Andrew Boie 0b474eef9c kernel: deprecate old init levels
PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Iván Briano 0094ab228d ext qmsi: Update to QMSI 1.3 release
Update the QMSI drop we maintain in Zephyr, and fix the build where
needed:

- QM_SCSS_INT is renamed to QM_INTERRUPT_ROUTER;
- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

In order to restore i2c context after entering
SYS_PM_DEEP_SLEEP, suspend and resume functions
are called.

The following parameters are restored:
 - All registers for the I2C device.
 - I2C clocks.

I2C depends on the DMA which is enabled separately.

The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

Andre Guedes 6e71586c37 i2c: qmsi: Add support for default configuration
This patch extends the i2c shim driver so it supports the 'default
configuration' infrastructure which enables the user to specify a
default configuration for the I2C device. The default configuration
is set during driver initialization.

This patch also changes Quark SE and D2000 Kconfig.defconfig files so
the i2c default configuration is set to '0x12' which means standard
bus speed, 7-bit addressing and master mode. This is the same value
used when DW driver is selected, by the way.

Andre Guedes 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.

Andre Guedes 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.

Andre Guedes dacf54de68 i2c: Enable interrupts for QMSI shim driver
Due to an issue with the interrupt-based transfer API from QMSI driver,
the 'transfer' callback from the shim driver (i2c_qmsi_transfer) is
implemented with polling APIs. This is not ideal because we are not able
to sleep the current thread (so another task can be scheduled in) while
the i2c operation is carried out.

The interrupt issue with the QMSI driver has been solved then this patch
fixes the shim driver so it uses the interrupt-based API and adds extra
code to handle the thread synchronization.

Finally, this patch also moves all 'struct device' related definitions
from the bottom to the top of the i2c_qmsi.c file so the DEVICE_GET
macro can be used in transfer_complete() and removes the init.h include
since it is not needed anymore.

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.
