The patch ASoC: AMD: Add a fix voltage regulator for DA7219 and ADAU7002 has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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 c183fec10ae6b3d1dfb77471d4158e576f6b43ae Mon Sep 17 00:00:00 2001 From: Akshu Agrawal <akshu.agrawal@amd.com> Date: Wed, 25 Jul 2018 17:00:59 +0800 Subject: [PATCH] ASoC: AMD: Add a fix voltage regulator for DA7219 and ADAU7002

DA7219 for our platform need to be configured for 1.8V. Hence, we add a volatge regulator with supplies of 1.8V in the machine driver.
