This driver supports the TI INA230 and INA231 Bidirectional Current
and Power Monitors. The devices work on the I2C interface and are
created from DT nodes with a compatible property matching "ti,ina23x".
The following datasheets were referenced while developing the driver:

Testing was performed on the stm32g071b_disco board with the following:
Load: ~170 ohms
Voltage: 5V
Measured Values:
Voltage: 5.1 V

The KBC/ACPI event data is 4-byte in width and composed of
event/data/type fields. However, the field position is defined by each
chip vendor via macro and not unified in the current implementation.
The commit uses the structure bit field to define and unify the field
position. It helps the application access it with a common approach.

Add driver implementation and header files for a MEC172x
aggregated interrupt driver. Enable the parent(ECIA) node
to have the driver initialize interrupt hardware for use.
Enable child nodes for those GIRQs used for aggregation.
Refer to chip documention for the list of GIRQs restricted
to aggregation and those which support direct mode.
Add chip level device tree node for MEC172x EC interrupt
aggregator parent and GIRQ children. Each child node contains
a list of sources representing the source bit position in the
GIRQ registers.
Add DT bindings for ECIA and GIRQ nodes.
Add build file(s) and configuration items for the MEC172x ECIA
aggregated interrupt driver. Add and enable the MEC172x interrupt
driver on the MEC172x evaluation board(EVB). Enable parent node to
initialize ECIA hardware. Child nodes are left disabled until a
future driver needs them.

Implement a clock control driver for Microchip MEC172x handling
configuring the 32 KHz input sources for the PLL and peripheral-32k
clock domains. MEC172x differs from MEC152x. MEC152x had one 32K source
for both PLL and peripherals. MEC172x allows the two domains to use
independent 32 KHz sources. Device tree updated to provide addresses
of hardware used by the driver.

A syscon device is a device managing a memory region containing a set of
registers that are not cohesive enough to represent as any specific type
of device. We need a driver for that because several other drivers could
use the same region at the same time and we need to io-map the region at
boot for MMU enabled platforms.

Move all PM_DEVICE_STATE_* definitions to an enum. The
PM_DEVICE_STATE_SET and PM_DEVICE_STATE_GET definitions have been kept

name has not been changed since they will be removed soon.
All drivers and tests have been adjusted accordingly.

Introduces the `struct spi_dt_spec` type, which contains the complete
SPI bus information derived from devicetree. It serves the same purpose
as `struct gpio_dt_spec` in that it can be constructed automatically in
`DEVICE_DT_INST_DEFINE` macros and provided as a single handle to SPI
API calls. Includes a single function, `spi_is_ready` that validates all
SPI bus dependencies are ready.

The cache API currently shipped in Zephyr is assuming that the cache
controller is always on-core thus managed at the arch level. This is not
always the case because many SoCs rely on external cache controllers as
a peripheral external to the core (for example PL310 cache controller
and the L2Cxxx family). In some cases you also want a single driver to
control a whole set of cache controllers.
Rework the cache code introducing support for external cache
controllers.

To keep compatibility between the old GPIO API implementation and a new
one introduced in the Zephyr 2.2.0 release the gpio_pin_configure()
function was accepting interrupt flags. In the new API implementation
interrupt flags are only accepted by gpio_pin_interrupt_configure()
function.
This temporary support for INT flags in gpio_pin_configure should have
been removed in the Zephyr 2.4.0 release.

ADC emulator is designed to be used in tests on native_posix board. It
supports 1-16 bit resolution range and all GAINs from enum adc_gain.
Reference voltages and number of emulated channels are set through dts.
Using special API from drivers/adc/adc_emul.h it is possible to set
constant voltage value returned by given ADC channel or set custom
function which allows to simulate complex output.
Also reference voltages can be changed in runtime using the API.
The CL also includes:
- Add adc definitions of ADC emulator in
tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.
- Add test for ADC emulator API in tests/drivers/adc/adc_emul/

In prts of the code, we use rcc node "clocks" property to testify the
use of device tree for clocks configuration.
This doesn't work in case of stm32h7 m4 targets as for those,
"upstream rcc" clock configuration, such as sysclk source selection,
is done on m7 core and hence rcc node doesn't have a "clocks"
property.
To work around this, use alternate "d1cpre" property in case of
stm32h7 targets.
