cd26742b17 doc: Edit microkernel_tasks.rst for grammar and clarity
Corrected a few typos and misspellings. Corrected grammar to add clarity to the
section on task groups.  Added cleaner headings to APIs to enhance readability.

cfed6d8286 doc : arduino_101 : add in udev rules
Currently we have several sections that require the use of sudo for
functionality, but that is a workaround to the need for libusb to
control the FlySwatter hardware.  This can be solved by adding in
proper udev rules.

06e2b4e129 nanokernel: Change fiber_delayed_start() return type
Instead of returning a 'void *', the nanokernel fiber_delayed_start()
family of routines now return a handle of type nano_thread_id_t.

    task_fiber_delayed_start()   task_fiber_delayed_start_cancel()

It is more intuitive for the end user to enable IPSP by
selecting the BT network driver which then automatically
enables relevant Bluetooth options. The earlier way
required user to select L2CAP dynamic channel support
first before he could activate IPSP and this is not very

ec678375a3 spi: dw: Quark SE Sensor Sub-System support
Though it's an ARC core, Quark SE SS does not follow the same registers
mapping as the official DesignWare document. Some parts are common, some
not.

Instead of bloating spi_dw.c with a lot of #ifdef or rewriting a whole
new driver though the logic is 99% the same, it's then better to:
 - centralize common macros and definitions into spi_dw.h
 - have a specific spi_dw_quark_se_ss_reg.h for register map, clock
   gating and register helpers dedicated to Quark SE SS.
 - have a spi_dw_regs.h for the common case, i.e. not Quark SE SS.

GPIO CS emulation and interrupt masking ends up then in spi_dw.h.
Clock gating is specific thus found in respective *_regs.h header.

Adding proper interrupt masks to quark_se_ss soc.h file as well.

One of the main difference is also the interrupt management: through one
line or multiple lines (one for each interrupt: rx, tx and error). On
Quark SE Sensor Sub-System it has been set to use multiple lines, thus
introducing relevant Kconfig options and managing those when configuring
the IRQs.

Quark SE SS SPI controller is also working on a lower level, i.e. it
requires a tiny bit more logic from the driver. Main example is the data
register which needs to be told what is happening from the driver.

Taking the opportunity to fix minor logic issues:
- ICR register should be cleared by reading, only on error in the ISR
  handler, but it does not harm doing it anyway and because Quark SE SS
  requires to clear up interrupt as soon as they have been handled,
  introducing a clear_interrupts() function called at the and of the ISR
  handler.
- TXFTLR should be set after each spi_transceive() since last pull_data
  might set it to 0.
- Enable the clock (i.e. open the clock gate) at initialization.
- No need to mask interrupts at spi_configure() since these are already
  masked at initialization and at the end of a transaction.
- Let's use BIT() macro when relevant.

424cd841e2 spi: Enable QMSI driver for Quark D2000
This patch fixes the QMSI SPI shim driver so we are able to use it in
Quark D2000 based platforms. The only change required to enable this
driver is an #if guard in spi_qmsi_init() because the macro QM_SPI_MST_1
and the function qm_spi_master_1_isr are not defined in QMSI headers
from Quark D2000.

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.

f5a360e1fb samples: rtc: Remove driver selection
This patches removes 'CONFIG_RTC_DW=y' so we rely on the platform's
default option for the RTC driver. This way the RTC sample application
can be built for different platforms without changing the configuration
file.

6b23dc40d1 watchdog: Set DW driver as default for Quark SE and D2000
This patch changes both Quark SE and D2000 Kconfig files to enable the
WDT_DW driver by default if the WATCHDOG is enabled. This way, we keep
it consistent with the approach we already follow for others peripheral
drivers (GPIO, I2C, SPI).

ec7c6a80fc i2c: Enable QMSI driver for Quark D2000
This patch fixes the QMSI I2C shim driver so we are able to use it in
Quark D2000 based platforms. The only change required to enable this
driver is an #if guard in i2c_qmsi_init() because the macro QM_I2C_1
is not defined in QMSI headers from Quark D2000.

Since this drivers is now properly tested with Quark D2000, this patch
sets the QMSI driver default options in arch/x86/soc/quark_d2000/Kconfig.
It also adds the wiring information required to test the i2c_lsm9ds0
sample app in the Quark D2000 CRB.

fa1e56520b qmsi: Enable both I2C controllers by default
In case the I2C_QMSI driver is selected by the user, enable both I2C
contollers by default. This is the default behavior for I2C_DW driver
as well.

0c5b7f7d22 samples: Add i2c_lsm9ds0 application
This patch adds a new sample application to demonstrate how to use
I2C APIs. The application is very simple. It simply reads the 'WHO
AM I' register from the accelerometer in the LSM9DS0 chip and check
if it matches with the value described in the datasheet.

It also adds a README file which provides the wiring information
required to get the sample application working on Quark SE DevBoard.
