menuconfig PLATFORM_EC_ADC
	bool "ADC shim"
	default n if ARCH_POSIX
	default y
	help
	  Enable compilation of the EC ADC module. Once enabled, it is
	  possible to call platform/ec adc_read_channel() function.

if PLATFORM_EC_ADC

config PLATFORM_EC_ADC_CMD
	bool "ADC host/console command"
	default y
	help
	  Enables support for printing ADC channels state with the "adc"
	  console command and reading a state of ADC channel with the
	  EC_CMD_ADC_READ host command. Replaces generic Zephyr "adc"
	  command.

config PLATFORM_EC_ADC_RESOLUTION
	int "ADC resolution"
	default 10
	help
	  The resolution, in bits, to use for the ADC conversion. Determines
	  the sample values range: 0 .. 2^resolution -1. The supported
	  resolution values depend on specific hardware.

config PLATFORM_EC_ADC_OVERSAMPLING
	int "ADC oversampling"
	default 0
	help
	  ADC oversampling to use for the ADC conversion. Each sample is
	  averaged from 2^oversampling conversion results. Oversampling can
	  help in providing more stable readings. The supported oversampling
	  values depend on specific hardware.
