module needs to be initialized before any other modules,
but after clock_control. For this reason, the driver is initialized by
default at PRIMARY level, with priority set to 2. The priority can be
changed through configuration.

This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

024cfe754e drivers: Replace DEV_OK by 0
This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

5f1988f284 pinmux: Change returning type from pinmux.h APIs
All driver APIs (i2c, spi, gpio, etc.) return 'int' type, but pinmux
APIs. So this patch changes the returning type from 'uint32_t' to
'int' from include/pinmux.h and fixes all pinmux drivers according.

Besides keeping consistency between all drivers APIs, this patch is
also applicable for the errno.h code transition. Pinmux drivers will
return negative errno.h codes so returning 'int' is more suitable
than 'uint32_t'.

3f5af00529 clock_control/stm32f10x: introduce driver for STM32F10x RCC
The patch adds a driver for STM32F10x series RCC (Reset and Clock
Control) subsystem.

The module is primarily responsible for setting up of MCU's clock
tree. In particular the driver sets up SYSCLK, PLL (with source
configuration), AHB prescaler, and APB1/APB2 prescalers. As part of this
functionality, the subsystem can enable/disable clock signal for
particular peripherals, thus reducing the power consumption of the MCU.

The driver implements clock control driver API. However, subsystem IDs
being HW specific are exposed in driver public header that must be
included by callers. The driver registers a single device using a common
name STM32_CLOCK_CONTROL_NAME. The device is initialized at
the PRIMARY level with priority 1. This allows the initialization to
take place right after SoC initialization routine.

The driver depends on selection of SOC_STM32F1X config option and is MCU
specific.

14482f0940 clock_control: extend API with clock rate query operation
Extend the public API of clock_control driver with a function for
querying of clock rate driving given peripheral. This is useful when the
driver must calculate or configurae values that depend on the rate of
clock driving this subsystem.

A baud rate setting of UART port is an example of such operation. To
configure a particular baud rate the driver may need to set the internal
counters of UART port, where the actual value will depend on the clock
rate for this peripheral.

The implementation returns DEV_NO_SUPPORT for clock_control drivers that
do not implement such functionality.
