This patchset adds support of ADC2 internal channels VDDCORE, VREFINT and VBAT
on STM32MP15x SoCs. The generic IIO channel bindings is also introduced here
to provide this feature. The legacy channel binding is kept for backward compatibility.
Changes in v2:
- Add 'deprecated' to channels legacy properties in ADC bindings
- Add set/clr service for common registers, to make code more generic in
internal channels enable/disable services.
- Expose vrefint channel as a processed channel to return
the actual value of vrefp.
- Minor code improvements
