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.

Dragan Cvetic eb147c650c spi_qmsi: Add suspend/resume
This patch implements suspend/resume routines which
preserve SPI master 0 and 1 context in SYS_PM_DEEP_SLEEP.
The following parameters are suspended/resumed:
- All non-sticky RW registers for the SPI device which
  are not related to a transfer.
- The SPI MASK registers (interrupt routing register).

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.

Johan Hedberg 0efd558cbc SPI: Change read/write buffer pointers to void *
There's no reason to require callers to cast their data to uint8_t *
when the data might e.g. originate in a packed struct or some other
data type. Instead, be nice to callers and let them use any pointer
they want. Additionally, declare the TX buffer as a const pointer so
unnecessary typecasts aren't needed for that either (if the data
originates in a const location).

Andre Guedes 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.

Vinicius Costa Gomes b5ff3fe0dd spi: qmsi: Fix enabling the CS line too late
There are situations when the transfer starts before we have the time to
enable the CS line, so to be sure, we active it before even attempting
to start the transfer.

This fixes an CC2520 driver initialization issue using the QMSI SPI driver.

Vinicius Costa Gomes 8166cf8d8f spi: qmsi: Add support for selecting the driver's init priority
Because of the necessity of using a GPIO pin as Chip Select, we need to
set the initialization priority of the SPI driver so it occurs after the
GPIO driver.

Vinicius Costa Gomes 39d87755c1 spi: qmsi: Add support for using a GPIO pin as CS
There are cases that it is needed to use a GPIO pin as chip
select (frames would be too long, for example), so using a GPIO pin as
chip select to keep the line active while the transfer is ongoing is the
usual solution.

This implements that solution for the QMSI shim driver.
