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 9ae5cc75ceaacf69cc50b9fd4713276c2aa62eb9 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 14 May 2018 10:06:32 +0200 Subject: [PATCH] regulator: s5m8767: Pass descriptor instead of GPIO number Instead of passing a global GPIO number for the enable GPIO, pass a descriptor looked up from the device tree node for the regulator. This regulator supports passing platform data, but enable/sleep regulators are looked up from the device tree exclusively, so we can need not touch other files.
