The patch regulator: core: Define regulator_set_voltage_triplet()
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. Thanks, Mark >From 30f93ca8323f0c21b789bea0f7db8e8e3a7915c6 Mon Sep 17 00:00:00 2001 From: Viresh Kumar <[email protected]> Date: Mon, 17 Aug 2015 08:16:51 +0530 Subject: [PATCH] regulator: core: Define regulator_set_voltage_triplet() Voltage tolerance isn't necessarily same on both sides of the target voltage and regulator_set_voltage_tol() wouldn't be suitable in such cases. Add another routine regulator_set_voltage_triplet(), which accepts target, min and max voltages as arguments. This first tries to set the voltage between the target voltage and the upper limit, then fall back on the full range. The idea behind this is to set regulator's voltage as close to the target voltage, as possible. Based on regulator_set_voltage_tol().
