This commit adds support for the Parade Tech TMA525B capacitive touch
controller. The driver supports both interrupt-driven and polling modes,
and can handle up to 4 simultaneous touch points.
Key features:
- I2C communication interface
- Multi-touch support (up to 4 touch points)
- Interrupt mode with GPIO callback support
- Polling mode with timer
- Power management support with PM notifier
- Reset and power control via GPIO
- Touch event tracking (down, contact, up)

Add a new sleep-mode-enable property for the Cirque Pinnacle input driver,
to enable the sleep-mode for those peripherals, which will go into a lower
power state after 5 seconds with no fingers detected.

Add Kconfig option to skip or execute the verification of the ic

The sensor requires at least 94ms of delay before starting

The CHSC5X chip requires reads to be aligned to multiples of 4 bytes.
If the read length is not a multiple of 4, the device pulls SDA/SCL low
for about 140 ms. The IC_TYPE address is corrected to 0x80.

If the process does an exec() (or fork, or..) all descriptors are kept
open by default, unless O_CLOEXEC is set when opening them.
This is usefull for stdin/out/err so that new process is connected to
them, but it is very rare for it to be usefull for any other descriptor.
In general this leads to descriptors being kept open unnecessarily,
which either will block other process from getting them (for example
if the child survives the parent but it does something else).
Or for a "leak" which unnecessarily uses descriptors and memory in the
child process.
Let's ensure we do not leak it for this component as we do not need it.

When the kso[17:16] lines are enabled and `CONFIG_ASSERT` is
configured, the following error occurs: "Input cannot be
enabled for 'Open Drain', 'Open Source' modes without Output."
To address this, this commit configures kso16 and kso17 as
gpio output before applying the pinctrl settings.

The kso_ignore_mask DTS property was not being fully applied in the
ITE IT8xxx2 keyboard driver:
1. The driver performed direct writes to the KBS_KSOH2 register,
which controls KSO[17:16]. This did not account for the
kso_ignore_mask and could overwrite bits in the register that
are used for other GPIO functions.
2. The driver would attempt to initialize the GPIOs for KSO16 and
KSO17 based solely on the col-size property. It ignored the
kso_ignore_mask, which could lead to reconfiguring a pin that
is intended for another purpose.

A kernel panic was observed on a platform when k_sem_give() was called
in npcx_kbd_ksi_isr(). From the panic information, it appears that
the semaphore was used before it was initialized. This commit prevents
the potential issue by enabling the interrupt only after
the input_kbd_matrix_common_init() function is called
(where the semaphore is initialized).

When the device was suspended and the pin level changed during
that time, the pin level of course isn't updated in the pins cb_data.
Once the device is resumed, this leads to potentially having
a wrong value in the pin state data leading to swallowing the first
event due to comparing the stored level vs. the new level before
reporting.
Also added some `const`s and deleted an unused struct element.

Certain power modes lose state of the GPIO, hence we need to

The previous implementation already reported a key-press event after
reading an ADC value close to the threshold for the first time.
This may lead to false events if the ADC takes a reading just during
the transition from one button state to another (especially if a
somewhat large capacitor is used to avoid noise).
A key-press state must be same for at least two samples in order to
avoid such issues, which is what this commit implements.

The VS1838B is one of the most found infrared receiver
found in electronic kits and is easy to setup with only
a single GPIO used for signal transmission (apart from
VCC and GND).
This new driver let applications use the VS1838B as an
input with events relayed as 0x0000<address><command>.
Only the NEC protocol is supported in this version but
more can be added later.

Under certain conditions report_lock could already be used by the irq
before it was initialized, now we ensure we enable irq after report_lock
is initialized.
Furthermore in some conditions data->xfer_bytes could be equal
SBUS_FRAME_LEN resulting in a infinite loop doing zero reads when
fifo is still holding new bytes
