From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Brown Subject: Applied "regulator: tps65090: Pass descriptor instead of GPIO number" to the regulator tree Date: Thu, 24 May 2018 20:13:54 +0100 Message-ID: References: <20180212131717.27193-16-linus.walleij@linaro.org> Return-path: In-Reply-To: <20180212131717.27193-16-linus.walleij@linaro.org> Sender: linux-kernel-owner@vger.kernel.org To: Linus Walleij Cc: Lee Jones , Mark Brown , Liam Girdwood Mark Brown , linux-kernel@vger.kernel.org, linux-gpio@vger.kernel.orgLee Jones linux-kernel@vger.kernel.org List-Id: linux-gpio@vger.kernel.org The patch regulator: tps65090: 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 3012e81446d011c1bd99812e562e2292f21060fb Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 14 May 2018 10:06:33 +0200 Subject: [PATCH] regulator: tps65090: 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.
