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 Acked-by: Rob Herring Signed-off-by: Mark Brown --- 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.
