[U-Boot] [PATCH v2 0/6] Add support for STM32 ADC

[Fabrice Gasnier]

This series adds support for STM32 Analog to Digital Converter.
STM32 ADC support is originally based on Linux kernel v4.18-rcs:
- First two patches brings some changes in clk and adc uclass
- Next two patches add STM32 ADC dt-bindings and driver for STM32MP1 and
  STM32H7
- Last patches add config and DT on stm32mp15

Changes in v2:
- add test case for 'clk_valid()', e.g. in test/dm/clk.c and sandbox.
- Update TRUE/FALSE comments to lower case: true/false
- move device_get_supply_regulator() call to pre_probe() routine

Fabrice Gasnier (6):
  clk: add clk_valid()
  dm: adc: uclass: get reference regulator once
  dt-bindings: Document STM32 ADC DT bindings
  adc: Add driver for STM32 ADC
  configs: stm32mp15: enable ADC
  ARM: dts: stm32mp157: Add ADC DT node
