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.

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.

8a4013b2e1 drivers: adc: Set correct interrupt type and remove spurious interrupts
In npcx adc driver, we select 'Scan' (Multiple Channels Operation Mode)
mode by default. It means that selected channels in ADCCS will be
converted automatically. Then, read the measured data from CHNDAT
registers if EOCCEV (Event is set after all selected channels are
converted.) flag in ADCSTS is set.

But we enable the wrong interrupt type, INTECEN, during adc
initialization. Ec will send the interrupt after each channel in ADCCS
is converted. It has no harm to the current driver since the driver
reads all selected channels and turns off ADC converter only after
EOCCEV is set in ISR. But it does generate spurious interrupts.

This CL enables the correct interrupt type, INTECCEN, during adc
initialization. Ec only sends the interrupt after all of channels in
ADCCS are converted.

db74010cc7 drivers: uart: npcx: use PM constraint for the receiving
In this commit, the driver sets the PM constraint to prevent the system
from entering the suspend state for a CONFIG_UART_CONSOLE_INPUT_EXPIRED
period when data come in. The constraint releases after the
CONFIG_UART_CONSOLE_INPUT_EXPIRED time expires, .

With this change, the PM policy doesn't have to check the timestamp
by calling npcx_power_console_is_in_use() explictly. So the related
npcx_power_console_is_in_use*() functions can be removed.
