ab49673bc8 drivers: timer: nrf_rtc_timer: Change type of channel argument
There was an inconsistency in the API as z_nrf_rtc_timer_chan_alloc
returned int but other function were using uint32_t for channel
argument. Updated api to use int32_t everywhere.

Update nrf_802154 driver which was using this api to use int32_t.

9c1efe6b4b clock: remove z_ from semi-public APIs
The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers

used outside of the clock/kernel subsystems.

915f4ac3c7 drivers/interrupt_controller: Get the IOAPIC RTEs dynamically
The fixed number of 24 RTEs is a legacy thing, and long gone by now.
IOAPICs expose the maximum number of RTEs they have via the version

This avoids to manually tweak a Kconfig option (which is now removed)

0f9406277d aarch64: pm_cpu_ops: Introduce pm_cpu_ops subsystem
AArch64 has support for PSCI. This is especially useful for SMP because
PSCI is used to power on the secordary cores.

When the PSCI driver was introduced in Zephyr it was designed to rely on
a very PSCI-centric subsystem / interface.

There are two kinds of problems with this choice:

1. PSCI is only defined for the non-secure world and it is designed to
   boot CPU cores into non-secure state (that means that PSCI is only
   supposed to work if Zephyr is running in non-secure state)

2. There can be other ways or standards used to start / stop a core
   different from PSCI

This patch is trying to fix the original wrong assumption by making the
interface / subsystem a generic one, called 'pm_cpu_ops', and using PSCI
only as an actual driver that is a user of this new interface /
subsystem.

For now the new subsystem is only exposing two methods: cpu_on and
cpu_off, others will probably follow according to the needs.

d6cfa10b8f drivers: spi: add helpers for initializing from DT
Add helper macros for initializing a struct spi_sconfig for a SPI
device which is defined in the devicetree. They are available from C
only due to C++ compatibility issues.

For some fields, like 'frequency', we just get the value from the
standard devicetree property. For others, like the spi_cs_control
structure's 'gpio_dev', we rely on the new DEVICE_DT_GET() macro.

This patch does not change anything for controlling SPI devices that
aren't set up in devicetree. It is entirely a convenience for driver
and application code that relies on DT.

8f8cdc18c4 gpio: clean up flags related to logical initialization
The wrapper function detects when a logic-level initial value requires
inverting the physical level initial value, and updates the flags to
effect the necessary change.  However where logical and physical
levels are not inverted the flag requesting logic-level initialization
was left in place and passed to a driver that got confused by it.

Clear the flag after its purpose has been addressed.

57f7e31017 drivers: PSCI: Add driver and subsystem
Firmware implementing the PSCI functions described in ARM document
number ARM DEN 0022A ("Power State Coordination Interface System
Software on ARM processors") can be used by Zephyr to initiate various
CPU-centric power operations.

It is needed for virtualization, it is used to coordinate OSes and
hypervisors and it provides the functions used for SMP bring-up such as
CPU_ON and CPU_OFF.

A new PSCI driver is introduced to setup a proper subsystem used to
communicate with the PSCI firmware, implementing the basic operations:
get_version, cpu_on, cpu_off and affinity_info.

The current implementation only supports PSCI 0.2 and PSCI 1.0

The PSCI conduit (SMC or HVC) is setup reading the corresponding
property in the DTS node.
