This series adds support for the SARADC IP block found in the Amlogic
Meson S4 (S905Y4) SoC and enables it for the Khadas VIM1S board.

Changes in v2:
- Addressed feedback from Krzysztof Kozlowski:
  - Updated dt-bindings commit message to explain the hardware compatibility.
  - Separated the S4 compatible string in the YAML bindings to ensure it
    correctly falls back to the specific "amlogic,meson-g12a-saradc" rather
    than the generic "amlogic,meson-saradc".
  - Updated the S4 SoC dtsi to use the correct G12A fallback.
- Added Martin's Reviewed-by tags where appropriate.
- Link to v1: https://lore.kernel.org/all/20260228065840.702651-1-nick@khadas.com/
