12ac3fde4a ITE: drviers/adc: Adjust the wait time for acquiring a semaphore
After the ADC interrupt is enabled, the interrupt will be triggered
and the ADC channel valid data will be read, so there is no time
limit here.
Refer to the timeout is also set to K_FOREVER in the function of
adc_context_wait_for_completion().

9a18fdea3f drivers: Check and fix device const qualifier on ISR
Re-running the script that checks for the const qualifier missing on
struct device ISR's parameter.

The script also changes the parameter 'arg' to 'dev' when relevant.

4381841bd8 ITE: drivers/adc: fix the sampling flow of ADC
The ADC sampling of it8xxx2 needs to read each channel in sequence,
so it needs to wait for an interrupt to read data in the loop
through k_sem_take().

In test_adc.c, k_timer_start() is used in the interval test, so we
need to use polling wait instead of k_sem_take() to wait, otherwise
it will cause kernel panic.

k_is_in_isr() can determine whether to use polling or k_sem_take()
at present.

b0cdef3c25 drivers: adc: Refactor drivers to use shared init priority
Refactors all of the ADC drivers to use a shared driver class
initialization priority configuration, CONFIG_ADC_INIT_PRIORITY, to
allow configuring ADC drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.

The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are lmp90xxx, mcp320x, and mcux_adc16 drivers which have
dependencies on GPIO, SPI, and/or DMA drivers and must therefore
initialize later than the default device priority.

8ea58d4389 ite: drivers/adc: create pinmux phandle to the ADC driver node
Create the pinmux phandle to the ADC driver node in the
devicetree. When the pinmux_pin_set function in
adc_it8xxx2_channel_setup can refer to the setting of
this phandle. It is more flexible to use.
