Gerard Marull-Paretas a5fd0d184a init: remove the need for a dummy device pointer in SYS_INIT functions
The init infrastructure, found in `init.h`, is currently used by:

- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices

They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:

```c
struct init_entry {
	int (*init)(const struct device *dev);
	/* only set by DEVICE_*, otherwise NULL */
	const struct device *dev;
}
```

As a result, we end up with such weird/ugly pattern:

```c
static int my_init(const struct device *dev)
{
	/* always NULL! add ARG_UNUSED to avoid compiler warning */
	ARG_UNUSED(dev);
	...
}
```

This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:

```c
static int my_init(void)
{
	...
}
```

This is achieved using a union:

```c
union init_function {
	/* for SYS_INIT, used when init_entry.dev == NULL */
	int (*sys)(void);
	/* for DEVICE*, used when init_entry.dev != NULL */
	int (*dev)(const struct device *dev);
};

struct init_entry {
	/* stores init function (either for SYS_INIT or DEVICE*)
	union init_function init_fn;
	/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
	 * to know which union entry to call.
	 */
	const struct device *dev;
}
```

This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.

**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Mulin Chao b1214ead19 driver: i2c: npcx: simplify smb bank registers with union
For NPCX SMB/I2C SMB modules in FIFO mode, the registers include:

* Common registers, offset 0x00-0x0f, accessible regardless of the value
  of BNK_SEL
* Bank 0 registers, offset 0x10-0x1e, accessible if BNK_SEL is set to 0
* Bank 1 registers, offset 0x10-0x1e, accessible if BNK_SEL
is set to 1

In the current driver, it uses two structures, `smb_reg` and
`smb_fifo_reg`, to access `Common + Bank 0` and `Common + Bank 1`
registers. But It might be easy to misunderstand that they are two
different modules.

This CL tries to simplify this by the following steps:

1. Use `union` to combine `Bank 0/1` registers in the same structure.
2. Remove `smb_fifo_reg`. We needn't use two structures to present
   SMB registers.

Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Mulin Chao 851e357aa4 pinctrl: npcx: add pinctrl support for psl pads
This CL introduces how to configure PSL (Power Switch Logic) pads
properties such as input detection mode/polarity, pin-muxing and so
on via pinctrl mechanism. It includes:

1. Add two pinctrl properties and their enums for PSL input
   detection configuration.
    psl-in-mode:
      - "level"
      - "mode"
    psl-in-pole:
      - "low-falling"
      - "high-rising"

2. Add macro functions to get PSL input detection and pin-muxing
   configurations from 'pinmux', 'psl-offset' abd 'psl-polarity'
   properties.

Here is an example to configure PSL_IN2 as the PSL detection input and
its mode and polarity.

/* A falling edge detection type for PSL_IN2 */
&psl_in2_gp00 {
	psl-in-mode = "edge";
	psl-in-pol = "low-falling";
};

A device will be introduced later which uses this pinctrl node to
configure PSL input detection settings and how to turn off VCC1 power
rail by PSL_OUT.

Mulin Chao 0f18c4c4ab pinctrl: npcx: config pwm open-drain without enabling STORE_REG
Config pwm open-drain mode without enabling STORE_REG. This CL
collects all active PWM's base address and related index in an
array. Then, pinctrl driver configs its open-drain mode by
finding the corresponding 'channel' index.

Mulin Chao d53d574bf0 drivers: pinctrl: npcx: add initial pin-controller driver
This CL is the initial version for npcx pinctrl driver and introduces
pinctrl nodes for both IO-pads and peripheral devices for each npcx
series. Users can set pin configuration via these nodes in the board
layout DT file. It also wraps all configurations related to pin-muxing
in pinctrl_soc.h. Regarding the other pin properties, we will implement
them later.

Jun Lin 51978d9d61 driver: eSPI: npcx: workaround the errata rev1_2, No.3.10
Enabling an eSPI channel (r.g. Peripheral Channel, Virtual Wire Channel,
etc.) during an eSPI transaction might (with low probability) cause the
eSPI_SIF module to transition to a wrong state and therefore response
with FATAL_ERROR on an incoming transaction.
This CL workarounds this issue by clearing the bit 4 of NPCX eSPI
specific register#2.

ADC threshold control register offset is provided by devicetree, this
change will add this property into `adc_npcx_config` structure and
update macro to access register accordingly. Driver behavior is not
meant to be impacted.
