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 3fb2ef111d6f799f3da8860c1a90ef3d9c36ea55 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 24 Jun 2016 13:58:09 +0530 Subject: [PATCH] regulator: tps65218: force set power-up/down strobe to 3 for dcdc3 The reset value for this register seems broken on certain versions of tps65218 chip, so make sure the dcdc3 settings is proper. Needed for proper functionality of rtc+ddr / rtc-only modes.
