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'.

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.

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.

Sensor drivers expose one or more channels, corresponding to each
individual quantity they can measure. Such quantities may be different
altogether (e.g. temperature and pressure) or different axes for the
same unit (e.g. three axes of acceleration). Before reading channels, a
driver must be explicitly instructed to obtain a sample from the device.
This helps accommodate sensors which can only read all channels at once,
and also helps ensure coherence of measurements and optimize I2C/SPI
traffic.
Channels can be read as floating point values or struct sensor_value.
The latter consists of a pair of integers and a type field which
dictates how to interpret said integers. The most common type is INT
(where the second value is ignored) or INT_PLUS_MICRO, which means the
second value should be multiplied by 1.0e-6 and added to the first.
A sensor driver may support one or more triggers, corresponding to
interrupts or timers. Registering for a trigger involves supplying the
driver with a callback which is called when a condition is reached.
Examples of trigger types are: data ready, timer expiration, any-motion,
near/far.
Finally, sensors support attributes such as sample frequency,
measurement accuracy or threshold values for triggers. However, runtime
configuration is discouraged, in the interest of keeping code simple.

Microkernel timers are defined at compile time as a static list
but they are allocated dynamically in kernel execution.
The object tracing list will only list those timers that are
currently allocated at debug time. For this reason, timers
can be removed from the tracing list at any time.
A very simple double linked list was implemented to reduce the
complexity of the action to remove an item from the list from O(n)
to O(1) and simplify the remove implementation.

Support for Freescale/NXP K64 SPI modules, limited to:
- Master mode
- A single active set of clock and transfer attributes (CTAR0), which
includes non-adjustable delay parameters
- Tx FIFO fill and Rx FIFO drain interrupt handling
- Standard, continuous select and continuous SCK SPI transfer formats
Also, divide-by-zero code generation in this driver is prevented.
The 'volatile' attribute is added to some of the variables in the baud
rate and delay calculation functions of the K64 SPI driver in order to
prevent bad code generation by gcc toolchains for ARM seen when an
optimization setting above -O0 is used.
Specifically, a register is loaded with the constant 0 and is used as
the divisor in a following divide instruction, resulting in a
divide-by-zero exception.
This issue has been seen with gcc versions 4.8.1 (the VxWorks toolchain)
and 5.2.0 (the Zephyr SDK toolchain).

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

unnecessary typecasts aren't needed for that either (if the data

formally defined, instead it was defined separately for each arch
in their respective arch-specific header files. Occasionally these

Now there is a single irq.h header which defines this interface.

each that must be defined in headers pulled in by arch/cpu.h.
