Semaphore groups are not supported by the unified kernel (other than
via the legacy APIs).
A select() or poll() type mechanism may be introduced in the future
to provide a more general capability for a thread to wait on multiple
kernel objects simultaneously.

Implement qmsi shim driver based on the new API interfaces.
Recently, a RFC was sent and discussed on the re-design of
PWM interfaces. A API change was already posted.
The API new design will deprecate all existing APIs and three
new APIs will be added. The new APIs are pwm_pin_set_cycles,
pwm_pin_set_usec and pwm_get_cycles_per_sec. Pwm_pin_set_cycles
and pwm_pin_set_usec will rely on two driver functions to set
the period and pulse width. This change is to implement the
driver functions pwm_qmsi_pin_set and pwm_qmsi_get_cycles_per_

APIs like pwm_pin_set_values, pwm_pin_set_period, pwm_pin
_set_duty_cycle will be deprecated and replaced by the new

A new API pwm_get_cycles_per_sec will be added to get the
clock rate for pwm pins.
The API pwm_pin_set_phase will be deprecated(it always sets
the phase to zero).
The API pwm_pin_configure will be deprecated since it is not
doing anything for most of the platforms or it can be moved
to device init function for the other platforms.
All the pwm_all_xxx APIs will be deprecated. If necessary,
user or an app can set the pins individually.

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.

Before, the kernel would run the main() function twice; first
as an entry in k_task_list, and then again from _main(). The
_main() invocation would be using a potentially insufficient stack
size.
Now if an MDEF file declares a main() thread, invoke it from
_main(), but honor the desired priority and stack size.

Event is such an overloaded and generic term (event logger, *kernel*
event logger, "protocol" events in other subsystems, etc.), that it is
confusing for the name an object. Events are kinda like signals, but not
exactly, so we chose not to name them 'signals' to prevent further
confusion. "Alerts" felt like a good fit, since they are used to "alert"
an application that something of significance should be addressed and
because an "alert handler" can be proactively registered with an alert.

Since net_buf_get() for the avail_acl_tx FIFO is called in
interrupt context (ISR) it cannot wait, and it will fail
immediately returning NULL if it fails to acquire a buffer.
During LE Secure Connections pairing, when there is a fair
amount of packets coming from the host, the FIFO was running
out of buffers causing the packet to be dropped instead of
forwarding it to the controller.
The number allocated now matches the amount of TX buffers
in the controller, so that normal HCI flow control (from
the Host to the Controller) will kick-in preventing any
buffers from being dropped.
