[PATCH v2 0/7] Add input voltage suppliers for PMIC MCP16502 regulators

[PATCH v2 0/7] Add input voltage suppliers for PMIC MCP16502 regulators

[Andrei Simion]

In this series of patches, support for the *-supply property [1]  is added
(correlated with supply_name [2]) from the core regulator.
Link [1]: https://github.com/torvalds/linux/blob/master/drivers/regulator/core.c#L471
Link [2]: https://github.com/torvalds/linux/blob/master/drivers/regulator/core.c#L2064

I modified the mcp16502.c driver and the dts that use this PMIC.
We added these improvements to provide a complete description of the board power scheme.

Snippet (as an example) from /sys/kernel/debug/regulator/regulator_summary
(for at91-sama7g5ek):

[PATCH v2 1/7] regulator: mcp16502: Add supplier for regulators

[Andrei Simion]

Based on the datasheet [1] (Block Diagram) PVIN[1-4] and LVIN
represent the input voltage supply for each BUCKs respective LDOs.
Update the driver to align with the datasheet [1].

If there is going to be respin, drop phandle. Stating obvious is not
helping - you describe here hardware, not DT.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y microchip/at91-sama5d29_curiosity.dtb microchip/at91-sama5d2_icp.dtb microchip/at91-sama7g54_curiosity.dtb microchip/at91-sama7g5ek.dtb' for 20240812135231.43744-1-andrei.simion@microchip.com:

Thanks!

[1/7] regulator: mcp16502: Add supplier for regulators
      commit: 861289835002b733aa8715442ba555b1daa84baa
[2/7] regulator: dt-bindings: microchip,mcp16502: Add voltage input supply documentation
      commit: bf5ba94fa0b90c9433167bf143780af6c8805479

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
