Andre Guedes 93831ebcce i2c: Fix i2c_qmsi_configure()
In the initial version of the I2C shim driver, the i2c clock gate was

to move it to i2c_qmsi_init() but missed to remove the clk_periph_disable
call within i2c_qmsi_configure(). So this patch removes it.

Tomasz Bursztyka 930bb9d3ca cc2520: Make the driver more in line with Zephyr
CC2520 drivers as a singleton:
Current driver can only handle a single instance. This is due to the
gpio callback which cannot provide the concerned device (not the gpio
device, the cc2520 one). Setting a singleton instance for now, as the
network stack cannot handle more net devices anyway. This will be fixed
in the future.
In the mean time: improving a bit the usage of spi and gpio by accessing
the cc2520 instance directly.

Also: simplifying SPI usage, useless internal locking removed, better
debugging routines, better busy wait macro and use Zephyr's BIT() macro
instead of internal one.

Writing: If nothing will be transmitted anymore, downsizing the level to

Busy flag bit in the ISR handler. As the threshold level makes more
sense, kepping this one.

Jesus Sanchez-Palencia 6504b7e72a gpio: Add QMSI-based implementation
Introduce the GPIO QMSI-based implementation. This is basically a
shim layer that implement's Zephyr's GPIO APIs on top of QMSI drivers.

This is an alternative driver that conflicts with the previous
GPIO_DW implementation. In order to enable it you must set:
- CONFIG_GPIO=n
- CONFIG_GPIO_QMSI=y
- CONFIG_GPIO_0=y
- CONFIG_QMSI_DRIVERS=y
- CONFIG_QMSI_INTALL_PATH="PATH_TO_QMSI"

Note that this driver currently only supports one controller instance,
GPIO_0. It is implemented this way due to a limitation from the current
version of QMSI. QMSI versions later than 1.0 doesn't have this
limitation.

Missing:
- support multiple controller instances (gpio_0, gpio_1, etc);
- enable level triggered interrupts in sync with system clock,
through setting INT_CLOCK_SYNC properly.

Juan Manuel Cruz 41771e5b1c adc: Repetitive buffer management
This commit changes the behavior of the driver when it reports
buffer results back through the callback.

Originally, the driver reported a callback after each sequence
table round signaled by an interrupt. If in repetitive mode,
each reported result was put in the next buffer element,
which was considered circular, and reported back with callback.

Now the behavior changes. If in repetitive mode, each sequence table
round reported by an interruption puts the data  in next element of
the reception buffer. The callback reports back once the buffer is
fulled and stops the sampling process.

Andre Guedes 959632684c i2c: Introduce QMSI I2C driver
This patch introduces the QMSI I2C driver which is simply a shim driver
based on I2C driver provided by QMSI BSP.

This initial version supports only I2C_0 controller in 'master' mode.
Due to some issues with qm_i2c_master_irq_transfer API, the driver uses
the polling APIs from QMSI. This means that the current thread doesn't
sleep (i.e. is not scheduled out) while the I2C transfer is carried out.
The qm_i2c_master_irq_transfer() issue is under investigation.

Below follows the missing features which will be addressed by a new
version of this patch or by upcoming patches.
  * Block the current thread until the I2C operation has actually
    completed.
  * Add support for multiple controllers.
  * Add support for slave mode.
  * Add support for suspend() and resume() APIs.

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_I2C=y
CONFIG_I2C_QMSI=y

Finally, due to the lack of proper support for Quark SE in QMSI 1.0.0,
this driver requires QMSI version greater than 1.0.0.

This driver has been tested only with Quark SE based boards.
