kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

# ADC configuration options
drivers: adc: add driver support for ADC1 of stm32 This commit adds driver support for ADC1 on all 8 supported series of stm32 with resolution and conversion time selection and calibration. Currently DMA is not supported for all series, and without it, zephyr won't be able to catch up ADC's end of conversion interrupt, so this version of the driver supports one channel conversion only. Users want multi-channel conversion should use multiple sequences in their app code. This driver uses LL lib rather than HAL because the current HAL lib for ADC will call HAL_DMA_* functions rather than using zephyr's common DMA interface, so that way the driver will break the consistency of the code. This driver has been tested on multiple nucleo boards including NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all passed the test cases in tests/drivers/adc/adc_api. If the external ADC line is floating, it may fail the tests since ADC may get 0V and the test cases think 0 is failing. Connect it to any voltage source between 0-3.3V will help passing the test cases. Signed-off-by: Song Qiang <songqiang1304521@gmail.com>

drivers/adc: stm32: Don't enable ADC instance by default in driver ADC_1 peripheral instance was enabled by default in driver. This is not the usual way to enable peripheral instances, as it makes board configuration unclear. Move activation in boards that are declaring ADC support.
