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 f2988afedf2c19880a3c65d79dfc7939e1b53d8a Mon Sep 17 00:00:00 2001 From: Oder Chiou Date: Thu, 27 Aug 2015 15:14:51 +0800 Subject: [PATCH] ASoC: rt5645: Prevent the pop sound of the headphone while rebooting or shutdowning Add i2c shutdown function to prevent the pop sound of the headphone while the system is rebooting or shutdowning. It de-initials the jack detection function, and it cannot be turned off in _BIAS_OFF. If we don't de-initial it, the pop sound will be heard in the situation of powering off. And replace the related register settings from magic number to meaningful defined name.
