Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next Thanks! [1/1] regulator: da9211: add cache_type commit: 989e08c3d0044fc707c26c0329ed49e33e8e4c7b 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

Add regmap_cache to reduce wakeups events of interrupt if regulator is accessed frequently. This results in saving more power.
