c67b44c96a drivers: counter: Added get_freq to API
Optional counter API function which allows for a driver to determine
counter frequency at runtime; if set, this supersedes whatever is set
statically in the counter_config_info struct.

This commit adds a generic i2c regulator driver, and enables the NXP

additional API in include/drivers/regulator/consumer.h, which allows
drivers to implement support for adjusting voltage levels and current
limits, if their device supports it.

deb1b455b9 drivers: can: improve API documentation
Improve the CAN driver API documentation:
- Reorder API declarations and organize them into logical groups.
- Add doxygen strings where missing.
- Improve and unify wording of existing doxygen strings.
- Unify naming of callback function pointers as "callback".
- Unify naming of user-specified callback function arguments as
  "user_data".
- Instances and pointers to struct zcan_frame are named "frame",
  not "msg", to avoid confusion with the CAN message queue support.
- Check for __DOXYGEN__ to include documentation for optional APIs in
  the documentation.
- Use "@cond INTERNAL_HIDDEN" to hide internal API details such as padding.

7b1349cfe6 stats: i2c: I2C stats
Adds the ability for I2C drivers to report synchronous transfer stats
using a I2C specific macro to define the device instance.

The macro creates a container for device_state which allows for per
instance device class common data structure to be used in the device
class api (ex: i2c.h). This is used to maintain per driver instance
stats for all i2c drivers. This is a reusable idea across other device
classes as desired.

Using Kconfig device class stats may be turned on/off individually
this way as well, in this case I2C_STATS.

1c1a2ccdbd dts/bindings: Add a dedicated frame format property on SPI device
Most of the time SPI devices use TI's frame format. But some may use
Motorola's. This is already taken care of in the SPI API and now it will
be possible to select the right format from DTS. Like:

    ...
    frame-format = <SPI_FRAME_FORMAT_MOTOROLA>;
    ...

This is only meant to be used for devices supporting both formats (so
the format is not hard-coded in the driver) and selected by hardware
configuration or else.  Which, in such case, it will need to use
DT_INST_PROP(<instance number>, frame-format) macro call to retrieve
the property value. Others can fully ignore it.

f8f2936dba pcie: add initial controller support
This adds :
- Generic PCIe Controller layer implementing the current PCIe API
- Generic PCIe Controller in ECAM mode driver

The Generic PCIe Controller layer provides:
- Configuration space read/write
- single bus endpoint enumerations
- Endpoint I/O, MEM & MEM64 BARs allocation
- Endpoint I/O, MEM & MEM64 BARs get & translation for drivers

The Generic PCIe Controller in ECAM mode driver provides:
- Raw DT RANGES properties into usable PCIe regions
- Configuration space read/write into ECAM config space
- PCIe regions allocation & translation

The limitations are:
- No support for PCIe prefetchable regions
- No support for PCIe bus configuration (only bus0 is supported)
- No support for multiple controllers (no domain-id in BDF)

Support has been designed to initially support Root Complexes with
Root Complex Integrated Endpoint, which was designed for Embedded
Systems with internal-only PCIe Endpoints on bus 0.

5a9bc389f0 driver: gpio: nct38xx: Add NCT38XX gpio driver support
NCT38XX series, which are i2c-based chips, support a different number
of GPIO functionality. For NCT3807, it has 2 GPIO ports on the same i2c
device address. For NCT3808, it has 2 GPIO ports on different i2c
device addresses. This commit adds NCT38XX GPIO driver support &
provides the interrupt handler for the share alert pin.

The following is NCT3807 devicetree node example:
```
&i2c0_0 {
	nct3807_0: nct3807@70 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "nuvoton,nct38xx-gpio";
		reg = <0x70>;
		label = "NCT3807_0";

		gpio@0 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x0>;
			label = "NCT3807_0_GPIO0";
			gpio-controller;
			#gpio-cells = <2>;
			ngpios = <8>;
			pin_mask = <0xff>;
			pinmux_mask = <0xf7>;
		};

		gpio@1 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x1>;
			label = "NCT3807_0_GPIO1";
			gpio-controller;
			#gpio-cells = <2>;

4bd5935302 dts/bindings: Add a dedicated property for duplex mode on SPI device
Users will have to include dt-bindings/spi/spi.h in order to use the
relevant flags fol this property. For instance:

    ...
    duplex = <SPI_HALF_DUPLEX>;
    ....

By default all SPI device are configured to be full duplex so the
property is optional. This property makes sense only for devices that
can be configured on either modes. Which, in such case, it will need to
use DT_INST_PROP(<instance number>, duplex) macro call to retrieve the
property value. Others can fully ignore it.

f8cc93de8c spi: Add a configuration option for half/full duplex mode
This is meant to expose half/full duplex configuration option on regular
configuration. So far, dual/quad/octal are not exactly supported, as it
would require extensions to the SPI buffer for a full support.

So moving these modes to an extended operation attribute
(32 vs 16 bits), disabled by default.

And exposing half/full duplex configuration bit. Full duplex being the
default option.

60827c2dd6 include/spi: Clarify spi_release() function behavior
It will unlock and unhold the CS line. Note that the lock and the CS
being hold on are 2 separate config bits, so if only one is selected
spi_release() will only apply on this configuration.

Note: this has been already the case in the controller drivers, where
there implementation of spi_release() calls
spi_context_unlock_unconditionally(). And that function always forces
the CS line to an inactive state.

1976f33e87 drivers: mbox: Introduce MBOX driver class
One limitation of the current IPM API is that it is assuming that the
hardware is only exporting one single channel through which the data can
be sent or signalling can happen.

If the hardware supports multiple channels, the IPM device must be
instantiated (possibly in the DT) several times, one for each channel to
be able to send data through multiple channels using the same hw
peripheral. Also in the current IPM API only one callback can be
registered, that means that only one driver is controlling all the
signalling happening on all the channels.

This patch is introducing a new MBOX API that is supporting
multi-channel signalling and data exachange leveraging and extending the
previous (and outdated) IPM API.
