Introduce a new binding for the power controller of STM32H7 series. Signed-off-by: Mathieu Choplain <[email protected]>
Add node representing the Power Controller to SoC DTSI of STM32H7 series, and update DTS of all STM32H7-based boards since the new node has required properties. Signed-off-by: Mathieu Choplain <[email protected]>
Replace the existing infrastructure to specify power supply configuration through Kconfig with Devicetree. Also update all boards that were defining the Kconfig to no longer do so. Signed-off-by: Mathieu Choplain <[email protected]>

Introduce power controller binding for series equipped with two voltage regulators (LDO + SMPS). Signed-off-by: Mathieu Choplain <[email protected]>
Replace the existing infrastructure to specify power supply configuration through Kconfig with Devicetree. Set the LDO as default to reduce out-of-tree breakage - most users were relying on LDO being the default and it is harmless to use LDO if board is designed for SMPS. (Existing SMPS users should break anyways since the Kconfig symbol no longer exists, but this ensures they actively set the power supply to SMPS in DT) Signed-off-by: Mathieu Choplain <[email protected]>

Replace the existing Kconfig-based mechanism to select the power supply with a Devicetree-based approach, inspired by the STM32WB0 implementation.
Commits could be reorganized: currently, they're split by series, but also squash SoC DTSI and board DTS changes together - I could mark properties as not required initially then perform updates separately, and make required in a last-pass commit if that sounds cleaner.
