* zephyr: adc: add a dedicated NAMED_ADC_CHANNELS optionFabio Baltieri2022-12-191-3/+10
| | | | | | | | | | | | | | | | | | | | | Add a dedicated NAMED_ADC_CHANNELS option to decouple the platforms setting from the Zephyr ADC one. This allows running tests for code that uses only the Zephyr APIs without having to define named channels as well. Also allows dropping some #if guards that made no sense since they were guarding a data structure used outside of the guard.

* zephyr: Delete CONFIG_PLATFORM_EC_ADCKeith Short2022-08-011-11/+3
| | | | | | | | | | | | | | | | | | | CONFIG_PLATFORM_EC_ADC is redundant with the Zephyr Kconfig option, CONFIG_ADC. Use the Zephyr option directly. Note - projects based on the "minimal" config do not compare. The minimal config disabled CONFIG_ADC, but the CONFIG_PLATFORM_EC_ADC_CMD was still enabled. With this CL, CONFIG_PLATFORM_EC_ADC_CMD now depends on CONFIG_ADC.

* zephyr: add shim ADCDawid Niedzwiecki2021-02-091-0/+41
Add ADC shim to connect the platform/ec ADC API to the Zephyr ADC API. Generate needed global variables/types: enum adc_channel and adc_channels from dts. Once ADC_CMD config is enabled, it replaces the "adc" Zephyr console function. The shim assues only ADC_0 module. More specific channel options can be added to named-adc.yaml e.g. shift or gain.
