The patch ASoC: rt5651: Only configure LDO voltage once at boot 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 3d7719d3cc8efe88be4c72cb7cbb0d866ed7d1b2 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Sun, 25 Feb 2018 11:46:53 +0100 Subject: [PATCH] ASoC: rt5651: Only configure LDO voltage once at boot Now that rt5651_set_bias_level(BIAS_OFF) no longer modifies the LDO voltage selection bits, there is no need to set them each time we move to standby. Instead configure them once at component-probe() time.
