    Subject[PATCH v4 0/8] iio: stm32-adc: add support of adc for stm32mp13
    Date
    On STM32MP13 SoCs, each ADC peripheral has a single ADC block.
    These ADC peripherals, ADC1 and ADC2, are fully independent.
    The STM32MP131 SoC provides only ADC2, while other STM32MP13x
    SoCs provide both ADC1 and ADC2.

    The STM32MP13 ADC features and characteristics are slightly
    different from STM32MP15 ADC ones, requiring a specific support
    in the driver.

    This patchset enables the ADC peripheral on STM32MP135F-DK board.

    On STM32MP135F-DK board the ADC is connected to VDDA voltage
    provided by the PMIC LOD1 supply, which has to be enabled through
    SCMI regulator framework.
    This serie introduces a fixed regulator to allow ADC probing,
    while SCMI regulators support is not available. This does
    not ensure ADC regulator enabling however.

    Changes in v4:
    - reformat patch 1 commit message
    - reorder adc1 node

    v3:
    - Remove blank line in tag block
    - Use HZ_PER_MHZ unit for max frequency definition
    - Coding style updates

    v2:
    - Rework commit message length
    - Add missing spaces
    - Remove useless defines
