The patch regulator: act8865 regulator modes and suspend states has been applied to the regulator tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.4 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 >From ff461ebfd4b7051d9b79ca023741e6c2d960a912 Mon Sep 17 00:00:00 2001 From: Raag Jadav <raagjadav@xxxxxxxxx> Date: Wed, 14 Aug 2019 00:02:56 +0530 Subject: [PATCH] regulator: act8865 regulator modes and suspend states Add documentation for act8865 regulator modes and suspend states. Add active-semi,8865-regulator.h file for device tree binding constants for act8865 regulators.
