drivers: adc: add ADC emulator 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/ Signed-off-by: Tomasz Michalec <tm@semihalf.com>

drivers: adc: Update drivers to use devicetree Kconfig symbol Update adc drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>
