84d90e456a driver: intc: add MIWU driver support in NPCX series.
The device Multi-Input Wake-Up Unit (MIWU) supports the embedded
controller (EC) to exit 'Sleep' or 'Deep Sleep' power state which allows
chip has better power consumption. Also, it provides signal conditioning
such as 'Level' and 'Edge' trigger type and grouping of external
interrupt sources of NVIC. The NPCX series has three identical MIWU
modules: MIWU0, MIWU1, MIWU2. Together, they support a total of over 140
internal and/or external wake-up sources.

In this CL, we use device tree files to present the relationship bewteen
MIWU and the other devices in different npcx series. For npcx7 series,
it include:
1. npcx7-miwus-int-map.dtsi: it presents relationship between MIWU group
   and NVIC interrupt in npcx7. Please notice it isn't 1-to-1 mapping.
2. npcx7-miwus-wui-map.dtsi: it presents relationship between input of
   MIWU and its source device such as gpio, timer, eSPI VWs and so on.

This CL also includes:
1. Add MIWU device tree declarations.
2. MIWU api function declarations and implementation to configure signal
   conditions and callback function mechanism. They can be be classified
   into two types. One is for GPIO which connects original gpio callback
   implemetation and the other is for generic devices such as timer,
   eSPI, and so on.

63c3e153d6 drivers: use node IDs for DEVICE_MMIO.*_INIT
There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.

Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

ccb4b1ec47 drivers: interrupt_controller: GIC barrier before EOI
It is desired to have the peripheral writes completed to clear the
interrupt condition and de-assert the interrupt request to GIC before
EOI write. Failing which spurious interrupt will occur.

A barrier is needed to ensure peripheral register write transfers are
complete before EOI is done.

GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point
of view. However these writes may pass over different interconnects,
bridges, buffers leaving some rare chances for the actual write to
complete out of order.

GICv3 ICC EOI system register writes have no ordering against nGnR(n)E
memory writes as they are over different interfaces.

Hence a dsb can ensure from core no writes are issued before the
previous writes are *complete*.

e8b6b86704 interrupt_controller: device driver can configure IO APIC delivery mode
Currently all IO APIC interrupts are configured at fixed delivery mode,
which is good for HEPT timer interrupt but it imposes burdens to
device drivers to properly handle the repeated interrupt sent to all
processors.

This patch makes it more flexible so that device drivers can specify
the delivery mode it desires in the IRQ connect APIs.

- Don't hard code IOAPIC_FIXED in z_ioapic_irq_set(), meaning the
  IRQ delivery mode is passed in from the 'flags' argument and
  individual device driver needs to choose delivery mode for its own
  IO APIC interrupt.

- To support different delivery mode in different IO APIC interrupts,
  need to save and restore RTE[10:8] during IOAPIC suspend and resume.

If device driver doesn't pass either IOAPIC_FIXED or IOAPIC_LOWEST
in IRQ_CONNECT()/irq_connect_dynamic() alike APIs, the delivery mode
bit fields in the target RTE register are '0' which implies fixed mode.
If the device driver wants the interrupt to be delivered to one CPU
only, it needs to explicitly specify IOAPIC_LOWEST in one of the IRQ
connect APIs.

d27f6cb5eb interrupt_controller: program local APIC LDR register for xAPIC
If IO APIC is in logical destination mode, local APICs compare their
logical APIC ID defined in LDR (Logical Destination Register) with
the destination code sent with the interrupt to determine whether or not
to accept the incoming interrupt.

This patch programs LDR in xAPIC mode to support IO APIC logical mode.

The local APIC ID from local APIC ID register can't be used as the
'logical APIC ID' because LAPIC ID may not be consecutive numbers hence
it makes it impossible for LDR to encode 8 IDs within 8 bits.

This patch chooses 0 for BSP, and for APs, cpu_number which is the index
to x86_cpuboot[], which ultimately assigned in z_smp_init[].

7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

50519ce7ba interrupt_controller: gic: Refactor GIC driver interface
The current Generic Interrupt Controller (GIC) driver makes use of the
multi-level interrupt mechanism and `irq_nextlevel` public interface.

This is a less-than-ideal implementation for the following reasons:

1. The GIC is often used as the main interrupt controller for the
  Cortex-A and Cortex-R family SoCs and, in this case, it is not a 2nd
  level interrupt controller; in fact, it is the root interrupt
  controller and therefore should be treated as such.

2. The only reason for using `irq_nextlevel` here is to interface the
  architecture implementation to the interrupt controller functions.
  Since there is no nesting or multiple instances of an interrupt
  controller involved, there is really no point in adding such an
  abstraction.

3. 2nd level topology adds many unnecessary abstractions and results
  in strange coding artefacts as well as performance penalty due to
  additional branching.

This commit refactors the GIC driver interface as follows:

1. Remove the current GIC driver interface based on the multi-level
  interrupt mechanism and the `irq_nextlevel` public interface.

2. Define the GIC driver interface in
  `include/drivers/interrupt_controller/gic.h` and allow the arch
  implementation to directly invoke this interface.

7baf3f74a9 interrupt_controller: gic: Support PPIs
The GIC-400 driver currently only supports SPIs because the (32) offset
for the INTIDs is hard-coded in the driver. At the driver level there is
no really difference between PPIs and SPIs so we can easily extend the
driver to support PPIs as well.

This is useful if we want to add support for the ARM Generic Timers that
use INTIDs in the PPI range.

SPI interrupts are in the range [0-987]. PPI interrupts are in the range
[0-15].

This commit adds interrupt 'type' cell to the GIC device tree binding
and changes the 'irq' cell to use interrupt type-specific index, rather
than a linear IRQ number.

The 'type'+'irq (index)' combo is automatically fixed up into a linear
IRQ number by the scripts/dts/gen_defines.py script.

975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Some code in stm32 exti driver was considering exti lines number
for which no IRQ_CONNECT was available. To be clear, this code
was not functional and since no one complained it was not used.
Besides, code to take into account these "high" irq lines was
complex hard to read and review.
Simplify state of things by removing completely this part of code.
It could be put back again piece by piece when required.

4462069d74 drivers: gpio: sam0: Add interrupt support
This adds interrupt support to the SAM0 GPIO driver.  This is heavily
inspired by @nzmichaelh work in #5715.  The primary difference
from that implementation is that here the External Interrupt
Controller (EIC) is separated out into an interrupt controller driver
that is less tightly coupled to the GPIO API.  Instead it implements
more of a conversion from the EIC's own odd multiplexing to a more
traditional port and pin mask IRQ-like callback.  Unfortunately,
through the EIC on the SAMD2x are relatively well behaved
in terms of pin to EIC line mappings, other chips that share the
peripheral interface are not.  So the EIC driver implements a
per-line lookup to the pin and port pair using definitions extracted
from the ASF headers.

The EIC driver still makes some assumptions about how it will be used:
mostly it assumes exactly one callback per port.  This should be fine
as the only intended user is the GPIO driver itself.

This has been tested with some simple programs and with
tests/drivers/gpio/gpio_basic_api on a SAMD21 breakout and an
adafruit_trinket_m0 board.

e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

linker and usb files. These are

to support SoCs with more than four level 2 interrupt "aggregators".

Extend existing support to allow at most 8 level 2 or level 3

Try to clarify some aspects of the Kconfig help while we're at it, and
change the type of options which count things or are table offsets
from "hex" to "int", so that the generated .config is easier to read.

Finally, make some improvements to gen_isr_tables.py while we are

duplicated work, don't check for symbols we know must exist, and
