The patch regulator: of: Use of_property_read_u32() for reading min/max
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 a34785f10d33f70680941da284d7ec3a612aad1a Mon Sep 17 00:00:00 2001 From: Laxman Dewangan <[email protected]> Date: Thu, 10 Mar 2016 17:42:47 +0530 Subject: [PATCH] regulator: of: Use of_property_read_u32() for reading min/max OF interface provides to read the u32 value via standard interface of_property_read_u32(). Use this API to read "regulator-min-microvolts" and "regulator-max-microvolt". This will make consistent with other property value reads.
