The patch regulator: max77686: Pass descriptor instead of GPIO number
has been applied to the regulator tree at https://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 96392c3d8ca47f6654dfa40680c926b1a3419754 Mon Sep 17 00:00:00 2001 From: Linus Walleij <[email protected]> Date: Thu, 15 Nov 2018 09:01:19 +0100 Subject: [PATCH] regulator: max77686: Pass descriptor instead of GPIO number Instead of passing a global GPIO number, pass a descriptor looked up from the device tree configuration node. Tested on Odroid U3 (with max77686 although not using any GPIOs for regulators, so at least default paths are not broken).
