The ADC module has four conversion groups, each one is set up as a zephyr
device. The start-up calibration is initiated globally for all groups
and it is run in each device init function. The ADC module supports post
calibration per group. Post calibration is run automatically after each
group acquires the samples.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

New ADC driver for the TI CC13xx/CC26xx family.
ADC channel configurations are translated from Zephyr constants to
simplelink driverlib ones (e.g., sample times use a lookup table).
Async mode was also implemented & tested.

Define RaspberryPi Pico ADC.
The ADC has internally connected temperature sensor,
Add property to enable this.
The ADC has a single VREF. VCC usually connects to it,
but it may not be in a case.
Add property to make configurable it.

Use the clock control API to turn on ADC clocks. Note that clock

ADC emulator is designed to be used in tests on native_posix board. It
supports 1-16 bit resolution range and all GAINs from enum adc_gain.
Reference voltages and number of emulated channels are set through dts.
Using special API from drivers/adc/adc_emul.h it is possible to set
constant voltage value returned by given ADC channel or set custom
function which allows to simulate complex output.
Also reference voltages can be changed in runtime using the API.
The CL also includes:
- Add adc definitions of ADC emulator in
tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.
- Add test for ADC emulator API in tests/drivers/adc/adc_emul/
