The patch regulator: added support for suspend states has been applied to the regulator tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 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.

There are many of these modes depending on the particular runtime state. Currently the regulator consumers are not granted permission to change suspend state of regulator devices, the constraints are configured at startup. In order to allow changes in a vlotage range, we need to add new properties for voltage range and a flag to give permission to change the suspend voltage and suspend on/off in suspend mode.
