The patch regulator: DT: Add settling time property for non-linear voltage change has been applied to the regulator tree at git://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.

On such cases, the settling time for voltage change is treated as constant time. Add DT property for providing the settling time for any level of voltage change for non-linear voltage change. signed-off-by: Laxman Dewangan <ldewangan@xxxxxxxxxx> Acked-by: Rob Herring <robh@xxxxxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- Documentation/devicetree/bindings/regulator/regulator.txt | 3 +++ 1 file changed, 3 insertions(+) diff --git a/Documentation/devicetree/bindings/regulator/regulator.txt b/Documentation/devicetree/bindings/regulator/regulator.txt index 6ab5aef619d9..d18edb075e1c 100644 --- a/Documentation/devicetree/bindings/regulator/regulator.txt +++ b/Documentation/devicetree/bindings/regulator/regulator.txt @@ -21,6 +21,9 @@ Optional properties: design requires.
