[PATCH 0/4] regulator: da9211: support changing modes

[Anand K Mistry]

This patchset adds support for being able to change regulator modes for
the da9211 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used in the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.

[PATCH 4/4] arm64: dts: mediatek: Update allowed regulator modes for elm boards

[Anand K Mistry]

This sets the allowed regulator modes for elm (and derivative) boards.
According to the datasheet, the da9211 does not support SLEEP mode.

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
